I bet this probably annoys you.
You click on a link in Google to read something awesome, and before you can read the content you get this giant …thing… in the way holding that poor, defenseless content hostage unless you agree to sign up for something or watch a countdown with an ad.
They’re called “intrusive interstitials”, and it turns out Google doesn’t like them either. So it’s going to penalize sites that use them.
If your site uses these or something like this, you’ll want to make sure you’re clear of Google’s rules, or you could see your rankings take a hit.
