Search is changing from ten blue links to direct answers. GEO helps your brand earn inclusion inside those answers across ChatGPT Search, Gemini AI Overviews, and Perplexity.

The playbook that grew on-page rankings for fifteen years is still useful, but it is no longer enough on its own. People are asking AI systems for solutions and those systems often respond with synthesized answers that include only a handful of brands. Google reports that AI Overviews now reach more than 1.5 billion users each month [The Verge, Q1 2025].

20-60% Projected decline in organic search traffic for some queries due to AI summaries [eMarketer].

Independent analyses find that links under AI summaries can receive fewer clicks than traditional listings for the same query. [eMarketer trend brief, 2025].

Takeaway: Your brand must compete for inclusion inside answers, not only for positions on results pages.

What GEO is and how it differs from SEO

SEO optimizes documents so a search engine can rank them on a page. GEO optimizes your entire brand footprint so answer engines can confidently cite or include you inside a synthesized response. [OpenAI GPT-4 Technical Report].

SEO Focus

  • • Optimize a page for a keyword.
  • • Win rank and click on SERP.
  • • Signals: backlinks, crawlability.
  • • Metric: Organic Sessions.

GEO Focus

  • • Optimize brand facts/coverage.
  • • Win inclusion inside AI answers.
  • • Signals: clarity, corroboration.
  • • Metric: Mention Rate.

Why this shift is happening now

Usage is the first driver. Consumer and professional adoption of AI assistance is now habitual. [AP-NORC, Aug 2025]. Product evolution is the second driver. Perplexity reports tens of millions of active users. [Business of Apps, 2025].

How AI decides what to include

Answer engines retrieve passages, score them, and synthesize a response. They prefer sources that are authoritative and easy to quote.

Strategy

Instead of marketing language, publish short, explicit statements about your product, target user, and differentiators.

In GEO you track how often you are named or linked inside answers for high intent prompts.
