To make sure that developers who are legitimately using this flow to offer users a subscription don’t get caught up in this new system, Google also published a set of best practices for mobile billing today. Generally, developers are expected to make their billing information visible and obvious to users, display the actual cost and have a simple and straightforward fee structure.

If that information is not available, Google will throw up a prominent full-page warning, but users can always opt to proceed. Before throwing up the warning page, Google will notify webmasters in the Search Console when it detects a potential scam (there’s always a chance for false positives, after all).

This new feature will be available on both mobile and desktop, as well as in Android’s WebView.
