What is GEO (generative engine optimization)?
GEO, generative engine optimization, is the work of making AI assistants such as ChatGPT, Google's AI Overviews, Gemini, Claude and Perplexity cite and recommend your business when people ask about your field. It is done with pages that answer real customer questions directly, state checkable facts with sources, and stay open to the crawlers those assistants use.
Facts
- The term GEO comes from a 2023 research paper (KDD 2024), which found optimisation methods raised a source's visibility in generative engine answers by up to 40%. (Aggarwal et al., GEO: Generative Engine Optimization (KDD 2024))
- The same paper introduced GEO-bench, a benchmark of user queries across several domains, and found that the best methods differ by domain. (Aggarwal et al., GEO: Generative Engine Optimization (KDD 2024))
- Google's AI Overviews had over 2 billion monthly users in more than 200 countries and territories by July 2025. (Alphabet Q2 2025 earnings call)
- OpenAI says sites that opt out of its OAI-SearchBot crawler will not be shown in ChatGPT search answers. (OpenAI: Overview of OpenAI crawlers)
- Google states there are no additional technical requirements to appear in AI Overviews or AI Mode beyond being indexed and eligible for a snippet. (Google Search Central: AI features and your website)
Why does GEO matter for a business?
GEO matters because more people now get a single written answer from an AI assistant instead of a list of links, and the businesses named in that answer get the visit. If an assistant cannot find or trust your pages, it recommends someone else.
What does GEO work consist of?
GEO work is a short, repeatable set of tasks on your own website:
- Pages that answer one real customer question each, with the answer in the first sentences
- Facts with a number, a date and a source an assistant can check
- The same price, terms and offers stated identically on every page
- robots.txt and the firewall open to AI search crawlers, plus a sitemap
- Measurement of AI visitors and crawler reads, so the next batch follows the data
Which AI assistants does GEO target?
GEO targets every assistant that searches the web before answering: ChatGPT search, Google's AI Overviews and AI Mode, Gemini, Claude and Perplexity. Each has its own crawler and rules, but all of them favour pages that are readable, specific and consistent.
How can a company do GEO without hiring an agency?
A company whose website lives in a code repository can have its own coding agent do the work. easyIndex connects to that agent over MCP, gives it one GEO step at a time, audits every page before it goes live, checks it on the live site and measures what each page brings.
Common mistakes
- Treating GEO as a one-off rewrite: assistants re-read pages, and the next batch should follow what the data shows.
- Writing vague marketing copy with no numbers, dates or sources, which gives an assistant nothing it can quote.
- Blocking AI search crawlers in robots.txt or at the CDN firewall without noticing it.
- Publishing a hidden Markdown or JSON copy of the site for AI instead of making the real pages readable.
How easyIndex solves it
easyIndex turns GEO into steps your coding agent follows over MCP: it builds the pages in your repository, easyIndex audits each one, checks it live and measures AI visitors and crawler reads, for US$ 30 per website a month after a 7-day free trial.
Frequently asked questions
Is GEO the same as SEO?
No. They overlap, since AI search builds on indexed pages, but GEO aims at being quoted in an AI answer rather than ranked in a list of links. The guide on GEO vs SEO compares them.
Can anyone guarantee that ChatGPT will cite my business?
No. Nobody controls what an AI assistant cites. GEO raises the chance by making your pages easy to find, read and trust, and measurement shows what actually happens.
How long does GEO take to show results?
Crawler reads can show up soon after pages go live; citations and visits depend on your market and on what AI already knows about you.
Do I need special code or schema for GEO?
Google says no extra technical requirement applies to its AI features. Clean HTML, a sitemap, open crawlers and clear answers matter more than any special markup.
