GEO / AEO philosophy

First Page Sage treats GEO as a lead generation discipline and doesn't romance the technical details. However, they developed the GEO framework about a third of GEO agencies use today. Their mantra is authority building + commercially-targeted content = leads & happy clients.

Offering

  • Dedicated GEO/AEO programs built around inbound lead generation, authority building, and content.
  • Category-authority pages and executive-level writing intended to be retrieved and recommended in AI answers.
  • Commercial GEO practice dated to May 9, 2023 on the firm’s materials, on top of an SEO/content agency founded in 2009.

Innovation

First Page Sage’s key innovation is the creation of the GEO industry itself, in many ways. The firm published the first public GEO framework, which most agencies still use today. Separately, it created the first Agentic Search Optimization framework (also called Agentic SEO), a forward-looking method for getting brands recommended inside AI agents. Their focus on R&D shows up in the client experience as well: the firm frequently publishes articles about new GEO strategies and tactics.

It reads like something our own experts would have written, which almost never happens with an outside agency.” ◆ “They are not cheap, but the results have more than justified the investment. Our demo requests from organic and AI sources are up sharply year over year.”
