Geology and First Page Sage both target the same problem (showing up in Google and AI answers for B2B buyers), but they run it differently. First Page Sage is a managed SEO and GEO agency built on a traditional retainer model for enterprise B2B and professional services. Geology is an AI-driven SEO and GEO agency: AI agents run strategy and execution, the team ships the work (technical SEO, content, schema, internal linking, off-site citations), and visibility is tracked weekly across ChatGPT, Perplexity, Gemini, Copilot, and Google AI Overviews. Both do the work for you. The difference is speed, cadence, and cost.

What First Page Sage does
First Page Sage is a US agency that has rebranded heavily around GEO and AI search, positioning itself 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, 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 runs the same done-for-you program with AI agents doing the heavy lifting, which changes the cadence. Visibility is measured weekly across the five major AI surfaces and Google. Page audits flag the pages an AI is misreading, prompt tracking captures the queries your buyers actually run, and the team ships the fixes: content, technical SEO, schema, FAQ structure, internal linking, and off-site citations. Where a traditional retainer reports monthly and ships quarterly, Geology re-measures and re-ships in days. The work is more thorough too, because every priority page is audited every cycle instead of sampled. One insurance distribution startup went from zero AI visibility to 20 organic leads a week from AI, and 3x traditional organic leads, in three months.
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 starts at $3,000 a month. Because AI agents carry much of the execution load, the same scope of SEO and GEO work lands at a fraction of a traditional retainer.
When First Page Sage fits
If your organization prefers a traditional human-led consulting model, wants a long-term retainer structure of a year or more, or values a firm whose published CTR and conversion research your leadership already knows, First Page Sage fits that preference. Those are buying-style factors. The SEO and GEO work itself, from strategy to content to technical fixes, is what Geology runs every week.
When Geology wins
If you want SEO and GEO results without a year-long commitment or a mid-five-figure monthly bill, Geology fits. You get weekly cross-platform measurement and an agency that ships content, technical SEO, schema, and citation work against it. The cost and speed advantages over a traditional retainer compound across a year.
