Geology and First Page Sage both target the same problem (showing up in AI answers for B2B buyers) but they sell different things. First Page Sage is a managed GEO and SEO agency, positioning itself as a top-tier service for enterprise B2B and professional services. Geology is a B2B SaaS platform that tracks brand presence across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews and ships fixes through an agentic optimization layer. Pick First Page Sage when you want a full agency to run the program. Pick Geology when you want to own the program and use software to do the heavy lifting.

What First Page Sage does
First Page Sage is a US agency that has rebranded heavily around GEO and AI search, calling itself a top-tier provider for enterprise B2B and professional services. As stated on firstpagesage.com, the team runs full-service engagements: strategy, content production, on-page optimization, technical SEO, and reporting on AI visibility alongside traditional rankings. The agency publishes original research on click-through rates and conversion benchmarks, which gets cited widely. Typical clients are mid-to-large B2B companies that want a single partner to run their organic and AI search program end to end, with content output and reporting handled by the agency team. Engagements are retainer-based and built around a long horizon (six to twelve months minimum).
What Geology does differently
Geology gives you the measurement and execution loop that an agency runs internally, packaged as software you operate. The platform tracks brand presence across the five major AI surfaces, then connects that measurement to execution: page audits flag the pages an AI is misreading, prompt management captures the queries your buyers actually run, the content workspace converts gaps into briefs your writers can ship, and an agentic optimization layer applies common fixes (schema, FAQ structure, internal linking) without an account manager in the loop. The result is faster cycles. Where a managed retainer reports monthly and ships quarterly, Geology lets your team re-measure and re-ship in days. The work is more thorough too, because every page is audited every cycle instead of sampling.
Pricing
First Page Sage runs monthly retainers with custom quotes; for serious B2B engagements, expect mid-five figures per month and a year-long commitment. Geology is sold on a transparent SaaS subscription with public tiers, sized for B2B and mid-market teams. For a team that already has writers and developers, Geology lands at a fraction of an agency retainer.
When First Page Sage wins
If you have no in-house SEO or content team and you want a single retainer that produces strategy, articles, and reporting without internal load, First Page Sage is a fair pick. The case studies on enterprise B2B and professional services are real, and the original CTR research is well-known.
When Geology wins
If your team has writers and developers and you want to own the GEO program rather than rent it, Geology is the better fit. You get the cross-platform measurement, the briefs, and an agentic execution layer that ships fixes weekly. The cost and speed advantages over an agency retainer compound across a year.
