We track the games’ performance and gameplay based on Your domains, not the games ID. The ads.txt and DFP Form are the tools we use to know how many Gameplay and Ad Impression you are showing on your domains, that is why we strictly ask you to complete all the set up.
The data is reported on Tunnl, you can log in her with your credentials to keep track of your own performance and see all the metrics. Feel free to analyze and adjust your business decision.
