What ChatGPT keeps of your page
ChatGPT search mostly works from about the first 200 characters of a page's main text. Enter a page to see its opening, what spends it before the H1, and a better one built from your own H1.

What it checks
The opening
The first ~200 characters of the main content (<main>, else <article>) of the server HTML, as AI crawlers read it without JavaScript.
What comes before the H1
Dates, bylines, breadcrumbs, kickers and banner text that take the snippet's space, judged with the same rule as Optimz's site audit.
A better opening
Your H1 and the first sentence under it, cut to the snippet length: what the stored snippet could say instead.
Questions
What part of my page does ChatGPT search use?
Tests of ChatGPT's search index found it mostly works from a short snippet stored at crawl time: about the first 200 characters of the page's main text, not the meta description. Pages whose opening states what they answer are easier for it to pick.
What spends those 200 characters?
Kickers (“NEWS”), dates and bylines, breadcrumbs, image captions and banner text placed before the H1 inside the main content. Navigation, buttons and hidden elements don't count.
How should a page open?
With its H1, followed by one sentence that answers the question the page is about. Move dates, breadcrumbs and promotional text below the first paragraph or outside the <main> element.
Does this tool use AI to write the suggestion?
No. The suggested opening is your own H1 followed by the first sentence of the paragraph under it, cut to the snippet length, so you can see what a clean opening would read like.
