If this is happening, then check a few things first:
- Is the ads.txt already added?
- Are all your domains added in the Ad Manager via DFP Form?
- Is there enough traffic on your domain that are playing our games? Note: we only take into account the traffic that actually plays games, not the traffic only landing to a game page.
- Are you targeting the right demographics? Are the games suitable for them? For instance, girl-game-page is not a right place for a shooting-game.
If all this checks out and you are still not seeing any traffic, please contact our account team for advice.
