Appsflyer Brings Mobile Attribution to the Web

Martech vendor Appsflyer announced a Web Performance Measurement solution that extends parts of its mobile attribution capabilities to web environments. The product aims to provide unified attribution, conversion-signal replay to ad networks, cross-channel creative analysis, and combined cost-and-revenue views so advertisers can evaluate app, mobile web and desktop activity on a common measurement basis within Appsflyer’s infrastructure. Appsflyer frames the move as part of an omnichannel strategy already described by Chief Business Officer Gal Ekstein, while Chief Product Officer Barak Witkowski emphasises that gaps between web and mobile measurement drive suboptimal optimizations. The company warns that success depends on signal quality, data hygiene, fraud detection, privacy rules and matching approaches.
