Crawled, indexed, cited, where AI traffic begins
Three gates, and passing the first two says nothing about the third. What decides whether an answer engine names you as the source.
Three words get used as though they mean the same thing. They describe three different states, and the distance between the second and the third is where most AI-referred traffic is won or lost.
Crawled
A bot fetched your page. That is all it means.
Crawled is necessary and close to worthless on its own. It proves your server responded and the URL exists. It says nothing about whether the content was readable, whether it was stored, or whether anyone will ever see it. A page can be crawled every day for a year and appear in nothing.
This is the step people over-index on, because it is the easiest to verify: your logs show the bot arriving, and that feels like progress.
Indexed
The engine stored your page and can retrieve it.
This is a genuine milestone and a real bottleneck, particularly for new sites and for anything published faster than a crawler naturally revisits. A whole category of tools exists to accelerate it, pinging indexing APIs across Google, Bing and the LLM crawlers, and they work: indexing latency is a real problem with a real solution.
They also stop here. Which is reasonable, because it is a different problem from the next one.
Cited
An answer engine named you as its source.
This is the one that produces traffic now, and it does not follow from indexing. Being in the index makes you eligible to be cited. Whether you actually are depends on things indexing tools do not measure and cannot influence:
- Whether the answer is extractable. Engines lift passages, not pages. A claim buried in the eleventh paragraph of an essay is harder to quote than the same claim stated directly under a heading that matches the question.
- Whether you are attributable. Some engines cite by design: Perplexity is built around it. Others cite selectively, and prefer sources they can characterise: a named author, a date, a site that looks like it knows the subject.
- Whether a competitor is easier to quote. Citation is zero-sum per answer. You are not competing against a threshold; you are competing against whichever three sources the model found easiest to use.
Why the gap persists
Because almost nothing measures it. Rank tracking tells you your position on a results page that a growing share of your audience never sees. Index checkers tell you the page is stored. Neither tells you whether ChatGPT, Claude, Perplexity or AI Overviews named you when someone asked the question your page answers.
Measuring it means asking the engines, repeatedly, for the queries you compete on, and recording who got cited. That is a different instrument from a rank tracker, and it is the one that tells you whether the work is landing.
What to do about it
Start by finding out where you actually stand: not on rank, on citation share for the queries that matter to you. Then work the extractability problem: headings that match real questions, answers stated plainly near the top, structure a machine can lift without inferring.
None of that is a trick. It is the same advice as “write clearly”, enforced by something that reads your site the way the engines do.
