This score tracks the signals that make a listing useful for discovery and trust. Payment is not part of the score, and the result does not guarantee ranking.
Authority loop
The check looks for a public link between the configured product site and this listing. It does not verify ownership, endorsement, or search ranking. Payment does not change search-link treatment.

Excellent security posture
Your app implements strong security headers. You're in the top tier on the Security Leaderboard. Keep it up - your users are safer for it.
AI makes it easy to build apps fast - but speed without security puts users at risk. We scan every listed app's HTTP headers to surface who's shipping responsibly. Security headers like HSTS, CSP, and X-Frame-Options are the baseline defenses every web app should have. A good score tells users: "this builder cares about my safety, not just shipping quickly."
