Methodology & limitations
Counts are valid seller entries fetched from public app-ads.txt files when this snapshot was loaded. Repeated entries are counted; domains are not merged by corporate group. This is a limited sample, not unique publishers, reach, revenue, market share or an endorsement. Snapshots are cached briefly; source-check dates are shown. Categories come from Directory profiles, not certification.
Equal values share a rank. Names break ties for display; each list is capped at 50 domains. Zero values are excluded, not treated as poor performance.
