Google Play clearly states which applications have in-app purchases, and starting in 2016, it'll also be more transparent when it comes to ads. According to Droid Life, Mountain View has notified developers (see the full email below the fold) that they're required to sign into their consoles and declare whether their applications have advertisements. And, if they lie about it, they could face suspension. Google originally launched the "ad-supported" tag in April in its kid-friendly Play Store as part of the Designed for Families program. Now, developers only have until January 11, 2016 to tag their apps, since the label itself is slated to begin showing up in the regular Play Store "early next year."
