Google will start punishing popups soon, making the internet a happier place for mobile users. 🎉 If you insist on using those annoying popups (begging people to subscribe to your newsletter or download your app), Google will drop you like a rock, so fewer people will find you and fewer people will be annoyed. THANK YOU, GOOGLE!! 👍
You have until Jan. 10 to remove those popups, or find your site ranking lowered in mobile search results.
