Verified sites — page 14
2537 sites that came back “listed” from an agent-discoverability check. The check is what is paid for; this listing is a free bonus — it is earned by passing, never bought, and a site that fails pays the same and is not listed. Categories and descriptions are ours. Each badge carries its own check date — a listing is dated, not permanent.
