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

Serve over HTTPS; several crawlers will not follow an http:// origin at all.

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.
