In short
AI search means the search engine answers the question itself and cites a handful of sources, instead of handing you ten links. This section explains what actually changed, what GEO and the other new labels mean, how assistants pick their sources, and what all of it has done to website traffic.
Key points
- The result page is becoming an answer. Ranking still matters, but the answer sits above it.
- GEO, AEO and LLMO are labels for the same work. Do not buy them as three services.
- Assistants pick sources in stages, and each stage can be influenced.
- Traffic per impression is falling while AI referrals grow from a small base. Both are measurable.
What changed
For twenty years a search produced a list, and the game was to be high on it. Now the search engine increasingly writes the answer itself, cites three or four sources inside it, and the list sits underneath, read by fewer people every quarter.
That single change breaks an old equality. Ranking used to mean being found. Now a page can hold position one and still be invisible, because the answer above it resolved the question and nobody scrolled. The work splits in two: earn the click where clicks still happen, and earn the citation where they do not.
None of this made search smaller. People ask more questions than ever, and they ask them in more places: Google, ChatGPT, Perplexity, Copilot. What shrank is the guaranteed click per query. What opened is a new way to be present, as the source an answer names.
What did not change
The unfashionable part first: most of what earns AI citations is what earned rankings all along. A crawlable site. Content that matches what people actually ask. Real expertise, stated plainly. Being a recognisable entity rather than an anonymous domain.
Assistants ground their answers in search indexes, Google's, Bing's or their own. A page that cannot rank anywhere is usually a page that cannot be retrieved, and a page that cannot be retrieved cannot be cited. SEO is not the thing AI search replaced. It is the thing AI search runs on.
The order to read this in
- What is AI SEO? frames the whole subject: what carries over from SEO and what genuinely changes.
- GEO vs AEO vs LLMO clears the label confusion in five minutes.
- What is Google AI Mode? and How AI Overviews changed traffic cover what happened to Google, with the published numbers.
- How assistants choose citations is the mechanism. If you read one page slowly, read that one.
- Which platforms send traffic ends the section where your analytics begin.
After this section, Getting found by AI covers the technical layer: crawler access, JavaScript and the files at your site root.
FAQ
What is AI search? Search where the engine generates an answer to your question and cites a small number of sources inside it, rather than only returning a ranked list of links. Google AI Overviews, Google AI Mode, ChatGPT search, Perplexity and Microsoft Copilot all work this way.
How is AI search different from normal search? Normal search ranks pages and you choose one. AI search reads a handful of retrieved pages, writes one answer from them, and names its sources. The competition moves from winning a position on a list to being one of the sources the answer is built from.
Is SEO still worth doing? Yes, and it is the prerequisite. Assistants retrieve their sources from search indexes, so a page that cannot be crawled and cannot rank is invisible to them too. The sensible framing is SEO as the foundation with citation work layered on top, not one replacing the other.
Do AI answers actually reduce website traffic? For informational queries, yes, and the published studies measuring it agree on the direction while Google disputes the size. Clicks per impression fall when an AI answer is present. The detail, and how to measure it on your own site, is on the AI Overviews page in this section.
What should I read first in this section? Start with What is AI SEO. If you only have half an hour, read that and How AI assistants decide what to cite. Everything else in the section supports those two.
