The Top Gemini SEO Agency for B2B: We review 7 top contenders in 2026

Quick summary

To find the best Gemini SEO agency for B2B, we weighed seven contenders, Breaking B2B, iPullRank, Onely, Go Fish Digital, Single Grain, Siege Media, and NoGood, on three things: coverage across AI Overviews, AI Mode, and Workspace, the methodology underneath the service page, and verifiable client wins.

What is a Gemini SEO agency?

A Gemini SEO agency works to get your brand named when Gemini provides an answer about your category. The work includes the three places your buyer sees Gemini: AI Overviews on Google search, the AI Mode tab, and Gemini within Workspace. 

Most agencies treat one of these as the entire problem and call it SEO for Gemini. The good ones are building for all four, because the same buyer will move between them in one afternoon of research.

Why listen to us?

We run Breaking B2B, a B2B SaaS SEO and AI search agency, and the work we do for clients is the same work we apply to our own brand. We took RB2B  to $8.7M ARR with our engine, and they now rank #1 on Google organic and get cited in AI search for

“Leadfeeder alternatives.” Proposify saw demos rise 115% and AI search visitors climb 91% on the same retainer, with citations across AI search surfaces for “best proposal software.”

Why hire a Gemini SEO agency for your B2B company?

Most B2B SaaS teams end up bringing in outside help instead of trying to handle Gemini internally, and the reasons usually come down to three things.

1. Covering multiple surfaces is more work than it looks: The same model that powers the AI Overview over normal search, that powers the AI Mode tab, that lives in your buyer’s Workspace docs. Monitoring your brand across all of these and refreshing content for each is a full-time motion that most in-house teams can’t keep running past the first quarter.
2. Earned mentions need a real outreach engine: Gemini decides which vendors to name based on outside sources like G2, Capterra, industry roundups, and high-authority listicles. Getting into those requires a slower, more relational sort of work than most marketing teams have the bandwidth to build from scratch.
3. Two retainers is not the way to go: At Breaking B2B, we run both SEO and Gemini work on a single retainer because splitting them across separate agencies usually doubles your reporting overhead and dilutes the budget across two strategies that should be one.
