Pricing for B2B SEO retainers ranges from $2,500 to more than $50,000 a month, and the difference is not always quality. The harder problem is finding an agency that understands long sales cycles, technical buyers, and multi-touch decision-making. 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.
This list covers 18 B2B SEO agencies that work on complex, considered markets. Each has a different strength: demand generation, content-led SEO, or technical audits at scale. Use the summary below to narrow down which one fits your business, then read the full profiles for pricing, team structure, and engagement models.
Summary
- Full-stack growth: NEWMEDIA.COM, Directive Consulting, Powered by Search, Kalungi, and Foundgrove bundle search with web development, paid media, conversion optimization (CRO), or go-to-market work.
- B2B and SaaS search specialists: B2BSEO.io, Skale, SimpleTiger, MADX Digital, Growfusely, and Breaking B2B run technical SEO, content, links, and AI search as one program.
- Content-led: Grow and Convert, Omniscient Digital, Animalz, Foundation Marketing, and Loudspeaker Marketing start from content strategy and editorial.
- Technical SEO for large or messy sites: Onely and iPullRank.
- Pricing varies a lot. Published monthly rates run from $2,500 (Foundgrove) to more than $50,000 (Kalungi), and several agencies only quote custom pricing.
- Judge on pipeline, not traffic. Ask for a case study that ties one page to leads, ask who will actually work on your account, and be wary of guaranteed rankings or long contracts before you have seen a deliverable.

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.

B2B experience: Reports generating more than 600 trials and demos a month for Smartlook. 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: 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.
Best fit: Growth-stage B2B SaaS and AI companies that want one specialized team for SEO, content, authority building, and AI visibility.
B2B experience: Reports increasing Centerbase's top-three rankings by 193%. Work for Segment grew traffic to integration pages by 127% within two months, and one primary integration page grew by 597%.

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.
Best fit: Established B2B SaaS, cybersecurity, fintech, and healthtech companies with product-market fit and lean internal marketing teams.
B2B experience: Reports working with more than 200 B2B companies. That experience covers software categories with long sales cycles and several decision-makers.

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.

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

Loudspeaker Marketing builds organic growth programs for B2B SaaS startups and scaleups.

B2B experience: 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 large language model (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 is 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.
Best fit: B2B SaaS and service companies in fintech, healthtech, martech, logistics, financial services, and construction.

16. Onely
Onely is one of the more technical agencies on this list. The team takes on problems that typical content agencies cannot 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.
Best fit: Enterprise B2B and SaaS companies with large websites, JavaScript frameworks, international domains, headless platforms, or serious crawl and indexation problems.
B2B experience: 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.

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.
Best fit: Enterprise B2B companies with complex websites, several business units, large content libraries, or advanced AI search requirements.

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.
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: 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.
SEO team: Every account gets a US-based senior strategist. Foundgrove says it does not 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. 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. 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 did not 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, including site structure, page speed, and indexing, so the content has a real chance to rank once published.
Reporting matters too. A strong partner shows 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 is 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 do not 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 cannot 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 are 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 is 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 is 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 cannot produce this usually do not track anything past traffic, which means they do not know whether their work drives revenue. Also ask how they define qualified. A demo request from a student researching a class project is not 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 is 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 have 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 is good at.
Look at how each agency talks about failure. Every agency has clients who did not 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 would approach your specific market on the first call. The quality of that thinking often tells you more than any past client logo.
