What each of the eight checks actually tests

thresholds included

Every check is a rule you could apply by hand, so here are the rules. Two of them have a citation-rate comparison behind them — structured data at 36% vs 10%, crawler access at 32% vs 7%. The right column is the rank correlation with being cited across 48 sources; at that sample size anything under 0.285 is not distinguishable from noise, which is why six of these eight are hygiene rather than findings. The tick marks the two that have a rate comparison.

✓Crawler access — any of the six retrieval agents blocked at / in robots.txt is a red.ρ 0.162

–llms.txt is real — a 200 that returns <!DOCTYPE html is a red, and so is a file that does not start with #. No > summary line is an amber.ρ 0.168

✓Structured data — any application/ld+json on the page. Zero is a red.ρ 0.391

–Word count — under 300 is an amber, 300 to 599 a different amber, 600 and up a green. Chinese, Japanese and Korean text is counted per character, not per space.ρ 0.149

–Question-shaped block — a Question or FAQPage type in the JSON-LD, or the words FAQ or frequently asked in the text.ρ 0.095

–Summary block — a blockquote on the page. Without one the answer stays buried in the first paragraph.ρ 0.070

–Meta description — missing is a red, longer than 160 characters an amber.ρ 0.071

–Heading structure — exactly one h1 and at least three h2 to h4. Zero h1 is an amber; several h1 is an amber too.ρ −0.056

Questions about this check

eight checks, no signup

What are the eight checks?

Crawler access in robots.txt, whether llms.txt is a real file or a fake 200, structured data, word count, a question-shaped block, a summary block, the meta description, and heading structure. We fetch the page, /robots.txt and /llms.txt ourselves, so the only thing you type is the URL.

What happens to the URL I enter?

Our worker fetches that page plus /robots.txt and /llms.txt from the same host, runs the eight checks and returns the result. The page content is not stored and no account is created. The result is cached at the edge for five minutes, so checking the same URL again does not hit your server.

Can I check a page that is not mine?

Yes. The check only reads what any crawler can read on a public page, so any reachable URL works. Getting the page listed in our directory is a separate submission.

Does a green report mean I will be cited?

No. Only structured data and crawler access are checks we have measured against citation rates. The other six are hygiene: they make the page easier to lift, and we have not measured whether they move citations. We would rather say that than sell you a score.

What if the fetch fails?

Some sites block automated requests, sit behind a login, or render their content with JavaScript only. When that happens we report the failure instead of guessing, and you can paste the page source into the advanced box and run the same eight checks in your browser.

What if I do not have a robots.txt?

Then the crawler row says open by default rather than guessing. A missing robots.txt means every crawler is allowed, which is a different finding from being blocked.
