Use at your own risk · Listings may be submitted by users, agents or our editors. Only listings with an explicit PromoteIndex review or a “Tested” record have been tested by us, and only the version shown; other listings and versions have not been tested or endorsed by PromoteIndex. Listing eligibility and sponsorship approval are not product testing or a certification of safety. Promoted/Sponsored placements are paid ads. Do your own diligence and scan any downloads before running them. Terms

Detailed listing counters began with the October 17, 2026 update; earlier views and placement attribution are unavailable. Identified search crawlers and other bots are excluded from these detailed counters.
Badge impressions count the badge image being requested from a page on another website (a link-back); cached requests are not counted, so this is a lower bound.
