How does Apptopia determine who the Top Advertisers are?

Top Advertisers is a composite rank based on the number of creatives seen from that advertiser, the freshness of those creatives, and the performance of the apps being advertised (DLs, DAU, MAU and more)

Use Top Advertisers for discovering who is dedicating the greatest resources towards advertising and having the most success. See which creatives are driving the best results, learn best practices of in-app advertising, and benchmark your campaigns against top-tier peers and competitors
