B2B SaaS SEO agency with GEO, AEO & LLM SEO practice · London, UK
Revenue-focused B2B search agency combining SEO, GEO, bottom-of-funnel content, technical optimization, and brand-mention outreach to generate qualified demos from Google and AI search.
Founded by Sam Dunning in 2020, initially as a broader B2B marketing platform covering content, sales, interviews, podcasting, and web design before sharpening into B2B SEO specifically. As AI-assisted search grew, the agency expanded into GEO, AEO, and LLM SEO — a shorter, more compressed timeline than most full-service peers in this set, since the whole company is only about five years old.
Best for: B2B SaaS companies wanting an aggressive, bottom-of-funnel SEO and GEO program tied to demos and qualified pipeline.
Breaking B2B has the deepest bench of named case studies of any agency in this set — VerifyTreatment, Proposify, RB2B, MarqVision, Fibbler, Kubaru, and The B2B Playbook, each with specific, concrete numbers: demo counts, traffic percentages, ranking positions, even deals closed. Several results are specifically AI-related, like VerifyTreatment's prospects citing ChatGPT and Google AI Overviews as their discovery source. Pricing is also unusually public: four named tiers from $4,000 to $20,000+/month, a 90-day sprint contract with no annual lock-in, and an explicit growth guarantee. The catch, and it's a real one: there's no Clutch or G2 profile anywhere, so every number here is self-published, and Breaking B2B's own "best agency" roundup articles rank itself first — the same self-promotional pattern this whole site exists to flag, and the second agency in our research (after SeoProfy) doing exactly this.
Good fit if
Less so if
Source: agency's own published methodology pages.
Sources: agency's own published case studies, Clutch (searched, not found), G2 (searched, not found).
Publishes extensive educational content — a B2B marketing podcast, newsletter, playbooks, and implementation guides — plus practical observations from its own AI-search testing, including shifts in Reddit's value as an AI citation source. No large-scale proprietary benchmark or annual research report was found.
Disclosure flag: Breaking B2B publishes its own "best AI SEO agency" style roundup articles and ranks itself first in several of them. That doesn't make its case studies untrue, but the ranking itself carries no independent weight — it's the same agency being evaluated doing the evaluating, and it's worth knowing this is the second agency in our research (after SeoProfy) doing exactly this.
Reported that prospects were explicitly naming ChatGPT and Google AI Overviews when asked how they found the company, with incoming demos becoming increasingly enterprise-focused.
