Google to Demote Websites That Display Modal App Download Prompts ⇥ googlewebmastercentral.blogspot.ca

Google engineer Daniel Bathgate:

After November 1, mobile web pages that show an app install interstitial that hides a significant amount of content on the transition from the search result page will no longer be considered mobile-friendly. This does not affect other types of interstitials. As an alternative to app install interstitials, browsers provide ways to promote an app that are more user-friendly.

Thank you.
