Usually because they cannot read it, or because there is nothing on the page worth lifting. The free site check reads your pages as an answer engine's crawler does and names which of the two it is — a page built in the browser hands a crawler an empty shell, and a page of two hundred words answers nothing fully enough to quote.

The shape of it, drawn at a size the figures can be read. Placeholders, not a customer's numbers.
Whether the crawlers behind assistant answers are allowed in at all. Whether the pages carry real text in the first response or assemble it afterwards from a script — the single most consequential thing we can tell most sites. According to Google Search Central, Googlebot runs a page's JavaScript before judging it; most of the crawlers behind assistant answers do not, so a site built that way can rank in search and still never be quoted.
One real example from a check: a page shipping 170KB with 26 words of text in the first response. Google sees the 2,441 words that arrive afterwards. An assistant's crawler sees 26.
It is not a theoretical failure. In an August 2025 case study by Glenn Gabe, ChatGPT was asked about a fully client-side page and replied that it "could not read the content of the page because it relied on JavaScript-based rendering".
Then the pages themselves: whether each answers its own question in the opening, carries figures worth quoting, says when it was written, and is broken into sections under 320 words that can be lifted whole. Under about 200 words a page rarely answers anything fully enough to be quoted over a fuller page elsewhere.
It becomes a brief. A finding about code, a bundle, hosting or a template is written up with the measured evidence, the named files, the steps and the test that says whether it worked — the shape you hand to a developer, or paste into whatever built the site.
We will never answer a finding by explaining that we cannot access your code. You already know that. What you do not have is the thing to give the person who can.
Yes, every time you ask, on any package and before you have bought anything. It reads 8 pages in a few seconds, costs you nothing, and is the only step that can say something true about a site nobody has measured yet. Putting a price on it would mean nobody ever found out whether we were worth paying.
