How to write a description AI can quote

When a model is asked what your product is, it quotes the first sentence that reads like an answer. Without one it either invents a description from your headings or skips you for a competitor whose page states it plainly.

What 13x checks

This is rule aeo.definition-paragraph in the public registry: A citable description near the top. It runs on every audit, against the pages we actually fetched, and its result is derived from the response rather than estimated.

Registry version 2026-07-30. Every rule is published, and the audit is deterministic — the same page produces the same finding every time.

The fix

The same text the audit hands you when this check fails on your own site.

Put one plain sentence near the top that answers "what is this":

html code
<h1>Your headline can stay as it is</h1>
<p>
  example.com is a <!-- category --> that <!-- what it does --> for
  <!-- who it is for -->.
</p>

Concretely:

html code
<p>
  Acme is an invoicing tool for freelance designers. It turns a tracked project
  into a sendable invoice in one step and chases late payment automatically.
</p>

Aim for 15–40 words, in the third person, naming the category explicitly. A slogan — "Invoicing, reimagined" — reads well and tells a model nothing, so it gets skipped in favour of a competitor whose page states it plainly.
