title and meta description

The cheapest signal any extractor has, and the one most often left to a CMS default. A page titled "Home" tells a model nothing at all.

How to pass it

Give every page a <title> and a <meta name="description"> — they are the cheapest signal an extractor has.

Paste-ready

Replace {{ORIGIN}} with your own origin — or call the paid endpoint, which substitutes it for you and tells you which checks you actually failed.

<!-- in <head> -->
<title>Your Product — what it does in five words</title>
<meta name="description" content="One sentence, under 160 characters, that answers what this is and who it is for.">

Check your own site

Free, no signup, same endpoint that produced every grade on the leaderboard:

curl "https://index.percall.dev/api/score?url=https://your-site.example"

It returns the letter grade and every check by name with pass/fail. The $0.05 call at POST /api/audit adds why each one failed and a snippet with your origin already in it.
