Best B2B SEO Agencies in 2026: Who the Ranked Lists Name Most

The best B2B SEO agencies in 2026 by list count are the seven named on at least three of the nine lists, shown here with how each describes itself and what it publishes about price:

Nine more agencies appear on two lists each: First Page Sage, iPullRank, Omnius, Onely, OuterBox, SimpleTiger, Ten Speed, Victorious and Virayo. Across all nine lists, 64 different agencies are named, and 45 of them are named by just one list other than their own. Agreement is thin outside the top seven, which is the most useful thing the count shows: a name on one list is one publisher's opinion.

The descriptions and prices come from each agency's own homepage and pricing page on November 5, 2026. Grow and Convert's count leaves out its own list, as does First Page Sage's.

No B2B SEO agency is the best for every company, and the lists themselves label the leaders by the kind of work they suit. Three of the nine lists, Crowdo's, Dageno's and Optimist's, give every entry a "best for" label, and those labels are a better guide than the rank:

• Omniscient Digital: B2B SaaS content-led growth (Crowdo), or B2B SaaS companies turning an existing content program into a pipeline channel (Optimist).
• Siege Media: content and digital PR at scale (Crowdo), content-driven link building (Dageno), or content production and link acquisition for B2B and B2C companies (Optimist).
• Directive Consulting: enterprise B2B pipeline programs (Crowdo), SaaS and tech performance marketing (Dageno), or enterprise SaaS companies with both paid and organic budgets (Optimist).
• Grow and Convert: bottom-of-funnel, pain-point content that converts (Crowdo), or companies that want content as their main pipeline driver (Optimist).
• Powered by Search: B2B SaaS companies with contract values above $50,000 and sales cycles of six months or more (Optimist).
• RevenueZen: B2B SaaS organic growth (Dageno), or interview-led content for B2B SaaS and service companies (Optimist).

So the first question is what you need most. A company that needs content produced at volume, one that needs links and PR, and one that needs SEO tied to a paid and pipeline program will each get a different answer from the same seven names. Price narrows it again: two of the seven publish entry prices of $3,000 and $7,500 a month, while one starts at $120,000 a year.

For SaaS companies, the best B2B SEO agencies are easier to find with a SaaS search, because Google's first page for "best B2B SEO agencies for SaaS" is mostly lists written about software companies.

On November 5, 2026 that page opened with Breaking B2B's 18 SaaS SEO agencies, then Grow and Convert's 11 B2B SaaS agencies and Scalerrs' 16, with SEOProfy's 12 further down. Of the nine lists we counted, only Grow and Convert's is titled for B2B SaaS, though Grizzle's says most of its picks focus on SaaS. Among the seven most-named agencies, Skale's homepage presents it as a SaaS specialist and Omniscient Digital's says it works with B2B software businesses; the other five describe a wider client base, so ask each one how many of its current clients sell software, and at what deal size.

B2B SEO agencies charge from $3,000 a month to $21,600 a month and up, going by the three of the seven most-named agencies that publish a price on their own site:

• RevenueZen lists six monthly tiers: $3,000, $5,000, $7,000, $10,000, $12,000 and $15,000.
• Powered by Search prices its SEO and LLM ranking plans from $7,500, $12,000 and $18,000 a month billed quarterly, or $9,000, $14,400 and $21,600 billed monthly.
• Omniscient Digital says full-service engagements start at $120,000 a year, about $10,000 a month.

The other four, Siege Media, Directive Consulting, Grow and Convert and Skale, publish no SEO price, so expect a quote after a call. Most of these plans now include some AI search work, and if that is what you are buying, our breakdown of what AI SEO costs covers audits, tools and retainers in the same terms.

Most best B2B SEO agency lists rank their own agency first because an agency publishes the list to win clients, and seven of the nine lists we counted put their publisher at number one: Grizzle, Grow and Convert, First Page Sage, Fame, Optimist, POLARIS and Crowdo.

That doesn't make the other entries worthless, but it changes how to read them. Google's guidance on review pages asks anyone who calls something the best overall, or the best for a purpose, to include why, with first-hand supporting evidence. Few of these lists show that kind of evidence for the agencies they rank, and none can be neutral about their own entry. Counting across lists cancels some of that out, which is why the table above leaves each agency's own list out of its total.

The two lists that don't rank their publisher come from Dageno, an AI visibility software company that also sells managed GEO and AEO services, and Sermondo, a B2B marketing site whose first pick, HigherUp Digital, is credited in its footer with the site's web design. We publish the same kind of comparison for AI SEO firms, and our review of 18 AI SEO agencies ranks no one, including us.

To choose a B2B SEO agency, shortlist two or three names from the count above, then check each one against five things you can confirm before a sales call:

• Fit. Its own site should say what kind of company it works for. If you sell software, ask how many current clients do too.
• Price. Three of the seven most-named publish one. If an agency won't give a range, budget for a quote after the call.
• Proof. Ask for results from a company like yours, with the dates, the metric and how it was measured.
• AI search. Five of the seven most-named agencies now put GEO or AI search in their homepage title or headline. Ask how they measure it: which buyer questions, on which AI tools, and how many runs of each.
• The first 90 days. Get in writing what gets measured at the start, what gets done, and what gets measured again at the end.

High Salience fits in this list as a disclosed outsider: we are a B2B SEO and AI search agency, none of the nine lists names us, and we left ourselves out of the count.

Our work covers Google rankings and AI answers together, measured question by question across a category, for B2B software companies and other category leaders. Engagements start at $7,500 a month after a $750 audit, and the method is public on our B2B SaaS SEO agency page. We have no client case files to publish yet, so judge us on our published research, not on a list.

We counted the nine lists that Google showed on the first page of its US results for "best B2B SEO agencies 2026" and "best B2B SEO agencies" on November 5, 2026. Each search returned eight organic results. We left out a Reddit thread, the GoodFirms directory, one agency's own service page and Rock The Rankings' hub page, which names no agencies itself and links to 24 separate lists.

The lists, by publisher and size: Grizzle (9), Grow and Convert (11, B2B SaaS), First Page Sage (7), Sermondo (11), Fame (8), Dageno (15), Optimist (13), POLARIS (10) and Crowdo (12), 96 entries in all. We recorded each list's numbered or headed agencies as named on the page and matched spelling variants such as Skale and Skale.so. An agency's own list doesn't count toward its total. The same day, we asked ChatGPT and Claude about B2B SEO agencies 10 times, and every answer searched the web for the best B2B SEO agencies of 2026 before it named any. Lists like these are where AI answers get their names: Grow and Convert's and Grizzle's were among the pages ChatGPT or Claude cited.

These best B2B SEO agencies FAQs cover what a B2B SEO agency does, AI search, how far to trust the lists, and whether to hire one.

What is a B2B SEO agency?

A B2B SEO agency is an SEO firm that works for companies selling to other businesses, where a sale takes months, involves several people and starts with research. The work is the same as other SEO, but the pages target fewer, higher-value searches, and success is measured in qualified pipeline rather than traffic.

Do B2B SEO agencies also do GEO and AEO?

Many B2B SEO agencies now sell GEO or AEO work: five of the seven most-named agencies in our count put GEO or AI search in their homepage title or headline. What that work includes varies a lot, so read our checklist of what AI SEO services include before you compare proposals.

Are best B2B SEO agency lists reliable?

Best B2B SEO agency lists are reliable as a shortlist, not as a ranking. Seven of the nine lists we counted put their own agency first, so trust the names that several publishers agree on, and check each agency's fit, price and proof yourself.

Is hiring a B2B SEO agency worth it?

Hiring a B2B SEO agency is worth it when organic search is a channel your buyers use and your team can't staff the work. Google's advice on hiring an SEO suggests asking for examples of previous work, expected results and timelines, and how success is measured, and warns that no one can guarantee a number one ranking.
