Generative Engine Optimization (GEO) is the practice of structuring your content and site so AI engines — ChatGPT, Perplexity, Gemini, Claude, and Google's AI answers — cite and recommend your brand in their responses. Where SEO targets a ranked list of blue links, GEO targets the single synthesised answer an AI gives.

It matters because behaviour has shifted. AI assistants now field a huge share of the questions people used to type into a search box, and they usually return one answer with a few citations. If you're not in those citations, you're invisible — no matter how you rank on page one.

How GEO differs from SEO

  • SEO optimises for ranking in a list; GEO optimises for being quoted in an answer
  • SEO rewards keywords and links; GEO rewards clear claims, evidence, and structure
  • SEO is one engine (mostly Google); GEO spans several AI platforms with different habits

The core GEO playbook

  • Answer first — put the direct answer in the opening lines, then explain
  • Structure for extraction — clear headings, short paragraphs, lists, and a TL;DR
  • Add a real FAQ — AI loves clean question-and-answer pairs
  • Show expertise — named author, visible dates, specific facts and figures
  • Add schema — FAQPage, Article, and Organization markup help AI parse you
  • Stay fresh — recently updated content is cited far more often
  • Earn mentions — citations from trusted third parties build authority

Platform quirks worth knowing

  • ChatGPT web search leans on Bing's index — so submit your sitemap to Bing
  • Perplexity favours fresh content and heavily cites community discussion
  • Google's AI answers favour pages that already rank well and have strong E-E-A-T

How to measure it

Pick 20–50 questions a customer might ask an AI in your category. Ask them across ChatGPT, Perplexity, and Gemini, and count how often you're mentioned versus competitors. That share of citations is your GEO scoreboard — track it monthly.

GEO isn't a replacement for SEO; it's the next layer on top of it. The same content that's clear, credible, and well-structured tends to win in both.
