18 B2B SEO Agencies Worth a Closer Look in 2026

Finding a B2B SEO agency that understands long sales cycles, technical buyers, and multi-touch decision-making is a different job from finding a generic SEO provider. Most agencies optimize for quick wins and vanity traffic, and that approach falls apart when your buyer takes months to convert and pulls in five stakeholders along the way.

We reviewed 18 B2B SEO agencies that consistently deliver results for companies selling into complex, considered markets. Each one has a different strength, whether that’s demand generation, content-led SEO, or technical audits at scale.

Below is what each agency does best, who they work with, and how to figure out which one fits your business.

1. NEWMEDIA.COM

NEWMEDIA.COM approaches B2B SEO as part of a broader growth program. Its work can span technical SEO, content, link building, AI search, and website development, with strategy shaped around a company’s sales goals.

Agency profile

• Best fit: B2B companies that want SEO alongside services such as web development, paid media, PR, or conversion optimization. The agency’s range may be useful for companies with complex websites or multiple growth priorities.
• B2B experience: NEWMEDIA.COM offers dedicated B2B SEO services for companies selling SaaS, enterprise services, and other business solutions. It says its strategy aligns keywords, pages, and links with sales goals. Its published case studies include a B2B ecommerce company, though prospective clients should ask for examples from their own industry and business model.
• SEO team: The agency describes a multidisciplinary team that works across SEO, content, web design and development, paid media, and conversion optimization. Ask who will lead the SEO strategy and which specialists will handle the day-to-day work.
• Engagement model: NEWMEDIA.COM builds custom programs. Its B2B SEO offering is designed to connect organic search with sales goals, while its broader services include technical SEO, content, link building, AI search optimization, PR, and web work. Confirm which of these are included in your proposal and how the agency will report progress.
• Typical investment: NEWMEDIA.COM doesn’t publish standard B2B SEO pricing. It offers custom proposals, so ask for a clear breakdown of the monthly fee, deliverables, content and link-building costs, and any additional services.

2. B2BSEO.io

B2BSEO.io is a specialist B2B SEO agency for companies that want search to reach buyers while they’re researching, comparing vendors, and building a shortlist. The agency’s work covers Google and AI search, with a focus on commercial pages, SaaS content, and authority building.

Agency profile

• Best fit: B2B SaaS and service companies with a defined market, a considered sales process, and a need to connect organic visibility with qualified leads or pipeline.
• B2B experience: The agency publishes case studies across B2B SaaS, healthcare, industrial, and professional services. Its SaaS examples include FeedBird and TrackDesk, and one published case study describes growing a client’s blog traffic from over 80,000 to more than 250,000 monthly organic visits over a year.
• SEO team: B2BSEO.io is led by founder Ashot Nanayan and offers strategy and execution across technical SEO, content, on-page optimization, link building, and AI search visibility. Before signing, ask who will own each part of the work and how much direct access you’ll have to the people doing it.
• Engagement model: The agency offers ongoing SEO programs as well as focused services such as audits and link building. Its positioning centers on aligning keyword and content priorities with the buyer journey, then tracking outcomes beyond rankings and visits.
• Typical investment: Custom pricing.

3. Grow and Convert

Grow and Convert takes a narrower approach than most content agencies. Founders Benji Hyam and Devesh Khanal built the agency around Pain Point SEO, which prioritizes keywords tied to real customer problems and buying intent.

The team also tracks conversions at the article level. That lets B2B companies see which pages produce demos, trials, and leads, instead of judging content on traffic alone.

Agency profile

• Best fit: B2B SaaS and service companies with clear product-market fit, well-defined customer pain points, and access to internal experts.
• B2B experience: Grow and Convert reports generating more than 600 trials and demos a month for Smartlook. Its work for Leadfeeder produced more than 215 sign-ups and 21,000 organic visitors a month.
• SEO team: Around 20 strategists and writers across the United States and Europe. Clients work directly with content strategists rather than going through a separate account manager.
• Engagement model: Fully managed content programs covering research, SEO and GEO (generative engine optimization, the work of getting cited in AI answers) strategy, writing, link acquisition, and conversion reporting.
• Typical investment: From $10,000 a month. No long-term contract is required.

4. Skale

Skale was built by SaaS growth operators rather than generalist agency marketers. Co-founder Jake Stainer previously grew Typeform’s SEO channel from zero to more than 30,000 monthly sign-ups.

Co-founder Italo Viale brought experience from more than 120 SEO accounts. That background shows in an approach aimed at sign-ups and pipeline rather than ranking reports.

Agency profile

• Best fit: Funded and growth-stage B2B SaaS companies that want technical SEO, content, link building, and AI search run through one program.
• B2B experience: Skale has worked with more than 100 SaaS and technology companies, including Attest, Aircall, Perkbox, Slite, and Maze. The agency reports increasing Attest’s product sign-ups 8.5 times.
• SEO team: A global team of nearly 40 specialists across technical SEO, content, digital PR, link building, conversion optimization, and GEO.
• Engagement model: Full-service retainers, plus separate engagements for content, links, technical SEO, or website migrations.
• Typical investment: Skale’s UK pricing page lists SEO services from £4,000 a month.

5. Omniscient Digital

Omniscient Digital brings a lot of in-house B2B software experience to agency work. Co-founders Alex Birkett, Allie Konchar, and David Ly Khim previously held growth or content roles at HubSpot, Shopify, Workato, and People.ai.

The team treats SEO as an organic growth channel tied to pipeline. It also covers AI search, content strategy, technical SEO, digital PR, and conversion optimization.

Agency profile

• Best fit: Established B2B software companies with internal marketing support and enough subject-matter expertise to produce differentiated content.
• B2B experience: Clients include SAP, Jasper, Order.co, Asana, Loom, and Hotjar. Omniscient Digital reports generating $4 million in blog-attributed annual recurring revenue for Jasper and $400,000 in qualified pipeline for Teambridge.
• SEO team: Senior strategists work alongside technical SEO specialists, editors, writers, conversion experts, and digital PR people.
• Engagement model: Full-service monthly programs, or standalone SEO and content strategy projects.
• Typical investment: Full-service engagements start at $10,000 a month. Strategy projects start at $15,000.

6. Directive Consulting

Directive Consulting puts SEO inside a wider B2B customer-generation program. The team combines technical SEO, content, paid media, conversion optimization, and analytics. That model suits companies that want search data tied to opportunities and revenue across the full funnel.

Agency profile

• Best fit: Mid-market and enterprise B2B SaaS, cybersecurity, fintech, and technology companies with mature demand-generation teams.
• B2B experience: Directive Consulting reports increasing Inscribe’s keyword rankings by 237% and organic traffic by 32%. Its AxisCare campaign produced 200% more demos and brought in new sales-qualified leads through AI search.
• SEO team: SEO strategists are backed by content, analytics, paid media, design, and conversion specialists.
• Engagement model: Custom retainers that can combine SEO with paid acquisition, CRO, content, and performance analytics.
• Typical investment: Custom pricing.

7. SimpleTiger

SimpleTiger works only on SaaS SEO. The agency has spent more than 15 years with software companies and now combines traditional search with GEO, AEO (answer engine optimization), content, link building, paid media, and Webflow support.

That narrow focus means the team knows product-led funnels, integration pages, and comparison content, and can tell informational traffic apart from qualified software buyers.

Agency profile

• Best fit: Growth-stage B2B SaaS and AI companies that want one specialized team for SEO, content, authority building, and AI visibility.
• B2B experience: SimpleTiger reports increasing Centerbase’s top-three rankings by 193%. Its work for Segment grew traffic to integration pages by 127% within two months, and one primary integration page grew by 597%.
• SEO team: A boutique team covering technical SEO, content strategy, writing, link building, paid media, Webflow, and account management.
• Engagement model: Customized SEO and GEO packages with shared reporting, Slack access, and a dedicated account manager.
• Typical investment: Custom pricing based on the company’s growth stage and scope.

8. MADX Digital

MADX Digital specializes in search for SaaS and technology companies. The team covers SEO, content, digital PR, backlinks, development, analytics, and project management.

The agency also folds GEO into its Google SEO work instead of selling AI visibility as a separate add-on. Its technical work includes crawlability, indexation, internal linking, site architecture, and performance.

Agency profile

• Best fit: Funded B2B SaaS, fintech, AI, and enterprise software companies that need technical SEO and authority building under one program.
• B2B experience: MADX Digital reports working with more than 50 SaaS brands. Its Thunes campaign took top-three rankings from 32 to 372 and raised estimated organic traffic value by 520%.
• SEO team: SEO managers, technical specialists, content managers, link builders, analysts, developers, and quality-assurance editors.
• Engagement model: Managed SEO programs, or separate projects for strategy, content, links, and digital PR.
• Typical investment: Plans start at $3,500 a month. Growth plans start at $5,500 and scale plans at $9,500.

9. Powered by Search

Powered by Search has worked with B2B SaaS and technology companies since 2009. Its approach combines SEO, GEO, content, digital PR, conversion optimization, and revenue operations.

The agency puts unusual weight on positioning and pipeline attribution. That makes it more relevant for companies whose search problem goes beyond rankings, into weak messaging or poor lead tracking.

Agency profile

• Best fit: Established B2B SaaS, cybersecurity, fintech, and healthtech companies with product-market fit and lean internal marketing teams.
• B2B experience: Powered by Search reports working with more than 200 B2B companies. That experience covers software categories with long sales cycles and several decision-makers.
• SEO team: A distributed team across more than eight countries. Depending on the plan, clients work with one SEO strategist or an embedded group covering SEO, content, digital PR, CRO, and RevOps.
• Engagement model: Consulting, implementation, and full promotion programs.
• Typical investment: Monthly plans start at $9,000. Quarterly billing starts at $7,500 a month.

Its clients include well-known technology brands such as Amazon, Airtable, Atlassian, Auth0, Intercom, Ramp, and UiPath.

• Best fit: Established B2B SaaS companies that need strong editorial content, executive thought leadership, SEO, and AEO.

• SEO team: Content strategists, editors, writers, AI search specialists, and marketing operations staff.
• Engagement model: Ongoing content and organic growth programs covering strategy, production, refreshes, content engineering, and AI citation tracking.
• Typical investment: Custom pricing.

11. Foundation Marketing

Foundation Marketing pairs B2B content strategy with distribution. The team covers SEO, AEO, technical audits, digital PR, Reddit, YouTube, content repurposing, and analytics. That breadth is useful when publishing more content has stopped producing growth.

Agency profile

• Best fit: Established B2B SaaS companies with valuable content libraries that need stronger SEO, refreshes, distribution, and authority.
• B2B experience: Client work includes brands such as Canva and Procore. Foundation Marketing also reports growing traffic for an event software company by 156% after refreshing more than 100 posts and producing 50 to 70 new assets.
• SEO team: A global team of strategists, technical SEO specialists, writers, distribution experts, analysts, and digital PR people.
• Engagement model: Strategy projects, audits, and ongoing implementation programs.
• Typical investment: Custom pricing.

12. Kalungi

Kalungi is a full-service B2B SaaS marketing agency, not an SEO-only shop. Co-founder Stijn Hendrikse developed the T2D3 framework around the growth stages SaaS companies move through after finding product-market fit.

SEO sits inside a broader go-to-market system that includes positioning, content, paid acquisition, ABM, design, CRM, and marketing operations.

Agency profile

• Best fit: Post-product-market-fit B2B SaaS companies between roughly $5 million and $50 million in annual recurring revenue.

13. Growfusely

Growfusely works only with B2B SaaS and AI-native companies. Founder Pratik Dholakiya leads search strategy, while specialists handle technical SEO, content, digital PR, authority building, and AI citations.

The work goes past publishing articles. The team looks at site architecture, entity clarity, structured data, LLM crawler access, and the third-party sources that shape AI recommendations.

Agency profile

• Best fit: B2B SaaS companies in cybersecurity, fintech, developer tools, compliance, and AI. Growfusely makes particular sense for teams that want SEO and AI search managed in the same program.
• B2B experience: The portfolio includes more than 55 SaaS and AI-native brands such as Wix, Whatfix, FreshBooks, Sprinto, JetOctopus, and Document360. Growfusely reports 217% qualified traffic growth for Mind the Graph, and its work for JetOctopus doubled organic traffic within six months.

14. Loudspeaker Marketing

Loudspeaker Marketing builds organic growth programs for B2B SaaS startups and scaleups. The team combines content strategy with programmatic SEO, conversion tracking, GEO, AEO, and custom AI workflows. They use AI to speed up research and intent analysis, but experienced operators still run the program.

Agency profile

• Best fit: Fast-moving B2B SaaS and AI companies that need content clusters, programmatic SEO, and AI search visibility without building a large internal team.
• B2B experience: Loudspeaker Marketing reports working with more than 70 companies. Client references include 11x, Rivo, Archive, Landbase, Ark7, and Reddit’s small-business growth team. Landbase reported 42% more organic visitors and 66% more LLM sessions after the agency published 79 articles in two months.
• SEO team: Accounts are run by growth operators and strategists who have worked inside startup marketing teams. The agency presents itself as an extension of the client’s team rather than a separate content vendor.
• Engagement model: Flexible organic growth programs covering strategy, content production, technical improvements, programmatic SEO, and conversion tracking.
• Typical investment: Custom pricing.

15. Breaking B2B

Breaking B2B is a specialist SEO and AI search agency for B2B companies. It’s built around one simple position: search should generate pipeline, not vanity traffic.

The team starts with commercial pages and bottom-of-funnel opportunities before moving on to broader informational topics. Technical SEO, authority building, conversion improvements, GEO, and AEO all sit inside the same program.

Agency profile

• Best fit: B2B SaaS and service companies in fintech, healthtech, martech, logistics, financial services, and construction.
• B2B experience: More than 50 B2B companies have worked with Breaking B2B. The agency reports helping VerifyTreatment grow from five to 32 demos a month. RB2B increased non-branded organic traffic by 77%, and Chattermill raised its AI search mention rate from 20% to 80%.

• Engagement model: Six- or 12-month programs covering technical SEO, commercial content, link building, AI search, and pipeline reporting.
• Typical investment: Tailored plans start at $4,000 a month. Standard growth programs start at $5,500 a month.

16. Onely

Onely is one of the more technical agencies on this list. The team takes on problems that typical content agencies can’t solve: rendering failures, wasted crawl budget, server-log analysis, headless architecture, structured data, international SEO, and whether AI search can extract your content at all.

Agency profile

• Best fit: Enterprise B2B and SaaS companies with large websites, JavaScript frameworks, international domains, headless platforms, or serious crawl and indexation problems.
• B2B experience: Onely has worked with G2, 123FormBuilder, Europejski Fundusz Leasingowy, and other companies with technically complex websites. Its Stratos Jets project produced a reported 195% increase in organic traffic and a 1,931% increase in search visibility.
• SEO team: Technical SEO specialists who can work with server logs, JavaScript, structured data, site architecture, and your development team.
• Engagement model: Technical audits, strategy projects, implementation support, traffic-drop recovery, and ongoing consulting.

17. iPullRank

iPullRank works at the technical end of enterprise search. Its framework brings technical SEO, information retrieval, content strategy, digital PR, audience research, and AI search into one system.

The team can handle large websites where rendering, internal linking, structured data, site migrations, and content quality cause problems at scale.

Agency profile

• Best fit: Enterprise B2B companies with complex websites, several business units, large content libraries, or advanced AI search requirements.
• B2B experience: Founder Mike King has advised brands such as SAP, American Express, and HSBC. iPullRank reports generating more than $5 billion in organic search results across its client work.

• Typical investment: Custom pricing. AI Search Strategy programs start at $15,000 a month.

18. Foundgrove

Foundgrove is a US-based agency whose core market is service businesses, though it also promotes B2B SEO for SaaS companies and manufacturers. It combines technical SEO, local search, content, link building, GEO, AEO, paid media, and conversion-focused web development.

Its model is built around booked calls and CRM revenue rather than rankings alone.

Agency profile

• Best fit: B2B service companies, manufacturers, multi-location businesses, and smaller SaaS companies that need search, paid media, and website improvements from one partner.
• B2B experience: Foundgrove publishes a dedicated B2B program for SaaS companies and manufacturers. One anonymized project involved a dental technology manufacturer selling technical products to clinicians. Its public B2B case-study library is still smaller than those of the more established agencies on this list, though.
• SEO team: Every account gets a US-based senior strategist. Foundgrove says it doesn’t use offshore teams or white-label resellers.
• Engagement model: Month-to-month programs combining SEO, GEO, AEO, paid advertising, and conversion-focused web development.
• Typical investment: From $2,500 a month, with no long-term contract.

How we picked these B2B SEO agencies

We started with a list of more than 40 agencies that claim B2B SEO experience, then narrowed it down with a few criteria. First, we looked for published case studies that tie SEO work to pipeline or revenue, not just traffic charts. Agencies that only showed ranking screenshots got cut early.

We also weighed how long each agency has worked in B2B specifically, since sales cycles, buyer research habits, and content needs differ a lot from B2C or ecommerce work. Agencies that spread their focus across too many verticals without a clear B2B specialty didn’t make the final cut.

Client reviews on Clutch and G2 counted too, along with how open each agency is about pricing and process on its own site. The 18 agencies above made it through all three filters.

What a strong B2B SEO partner should do

A strong B2B SEO partner starts with your buyer, not your keyword list. That means researching who makes the purchase decision, what they search for at each stage, and which objections come up before a deal closes.

From there, a good partner builds content around your sales cycle instead of generic top-of-funnel topics. They should also handle the technical side (site structure, page speed, and indexing) so the content has a real chance to rank once it’s published.

Reporting matters too. A strong partner shows you which pages drive traffic that turns into leads, not just which pages get the most visits. And they should be honest about timelines. B2B SEO takes months to show results, and any partner promising overnight wins is setting you up for disappointment.

How to choose an agency that understands your sales cycle

Start by asking how the agency researches your buyers before writing a single piece of content. Do they talk to your sales team, review past deals, and look at what your best customers searched for before they became customers? If the answer is vague, they probably treat every client the same way.

Ask for examples of content the agency wrote for a company with a similarly long or complex sales cycle. A blog post that works for a $50-a-month subscription tool reads very differently from one written for a $50,000 annual contract that needs sign-off from procurement, legal, and finance.

It’s also worth checking whether the agency understands the difference between top-of-funnel awareness content and bottom-of-funnel content built to move a deal forward. Agencies that only produce one kind usually don’t grasp how B2B buying works.

Questions to ask before you sign an SEO retainer

Before signing anything, ask the agency how they define success. If they only talk about rankings and traffic, keep pushing until they connect the work to pipeline and revenue.

A few other questions worth asking directly:

• Who will work on our account, and will we have access to senior strategists or mostly junior staff?
• What do the first 90 days look like, and what should we expect to see by month three?
• How do you handle content that touches technical or regulated topics?
• What happens if our internal team can’t turn around approvals or dev requests quickly?
• Can we see reporting examples from a client in our industry?

A vague answer to any of these is worth a second look before you commit budget.

What B2B SEO costs, and what changes the price

Most B2B SEO retainers run between $3,000 and $20,000 a month, with enterprise engagements going higher. A few factors push the price up or down.

Scope is the biggest driver. An agency handling technical SEO, content production, and link building charges more than one focused only on content. Industry complexity matters too: fintech, healthcare, and legal content often needs subject-matter review, which adds cost.

Team structure also plays a role. Agencies that put senior strategists on every account tend to charge more than those relying on junior writers with light oversight. And keyword difficulty in your market affects how much work it takes to rank at all, which shows up in the quote.

When to hire a B2B SEO agency instead of building in-house

Hiring in-house makes sense once you have a steady budget for a full team: a strategist, a writer or two, and someone handling technical SEO. Below that threshold, you’re usually paying more for less coverage than an agency gives you.

An agency also makes sense when you need specialized skills fast, like digital PR relationships or a technical audit for a complex site migration. Building that expertise in-house takes months, sometimes years.

In-house teams tend to win when your product is niche enough that outside writers struggle to produce credible content without heavy internal review on every piece. If your team is already correcting most of what an agency sends over, that’s a signal to bring the work in-house.

How to tell whether an agency can drive qualified leads

Traffic and rankings are the easy part to show. Qualified leads are harder, and that’s where most agencies get vague. Ask for a case study that shows the full path: keyword targeted, content published, ranking achieved, and the leads or pipeline that came from that specific page.

Agencies that can’t produce this usually don’t track anything past traffic, which means they don’t know whether their work drives revenue. Also ask how they define “qualified”. A demo request from a student researching a class project isn’t the same as one from a director at a company that fits your ideal customer profile.

If an agency can walk you through its targeting logic, keyword by keyword, and tie it back to your sales team’s definition of a good lead, that’s a strong sign it understands B2B growth beyond surface metrics.

Red flags to watch for in an agency pitch

A few warning signs to look for before you sign:

• Promises of guaranteed rankings, or a specific position on Google within a fixed timeframe
• Case studies that show traffic growth but never mention leads, pipeline, or revenue
• Heavy reliance on AI-generated content with little or no editorial review
• Vague answers about who will work on your account
• Pressure to sign a long-term contract before you’ve seen a single deliverable
• No clear process for researching your buyers and sales cycle before writing content

None of these alone is disqualifying, but two or three together usually mean the agency is optimizing for closing your deal, not for running your campaign.

How to compare agencies beyond their case studies

Case studies are curated by design, so they only tell part of the story. Ask each agency for a reference client of a similar industry or company size, and actually call them. Ask that reference what the agency is bad at, not just what it’s good at.

Look at how each agency talks about failure. Every agency has clients who didn’t see results, and the ones worth hiring can explain why, honestly, without blaming the client.

It also helps to compare how each agency thinks, not just what it has done. Ask them to walk through how they’d approach your specific market on the first call. The quality of that thinking often tells you more than any past client logo.
