Hiring a B2B SEO agency should give you more than higher rankings. The right partner should help your company appear when buyers research a problem, compare vendors, and build a shortlist—then show you whether that visibility is producing qualified leads and pipeline.
Yet “B2B SEO agency” has become a loose label. One firm may specialize in enterprise technical SEO. Another may mainly publish content for SaaS companies. A third may be better at industrial websites, multilingual campaigns, or digital PR. Put them in the same pitch process without deciding what you need, and you’ll receive proposals that are difficult to compare.
The better approach is to choose around your immediate constraint. Do you need to fix a complex website, reach engineers and procurement teams, generate more demos from commercial searches, or appear in Google and AI answers?
I researched 15 B2B SEO agencies and organized them by the problem each one is best equipped to solve. You’ll see their services, published results, pricing information, strengths, limitations, and the type of company that should shortlist each firm.
Quick comparison of the best B2B SEO agencies

What does a B2B SEO agency do?
A B2B SEO agency helps a company capture demand from people searching on behalf of a business. That sounds similar to general SEO, but the buying journey changes the work.
Your search market may be small. The product may take several conversations to understand. A finance lead, technical user, department head, and procurement team may all evaluate the same purchase from different angles.
The conversion is also less likely to be an immediate checkout. You may be trying to generate demo requests, consultations, requests for proposals, or sales-qualified leads.
A capable B2B agency connects keyword research to those buyers and conversion paths. Its work may include technical audits, competitor research, product and use-case pages, comparison content, thought leadership, digital PR, link building, conversion optimization, and reporting that connects organic activity to pipeline.
The scope varies considerably. A company with a large, complicated website may need one of the best enterprise SEO agencies. A lean SaaS team may need content and links more than ongoing technical support.
If you are still deciding whether to hire externally at all, this guide to outsourcing SEO services breaks down the common models.
How I selected these B2B SEO agencies
I assessed the agencies on this list using information available on their websites, service pages, case studies, pricing pages, client portfolios, and recent third-party coverage.
To make the list, an agency needed meaningful B2B experience, a clear SEO capability, public evidence of its work, and a reason for a specific buyer to choose it. I also favored agencies that explain how they handle technical SEO, content, authority, conversions, or AI search instead of relying on broad claims about growth.
The ordering is not a universal ranking. It creates a useful mix of large and smaller firms across software, industrial, professional-services, international, and enterprise markets. Before signing a contract, use these profiles to build a shortlist, then follow a structured process for finding a good SEO company.
1. Directive Consulting: Best for enterprise B2B SEO and performance marketing
Best for: Established B2B companies that want SEO coordinated with paid acquisition, conversion optimization, and broader performance marketing.
Directive Consulting is one of the larger firms on this list. Its SEO service covers technical audits, buyer-intent content, on-page optimization, off-page authority, and measurement.
The agency also offers paid media, lifecycle marketing, design, and video, which makes it suitable for a marketing leader who wants organic search managed within a wider acquisition program.
Directive’s strongest fit is an enterprise B2B technology or services company with several marketing channels, a complex reporting setup, and enough internal support to implement recommendations. Its published client list includes Amazon, Gong, HP, and Seagate. Directive also maintains a large success-story library, although the level of detail varies by case study.
Directive Consulting pros and cons
Pros
- Combines technical SEO, content, paid media, and conversion work in one engagement.
- Has experience with enterprise B2B brands and the operational complexity that comes with them.
- Frames SEO around buyer intent, pipeline, and revenue instead of reporting traffic alone.
Cons
- The breadth of the offering can be excessive when you only need a focused technical audit or a small content program.
- A large agency model may involve more account and process layers than a smaller company wants.
Who should choose Directive Consulting?
Choose Directive when SEO is one part of a larger demand-generation problem. It belongs on your shortlist if your organic and paid teams operate separately, high traffic is not producing enough qualified pipeline, or leadership wants a coordinated view of acquisition performance. A company seeking only SEO content production can find a leaner option elsewhere.
Directive Consulting pricing
Directive provides custom proposals. Its 2026 enterprise SEO pricing guide places enterprise retainers between $7,000 and $60,000+ per month, depending on website complexity, competition, and geographic scope.
2. Omniscient Digital: Best for B2B SaaS organic growth tied to pipeline
Best for: Established B2B software companies that want SEO, GEO, content, and digital PR managed as one organic growth program.
Omniscient Digital works specifically with B2B software companies. Its strategy process includes buyer research, competitor analysis, keyword exploration, product alignment, SME interviews, content gaps, and AI citation analysis.
The agency then supports execution through content production, optimization, digital PR, and link building.
The distinction is measurement. Omniscient publishes case studies around pipeline and revenue, not only rankings. Its case-study library says it helped SpotDraft generate $2.94 million in pipeline.
Other published results include $3.7 million in qualified pipeline for Smartling and $4 million in blog-attributed ARR for Jasper. These are agency-reported results, but they show the commercial standard the firm expects its programs to meet.
Omniscient Digital pros and cons
Pros
- Deep specialization in B2B SaaS, with clients including Jasper, Smartling, Convert, and 360Learning.
- Integrates traditional SEO with GEO, digital PR, content, and pipeline attribution.
- Starts with buyer and product research before turning the plan into a publishing schedule.
Cons
- The narrow B2B software focus makes it less suitable for manufacturers, local businesses, or consumer brands.
- Its minimum engagement is beyond the budget of many early-stage companies.
Who should choose Omniscient Digital?
Choose Omniscient when you have product-market fit, a defined sales process, and enough marketing data to connect organic activity to opportunities.
It is particularly strong for a Series B or later SaaS company that wants a full organic program rather than separate writers, SEO consultants, and digital PR vendors. Early-stage teams may get more value from a focused strategy project or a smaller production partner.
Omniscient Digital pricing
Full-service engagements start at $10,000 per month. Its standalone SEO and content strategy package starts at $15,000.
3. Windmill Strategy: Best for industrial and manufacturing companies
Best for: Manufacturers, engineering firms, automation companies, and other technical B2B businesses with complex products and long buying cycles.
Windmill Strategy understands a search problem many generalist agencies struggle with: the customer may search by material, specification, process, part, certification, or technical application rather than by a broad product category.
Its SEO work includes keyword research, technical optimization, content strategy, measurement, and ongoing improvement.
Windmill also designs and develops industrial websites to address the relationship between information architecture, product detail, conversion paths, and organic search. That matters when the current site was built around an internal product catalog rather than the way engineers, distributors, and procurement teams research suppliers.
The agency’s published work for precision filtration manufacturer Mott Corporation reports a 63.6% increase in organic form submissions alongside its paid-search improvements. Its case-study library spans industrial manufacturing, automation, engineering, technology, life science, and B2B medical companies.
Windmill Strategy pros and cons
Pros
- Clear focus on industrial, manufacturing, engineering, and technical markets.
- Can combine SEO with a website redesign when poor structure or UX limits performance.
- Understands the subject-matter access and technical accuracy required for industrial content.
Cons
- Not the obvious choice for a SaaS company that needs a high-volume blog and product-led content program.
- Website projects can expand the budget and timeline beyond a narrow SEO engagement.
Who should choose Windmill Strategy?
Shortlist Windmill when your website must explain a large product catalog, technical capabilities, or several applications to a specialized buyer.
It is a stronger fit when SEO improvements depend on restructuring the website or clarifying complicated offerings. If your technical foundation is already sound and the main gap is article production, a dedicated content partner may be enough.
Windmill Strategy pricing
Windmill Strategy provides custom quotes based on the mix of website, SEO, content, and paid-media support required.
4. iPullRank: Best for technical SEO and AI search on complex websites
Best for: Enterprise companies with large websites, difficult technical problems, and the internal resources to implement sophisticated recommendations.
iPullRank is a strong technical option for publishers, financial institutions, marketplaces, ecommerce companies, and enterprises managing thousands or millions of URLs.
Its services include technical SEO, content strategy, content engineering, audience research, relevance engineering, generative AI, and AI search strategy.
Michael King leads the agency and has built a reputation around rigorous search research. Its approach goes beyond a standard crawl report. Relevance engineering connects audience needs, content, technical signals, and measurement so a company can decide which changes will affect organic performance. That depth is useful during migrations, programmatic SEO projects, indexation problems, and large-scale content optimization.
iPullRank says its work has generated more than $5 billion in organic search results for clients. One published marketplace case study reports $290 million in revenue, a 175% year-over-year revenue increase, and 5.4 million additional organic sessions. Those numbers come from the agency’s own case study.
iPullRank pros and cons
Pros
- Deep technical SEO, content engineering, and AI-search capability.
- Well suited to sites with complicated templates, migrations, taxonomies, or large URL inventories.
- Strong research and thought leadership from an experienced search team.
Cons
- Too advanced for a small B2B website whose main problem is a lack of high-quality pages.
- Recommendations may require developers, analysts, and internal stakeholders to execute.
- Pricing is not published, and an enterprise engagement is unlikely to suit a modest budget.
Who should choose iPullRank?
Choose iPullRank when the business case for SEO is large, and the technical environment is complex. It is an excellent RFP candidate for a migration, enterprise audit, content system, or AI-search program.
iPullRank pricing
iPullRank uses custom pricing. Its public cost analysis illustrates how expensive enterprise execution can become, but it does not publish standard agency packages.
5. Sagefrog: Best for established B2B companies needing integrated marketing
Best for: Healthcare, professional-services, industrial, and technology companies that want SEO managed alongside content, paid media, branding, and marketing operations.
Sagefrog is a broader B2B marketing agency rather than an SEO-only firm. Its services cover strategy, branding, websites, content, search, paid media, HubSpot, and marketing operations. That mix suits a small or midsized B2B marketing department that needs one partner to plan and execute several parts of the program.
SEO sits inside Sagefrog’s content and digital work. The agency performs content audits, develops assets for different stages of the buyer journey, and uses search optimization to attract relevant visitors. It also works across several non-SaaS markets, including healthcare, industrial, and professional services.
Its Razor Technology case study reports a 132% increase in new contacts, a 2x increase in marketing-qualified leads, and an 8:1 return on investment. The CLX Logistics case study shows how the agency combined website work, content, SEO, paid search, email, media outreach, and webinars rather than treating organic search as an isolated channel.
Sagefrog pros and cons
Pros
- Offers a broad B2B marketing service for teams that need more than SEO.
- Experience spans healthcare, industrial, technology, logistics, and professional services.
- Can connect SEO content to paid campaigns, websites, CRM workflows, and sales enablement.
Cons
- SEO does not receive the singular focus it would at a technical search consultancy.
- A bundled program may include services your team already handles well.
Who should choose Sagefrog?
Choose Sagefrog when the marketing gap crosses several channels and hiring separate agencies would create too much coordination. It is particularly useful for an established B2B company with a lean internal team, an underdeveloped digital program, and a need for consistent execution. If you already have brand, paid media, operations, and strategy covered, hire a more focused SEO partner.
Sagefrog pricing
Sagefrog provides custom proposals based on services and scope.
6. Grow and Convert: Best for bottom-funnel content that generates demos
Best for: SaaS and service businesses that want content performance measured by demos, trials, and leads rather than publishing volume.
Grow and Convert built its service around Pain Point SEO. The agency interviews customers and internal experts, identifies searches with buying intent, creates detailed content for those terms, promotes the pages, and tracks conversions down to the article level.
This makes Grow and Convert a strong choice when a blog already attracts traffic but contributes little to pipeline. Its strategy often begins with category, comparison, alternatives, use-case, and problem-aware terms rather than high-volume educational keywords.
The agency’s end-to-end service includes keyword research, SERP analysis, expert interviews, writing, publishing, technical audits, link building, and conversion tracking.
The proof is unusually specific. Grow and Convert reports that its Smartlook program produced 600+ trials and demos per month, with 37 of 50 target keywords reaching the top 10. Another SaaS case study reports 150+ demo requests per month, while its Leadfeeder work reached more than 200 monthly signups.
Grow and Convert pros and cons
Pros
- Clear focus on high-intent keywords and content-attributed conversions.
- Handles research, interviews, writing, publishing, link building, and measurement.
- Publishes detailed case studies that show the strategy and outcomes.
Cons
- The model prioritizes a small number of deep articles rather than high publishing volume.
- It is not the right first call for a major migration or difficult enterprise technical problem.
- The monthly fee can feel high if you compare it only by article count.
Who should choose Grow and Convert?
Choose Grow and Convert when you can define a valuable conversion and want the agency accountable for generating more of it. It is particularly well matched to SaaS demos, trials, and qualified service leads. Teams that want to apply the approach internally can begin by learning how to find bottom-of-funnel keywords.
Grow and Convert pricing
Grow and Convert has publicly discussed charging around $10,000 per month for its service. Confirm current scope and pricing directly with the agency.
7. Ironpaper: Best for combining SEO with B2B demand generation
Best for: B2B service, technology, logistics, energy, healthcare, and manufacturing companies that need search visibility to turn into qualified sales opportunities.
Ironpaper treats SEO as part of a wider demand-generation system. The New York agency works across content strategy, websites, account-based marketing, sales enablement, lead generation, and campaign optimization. Its industry experience extends beyond software to consulting, logistics, energy, healthcare, industrial, and nonprofit organizations.
That scope is useful when the website attracts the wrong visitors or hands weak leads to sales. Ironpaper can assess the search market, value proposition, information architecture, conversion journey, content, and CRM handoff rather than improving rankings in isolation.
Its published work for Goddard, a product development company serving medical devices, life sciences, and industrial robotics, began with a familiar B2B problem: spam and unqualified inquiries rather than useful opportunities.
Ironpaper repositioned the digital program around qualified lead generation and HubSpot. A separate PCS Software case study describes competitor SEO analysis, information architecture review, behavioral analytics, heat maps, and user-flow assessment.
Ironpaper pros and cons
Pros
- Strong fit for complex B2B services and technical industries outside SaaS.
- Connects SEO with messaging, conversion paths, sales enablement, and lead management.
- Can support a website and demand-generation program through one team.
Cons
- Public case studies do not always provide enough numerical SEO detail for easy comparison.
- The broad service model may be unnecessary for a mature marketing team with one isolated search problem.
Who should choose Ironpaper?
Choose Ironpaper when sales lead quality matters more than raw traffic, and the solution requires changes across the website, content, and marketing-to-sales journey. It is a sensible shortlist option for a technical B2B company whose current website does not explain the offer or qualify prospects well.
Ironpaper pricing
Ironpaper provides custom pricing after assessing the company, market, and required program.
8. Siege Media: Best for SEO content, design, and digital PR at scale
Best for: Established brands that need a consistent pipeline of search-led content, original visual assets, and links.
Siege Media is a content marketing agency with a strong SEO foundation. It combines strategy, writing, design, interactive assets, and digital PR.
The team says it spends almost half of its content creation time on design and frequently creates calculators, maps, quizzes, and other assets that make a page more useful and linkable.
Siege works with B2B and consumer brands, including Asana, Intuit, Zapier, Zendesk, and Zoom. Its current service page says client work has driven more than $100 million in results, while its 2026 agency roundup reports approximately $148 million in annual client traffic value.
Because traffic value is an SEO-tool estimate rather than booked revenue, use the figure as evidence of organic scale, not financial return.
Siege Media pros and cons
Pros
- Combines SEO strategy, editorial production, design, and link acquisition.
- Large portfolio and established process for producing content at scale.
- Particularly strong when visual or interactive assets can improve usefulness and earn coverage.
Cons
- A content-led model may not solve deep technical SEO problems on its own.
- The service can be more production capacity than a small B2B company needs.
- Custom pricing makes it difficult to assess fit before a sales conversation.
Who should choose Siege Media?
Choose Siege when your technical foundation is sound, and the growth constraint is producing enough competitive content and earning the authority to rank it. I
t suits an established company with a broad keyword market and the budget to publish consistently. Compare it with other content strategy agencies if editorial scale is the main requirement.
Siege Media pricing
Siege uses custom pricing based on projected opportunity and budget. Its general pricing guide places professional SEO campaigns anywhere from $5,000 per month.
9. Straight North: Best for lead generation in industrial and service businesses
Best for: Small and midsized B2B manufacturers, distributors, and service companies that want SEO, PPC, and website support from one established provider.
Straight North has provided B2B SEO services for more than two decades. Its model focuses on the search terms engineers, procurement managers, owners, and other business buyers use when looking for products or services. The wider agency also provides paid search, web design, creative, and conversion services.
Straight North is a practical option for a company that needs steady lead generation rather than an experimental content program. Its SEO work can include research, on-page optimization, technical changes, content, link acquisition, and reporting. The breadth is particularly useful for a manufacturer or business-services firm with an outdated website and limited in-house digital expertise.
It publishes related success stories on its service pages, although several are downloadable PDFs and the public summaries do not make cross-client comparison easy.
Straight North pros and cons
Pros
- Long history serving both B2B and B2C companies, including industrial markets.
- Can combine SEO with paid search, website work, and conversion tracking.
- Suitable for smaller and midsized companies that may not fit an enterprise consultancy.
Cons
- Generalist reach means less specialization in B2B SaaS or AI search than some firms here.
- Public case-study detail is less accessible than at agencies that publish long written breakdowns.
- Monthly plans require a custom sales conversation.
Who should choose Straight North?
Choose Straight North when the immediate goal is more qualified inquiries from search and your company needs practical implementation across the website. It belongs on a shortlist for manufacturers, distributors, professional services, and multi-location B2B companies.
Companies focused on a local footprint can also compare dedicated local SEO tools before deciding what to manage internally.
Straight North pricing
Straight North advertises monthly SEO plans but does not publish prices. Quotes are customized to the campaign.
10. Duffy Agency: Best for international B2B expansion
Best for: B2B brands entering new countries that need local-market research, positioning, messaging, and localization before scaling search activity.
Duffy Agency helps companies expand across borders. Its work includes voice-of-customer research, local-market research, brand strategy, messaging, localization, communication planning, training, and fractional marketing support.
It has served international clients since 2001 and works with a network of partner agencies across six continents.
Duffy is the outlier on this list because its current website does not position the firm as an SEO-first execution agency. That limitation is also the reason it may be useful.
International SEO fails when a company simply translates English pages and keeps the same keywords, value proposition, proof, and channel plan in every market. Duffy’s research and localization work can establish the market understanding that a regional SEO program needs.
Duffy Agency pros and cons
Pros
- Deep focus on international markets, cross-border positioning, and localization.
- Can research how buyers in each country describe the problem and evaluate providers.
- Partner network provides support across regions without relying on one central team for every local nuance.
Cons
- Not a conventional technical SEO or content-production agency based on its current service positioning.
- You may still need an SEO implementation partner for audits, page production, links, and reporting.
Who should choose Duffy Agency?
Choose Duffy when the hard part is understanding and entering a new market, not fixing title tags on an existing domestic site.
They can help define the audience, language, message, and localization plan before SEO execution begins. A company looking for one vendor to manage a multilingual search campaign end-to-end should ask detailed questions about technical delivery, content production, and regional link acquisition.
Duffy Agency pricing
Duffy provides custom proposals for research, strategy, localization, and ongoing marketing support.
11. Foundation: Best for content distribution and AI visibility
Best for: Mid-market and enterprise B2B technology companies that want content to travel across search, AI answers, social platforms, and online communities.
Foundation approaches organic growth through creation and distribution. Its work covers SEO, content strategy, production, repurposing, and distribution across search, social, Reddit, and the sources AI systems use. That makes the agency a useful option when your company publishes credible material but struggles to earn attention outside its own website.
Foundation’s public research is a major part of its positioning. The team regularly breaks down how companies such as Zapier, Webflow, and Datadog grow through content and search.
Its case-study library includes an audience-intelligence platform that achieved more than a 300% increase in social engagement after using content creation, distribution, and repurposing. The agency also describes itself as an AI visibility partner for B2B tech and SaaS companies.
Foundation pros and cons
Pros
- Strong content-distribution capability rather than a publish-and-wait SEO model.
- Extensive experience analyzing and working with B2B technology companies.
- Connects SEO with AI visibility, social channels, repurposing, and community distribution.
Cons
- Technology and SaaS specialization makes it less natural for industrial or local B2B companies.
- Public case studies do not always isolate the SEO contribution from broader content and distribution work.
Who should choose Foundation?
Choose Foundation when production alone is not your constraint. The stronger use case is a B2B tech company that needs research-backed content and a deliberate plan to distribute it across the places buyers and AI systems discover information.
If your primary concern is measurement, pair the program with one of the best rank tracking tools and clear pipeline attribution.
Foundation pricing
Foundation creates custom scopes and does not list public starting prices for agency engagements.
12. Perceptric: Best for conversion-led SEO and GEO
Best for: Growing B2B brands that want one partner for Google search, AI visibility, expert content, thought leadership, and paid distribution.
Perceptric is a smaller B2B organic growth agency that combines SEO, GEO, content marketing, LinkedIn thought leadership, and PPC. Its positioning is direct: use content and search visibility to produce pipeline rather than treating rankings or AI mentions as the finished result.
The service spans technical audits, high-intent content, AI-search optimization, interactive assets, and distribution.
Perceptric also has dedicated offers for professional-services firms, making it broader than the SaaS-only agencies on this list. Its professional-services page includes a client account of tripling organic traffic and increasing inquiries by 120%. However, the client is anonymized, and the result should be treated as agency-supplied testimonial evidence.
Perceptric pros and cons
Pros
- Integrates SEO and GEO with content, LinkedIn thought leadership, and paid distribution.
- Works with B2B SaaS and professional-services companies.
- Smaller agency model may provide closer access to senior team members.
Cons
- A shorter public track record and fewer named case studies than established agencies on this list.
- Broad claims about pipeline are harder to assess without detailed attribution case studies.
- May not have the scale required for a global enterprise website or large migration.
Who should choose Perceptric?
Choose Perceptric when you want a focused partner that can connect search content with founder or executive thought leadership and AI discovery.
It is a credible option for a growing B2B company that is too mature for ad hoc freelance support but does not need a large enterprise consultancy. Teams comparing newer AI-focused firms should also review these AI SEO agencies for B2B SaaS.
Perceptric pricing
Perceptric says professional-services clients typically spend $2,000 to $10,000 per month. Scope, production volume, and company size affect the final price.
13. Obility: Best for B2B technology companies with long sales cycles
Best for: B2B technology and software companies that want SEO, GEO, paid media, and revenue operations aligned around pipeline.
Obility has spent more than 15 years working with B2B technology companies. Its SEO programs are built for technical buyers, high-intent searches, and long sales cycles. The service now incorporates GEO and AEO tactics alongside technical health, content collections, content refreshes, and traditional organic search.
Obility’s wider capabilities include paid search, paid social, revenue operations, and creative. That combination is useful when organic visibility cannot be evaluated separately from campaign data, CRM stages, or pipeline reporting.
The agency’s case-study library reports a 75% increase in blog organic traffic, a 38% increase in website traffic, and a 56% increase in ranking keywords after migrating Revel Systems’ blog from a subdomain to the main domain. Its Boomi case study describes a combined SEO and GEO program designed to secure visibility in both traditional and AI-driven results.
Obility pros and cons
Pros
- Long-standing specialization in B2B tech and software.
- Combines SEO and GEO with paid media and revenue operations.
- Demonstrated experience with migrations, technical work, content, and pipeline measurement.
Cons
- Less suitable for manufacturers or professional-services firms outside its technology focus.
- A multi-channel engagement may be larger than a content-only team needs.
Who should choose Obility?
Choose Obility when you sell a technical product through a long sales process and need organic performance evaluated against lead and opportunity data.
It is also a strong option when the program spans SEO and paid channels or requires marketing-operations support. A company seeking only product-led articles can hire more narrowly.
Obility pricing
Obility provides custom quotes based on channel mix, scope, and company goals.
14. First Page Sage: Best for thought-leadership SEO and lead generation
Best for: B2B companies in complex industries that can commit to a long-term program of expert-led content and technical optimization.
First Page Sage combines technical SEO with a hub-and-spoke content model. The agency targets long-tail searches across the buying journey, then publishes thought-leadership content intended to rank and generate qualified leads.
Its B2B work spans SaaS, financial services, manufacturing, healthcare, construction, and other markets with complex products or services.
The agency emphasizes content written with subject-matter expertise, supported by technical audits and reporting across rankings, organic traffic, leads, and ROI. Its B2B service page highlights work for Cadence Design Systems, where the goal was to reach design engineers through thought-leadership SEO.
First Page Sage also publishes extensive benchmark reports on SEO pricing, conversion rates, and ROI. Those reports are self-published and often place the agency highly in its own rankings, so they should not replace an independent reference check. They do, however, make its operating model and commercial expectations easier to understand.
First Page Sage pros and cons
Pros
- Experience producing expert-led content for technical and regulated industries.
- Combines technical SEO, content, and lead-generation reporting.
- Broad B2B industry coverage beyond software.
Cons
- The thought-leadership model requires sustained access to internal expertise and a long-term commitment.
- Much of the public comparative research is published by First Page Sage itself.
Who should choose First Page Sage?
Choose First Page Sage when buyers need education before contacting sales and your company can supply experts. It is a strong fit for a complex B2B category where authority and a large body of connected content matter. Ask how the team will interview experts, validate technical claims, and distinguish your point of view from ranking competitors.
This guide to conducting expert interviews for articles shows the standard to expect.

15. RevenueZen: Best for B2B SEO tied to sourced revenue
Best for: B2B SaaS and service companies that want SME-led content, GEO, and reporting against leads, pipeline, and revenue.
RevenueZen begins with the ideal customer profile, business model, value proposition, and competitive gaps. Its services include B2B SEO, GEO, content marketing, analytics, performance reporting, content briefs, and LinkedIn content. The agency is a practical fit for a company that wants an organic program but does not need a large full-service performance-marketing firm.
RevenueZen’s case studies include several revenue-based outcomes. It reports that an enterprise compliance SaaS company sourced $3.8 million in pipeline from organic search in 12 months. Blueback Global generated a projected $80,000 in new ARR within six months, and Inside Sales Solutions generated $176,000 in revenue from B2B SEO in six months. Its StockIQ case study reports a 500% increase in organic leads within seven months.
RevenueZen pros and cons
Pros
- Publishes case studies with pipeline, revenue, lead, and ROI outcomes.
- Combines SEO, GEO, SME-led content, and analytics in one program.
- Serves both B2B SaaS and service businesses.
Cons
- Less suited to an enterprise site requiring large-scale technical engineering.
- The content-led model depends on access to internal expertise and product knowledge.
- Typical retainers may be high for an early-stage company without a proven sales process.
Who should choose RevenueZen?
Choose RevenueZen when you want a focused B2B organic partner and can track leads through the sales process.
It is particularly suitable for a company that has validated its offer and now needs repeatable content, search visibility, and conversion measurement. The revenue case studies make it easier to ask concrete questions about attribution during the sales process.
RevenueZen pricing
RevenueZen says its B2B SEO campaigns average $6,500 to $9,000 per month for clients that see the strongest results.
How to choose a B2B SEO agency
Start with the problem you need the agency to solve. A familiar client logo does not prove the firm is right for your website, market, or team.
Match the agency to your main constraint
Choose iPullRank or another enterprise consultancy when technical complexity, migrations, or a huge URL inventory limits growth.
Consider Windmill Strategy for an industrial website that needs better structure and technical product content.
Grow and Convert fits a company that needs high-intent articles to produce more demos. Duffy Agency becomes relevant when international market understanding and localization come before execution.
This diagnosis also tells you which capabilities do not need to be in the contract. A technically healthy SaaS website may not need a recurring enterprise audit. A manufacturer redesigning a 15-year-old site probably needs more than four blog posts per month.
Ask for proof that resembles your goal
Request a case study from a similar business model, sales cycle, and starting point. A traffic result for a consumer publisher says little about the agency’s ability to generate enterprise demo requests. Ask what the agency delivered, what the client implemented, how long the result took, and how it was measured.
Inspect the proposed team and workflow
Find out who will lead strategy, perform technical work, interview experts, write content, edit drafts, build links, and report results. Ask whether those people are employees, contractors, or an external production partner. The answer affects communication, subject-matter depth, and consistency.
Define success before the engagement begins
Rankings and traffic remain useful diagnostic metrics, but a B2B program should also track relevant conversions. Depending on your sales motion, that may include demo requests, consultation bookings, qualified leads, product signups, influenced pipeline, or sourced revenue.
Your SEO tool stack should support the reporting plan rather than dictate it. Use SEO content audit tools to identify decaying or underperforming pages, but ask the agency to explain what it will change and why.
Check how the agency handles AI search
Every agency now has a GEO or AI-search story. Ask what the service changes in practice. Useful answers may cover prompt research, citation analysis, entity clarity, original data, expert input, third-party mentions, content structure, and measurement across AI platforms. Vague promises to “optimize for ChatGPT” are not enough.
If you want to understand the production side, this breakdown of what a GEO content writer does provides a practical baseline.
How much does a B2B SEO agency cost?
A focused B2B SEO engagement may start around $5,000, but established agencies commonly charge $7,500 to $15,000+ per month.
Enterprise programs can reach $60,000 or more per month when the scope includes several markets, large websites, technical implementation, content production, digital PR, analytics, and conversion work.
One-time projects are another option. A technical audit, content strategy, migration plan, or market analysis may cost $3,000 to $30,000+, depending on the site and deliverables.
Price alone does not tell you whether the proposal is expensive. Compare what the agency will own. A $10,000 retainer that includes research, technical work, content, design, links, and reporting is different from a $10,000 strategy fee that leaves implementation with your team.
The more useful calculation is the total cost of getting the work done. Include internal developer time, SME interviews, editing, design, publishing, tools, links, and management. For a wider benchmark, see this breakdown of content marketing agency pricing.
When a freelance B2B SEO writer makes more sense
An agency is not always the missing piece. You may already have an SEO strategy, technical support, reporting, and a link-building plan. The constraint may be producing the comparison pages, alternative articles, product reviews, software roundups, and how-to guides on the roadmap.
In that situation, a freelance SEO content writer can own the research, product testing, SME interviews, writing, on-page optimization, and revisions without adding a full agency retainer.
That is where I fit. I have written for HubSpot, Zapier, Vimeo, Paddle, MoEngage, Softr, Taboola, and other B2B software companies.
One article helped a client generate $36,000 in annual recurring revenue. My work has also earned #1 rankings, Google AI Overview placements, and substantial estimated traffic value for clients.
I don’t replace a technical SEO team, developer, or digital PR agency. I work alongside them when the company needs publish-ready content from someone who understands the product, can speak with internal experts, and can explain the buying decision clearly.
This model also suits companies that want to combine agency strategy with direct writer support. The agency-versus-freelancer comparison explains where each arrangement works best.
Choose the agency around the result you need
Don’t begin with 15 discovery calls. Shortlist two or three agencies whose strongest work matches your immediate constraint, budget, industry, and internal capacity.
Bring the same questions to every call. Ask who will do the work, what the first 90 days include, which client result is most comparable to yours, what your team must implement, and how success will be measured. You should leave the process able to explain why one firm fits—not merely which presentation looked best.
