GEO (Generative Engine Optimization)

GEO (Generative Engine Optimization) is the set of practices that make web content citable and picked up by AI answer engines like ChatGPT or Perplexity, as well as by AI summaries built into search results. It targets direct citation inside a generated answer, not just a click on a link.

GEO and SEO: two complementary goals

SEO optimizes a site to rank in a list of clickable results. GEO optimizes content to get pulled, as is, into an answer generated by a large language model, with or without a click back to the source. Both rely on the same technical foundation: a fast, accessible, well structured, up to date site. They diverge on the end goal: SEO chases traffic, GEO chases citation and brand visibility inside the answer itself. A page can rank well on Google and still never get cited by an AI answer engine, because its wording does not lend itself to extraction. That extraction is the real target of GEO.

How to scope a GEO project

A GEO project starts with an audit of what AI answer engines already say about your company and your competitors. It continues with structuring existing content: direct answers near the top of the page, self contained definitions, verifiable facts, and structured data (schema.org) that states explicitly who you are and what you sell. A site with vague structure or fuzzy content has little chance of being cited, whatever its SEO ranking. If you are redesigning your corporate or marketing website, this is the moment to build these foundations in rather than bolt them on later, since retrofitting them onto a live site takes more work than building them in from the start.

The concrete levers of GEO

  • Citable content: direct answers, self contained definitions, sourced figures, written to be lifted out of context.
  • Structured data (schema.org): FAQ, HowTo, and Organization markup that states your business explicitly instead of implicitly.
  • An llms.txt file: tells AI crawlers the site structure and which pages to prioritize for summaries.
  • Content freshness: visible update dates, content that gets revised instead of sitting untouched for years, since answer engines tend to favor sources that show recent activity.
Questions
Does GEO replace SEO?

No. AI answer engines still rely heavily on the same signals as classic search engines: authority, structure, freshness. GEO adds a layer of citability on top of solid SEO foundations, it does not replace them.

How do I know if my site shows up in AI answers?

Ask an AI answer engine the same questions your customers typically ask, and check whether your company, offers, or content show up in the answer. It is a quick, free test worth repeating regularly, since answers shift with every model update.

Does GEO mean rebuilding my whole site?

No, not in most cases. The main levers, content structuring, structured data, an llms.txt file, can be added to an existing site without a full redesign. A redesign becomes worthwhile if the site is old, slow, or structured poorly enough to block these additions.
