Barcelona, Spain – 6th October 2020 – Tappx, a leading AdTech company delivering digital advertising solutions for mobile, OTT and desktop, was ranked as the second most listed Direct Ad Partner for Google Play apps which have adopted app-ads.txt to help fight app inventory fraud.

It revealed that Tappx was listed in 23.19% of all Google Play apps featuring app-ads.txt. Only Google ranked higher than Tappx, with it being listed in 96.63% of all Google Play apps.

Fernando Saiz Camarero, CMO at Tappx, commented:
“The fight against in-app ad fraud can only be won through a concerted collaborative effort with all actors present within the mobile advertising ecosystem. At Tappx, we have leveraged the breadth of our developer and publisher network, and promoted the value of adopting the IAB app-ads.txt initiative. We’re pleased to report that to date, Tappx has successfully encouraged app-ads.txt adoption in over 30, 000 Google Play apps.”
He added:
“We reached this milestone for ‘second most listed direct ad partner in Google Play’ by implementing a robust three-point ad fraud prevention strategy: Firstly, we focus on leading transparency rankings, with a rigorous framework present to ensure quality ad inventory availability. Secondly, we educate and share best practices and collaborate with bodies like the IAB, MMA Spain and FaqFraud, and thirdly, we champion industry initiatives such as the rapid adoption of app-ads.txt.”

This includes Tappx, which offers one of the best AdTech solutions on the market.”
