What AI visibility actually means
Being named in an AI answer is a retrieval problem before it's a content problem. Here's the difference from classic SEO.
AI visibility is whether a model names, links, or summarises your site when someone asks a question in ChatGPT, Perplexity, Claude, or Google AI Overviews.
Classic SEO competes for a position in a list of links. AI visibility competes to be the source inside a single synthesised answer, frequently with no click involved at all. That changes what’s worth optimising.
Three layers, in order
1. Fetch. Can a retrieval agent request your page and get content back? A Disallow you inherited, a WAF in blocking mode, or a 403 on /llms.txt all end the story here. No amount of good writing survives this layer.
2. Extract. If the page is fetched, is the answer findable inside it? Models quote figures, direct statements, and comparison tables far more readily than they quote atmosphere.
3. Earn. A large share of citations point at pages you don’t own, including review sites, listicles, forum threads, and competitor comparisons. On-site work alone rarely wins a contested category query.
Most tools start at layer two and never check layer one. That’s backwards, and it’s why “we improved our content and nothing happened” is such a common complaint.
Why the order matters
If layer one fails, layers two and three are unreachable. If layer three dominates a query, editing your homepage is the wrong move. You need a mention on the page that’s already winning.
Knowing which layer you’re stuck on is most of the work. It also stops you from spending a quarter on the wrong thing.
What that means practically
Check that retrieval agents get a 200. Confirm your key pages are discoverable from a sitemap. Then look at the pages actually being cited for your questions and ask what they do that yours doesn’t.
That’s the loop: find the layer, make one change, re-run the questions next week.
