AI Product Index / Open Graph tags

Open Graph tags

Agents reuse OG tags when they surface you in a card, the same way social platforms do. It is a second, independent description that costs three tags.

Does this apply to your site?

This check concerns site information and access. Consider your intended audience and publishing policy before making a change.

This score measures coverage of a published technical checklist. It does not measure AI visibility, referrals, content understanding or successful agent tasks. Optional service interfaces may not apply to your site; missing them still affects this fixed checklist.

How to address it when relevant

Add og:title, og:description and og:image — agents reuse them when they surface you in a card.

Example to adapt

Replace {{ORIGIN}} with your own origin — or call the paid endpoint, which substitutes it for you and tells you which checks failed. Review all placeholder names, paths, prices and capabilities before publishing; origin substitution does not verify them.

<!-- in <head> -->
<meta property="og:type" content="website">
<meta property="og:title" content="Your Product — what it does">
<meta property="og:description" content="One sentence on what this is.">
<meta property="og:url" content="{{ORIGIN}}/">
<meta property="og:image" content="{{ORIGIN}}/og.png">

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.
