AI search optimization
More of your buyers now ask ChatGPT, Gemini or Perplexity which tool to use before they open Google. AI search optimization is the work of being the product those assistants name, and knowing when you are not. It is the same underlying job as SEO, with one measurement added: did you land in the answer.
You will see this called several things. GEO, generative engine optimization. AEO, answer engine optimization. LLM SEO. They are all the same job under different acronyms, and a tool that does one does all of them. The name matters less than the two questions underneath it: are you named when a buyer asks, and which pages decided the answer.
How it actually works
When an assistant answers with search on, it retrieves a small set of live pages for the exact question, reads them, and names what those pages support. So AI search optimization is two problems in sequence: being in the set it retrieves, then being the clearest thing to quote once you are there. Both come down to being the best, most quotable page on one specific question, on a site the assistants can crawl. The step-by-step lives in how to get cited by ChatGPT and how to rank in Perplexity.
What we measured, 31 July 2026
- Of 259 domains AI cited in the AI visibility category on 31 July 2026, 235 allowed every AI crawler.
- 18 of 244 of those sites block GPTBot but allow OAI-SearchBot, leaving ChatGPT search while opting out of training.
- Only 5 of 259 cited domains block an AI search crawler by name, and all four are large publishers.
Sample: every domain an assistant actually cited across our own checks, not a top-100 list. Blocked means a whole-site disallow for the matching group, so partial rules are not counted and these figures understate blocking. 0 domain did not answer and is excluded rather than counted as open. How we measure
Why you cannot optimize for just one assistant
The three assistants do not agree, and it is not a rounding error. When we put 40 buying questions to all three, of the 437 products they named across the answers, only 30% were named by all three, while 47% were named by exactly one. A single assistant would have shown you 58% to 65% of the products the full panel named, depending on which one you checked. Optimize and measure against all three, or you are tuning for a third of the picture and calling it done.
The pieces, by name
AI search optimization is a small field with a lot of vocabulary. Here is the map, each linking to the measured version.
Start with a measurement, not a guess
The whole field runs on confident numbers with nothing behind them. Do the opposite: run a free check to see whether the assistants name you today and which pages they cite, then fix what the source list shows. In one week our own beacon counted 6 real people sent by an AI answer, each to a page that earned the citation.

Common questions
What is AI search optimization?
AI search optimization is the work of getting your product named and cited when someone asks an AI assistant like ChatGPT, Gemini or Perplexity for the best option in their category. It is the same job SEO does, measured on a new surface.
Is AI search optimization the same as GEO, AEO or LLM SEO?
Yes. GEO (generative engine optimization), AEO (answer engine optimization) and LLM SEO are all names for AI search optimization. The tools and the method are the same; the acronym just depends on who is writing.
Do I need new content for AI search, or does my SEO work?
Mostly your SEO works, because an assistant answers by reading pages that already rank. What you add is measurement, whether you actually landed in the answer, and content shaped to be quotable in one sentence.
How do I start with AI search optimization?
Run a free check to see whether the assistants name you today and which pages they cite, then fix the gaps the source list shows. Watching it over time starts at $9.99 a month for one product.
