Indexability

Indexability is a page’s eligibility to be stored in a search engine’s index after it has been crawled. A page may be crawlable but excluded because of a noindex directive, canonical choice, duplicate content, low-value signals or other indexing decisions.

In plain terms

A bot can read the page, but indexability determines whether the engine can keep it for retrieval.

Why it matters

AI systems that rely on search indexes cannot retrieve a page that was never indexed or was consolidated elsewhere.

How to apply it

  • Check index directives and canonical tags.
  • Give important topics distinct, useful pages.
  • Inspect indexing reports rather than assuming a successful crawl is enough.

Example

A crawler fetches a comparison page, but its noindex directive prevents the page from entering the searchable index.

Ranking is no longer enough

You need to be cited, mentioned, and recommended.

Being cited, mentioned, and recommended are three different outcomes, and most brands only ever achieve the first one. Ranking is no longer enough because AI engines answer buyers directly and name only a short list of vendors as the recommendation — everyone else is cited in passing, if at all.
