Good on Google for finally taking a stand against pop-up ads on sites. There is nothing more annoying than clicking through a link only to be hit with a giant pop-up that I can’t figure out how to close. And the close button is always in a different place! I can’t stand the ones that try to trick you into clicking through the ad by making you think you’re actually closing the pop-up.
If you’re using one or many of these pop-ups or interstitials on your site, I’d get rid of them immediately. Not only are you creating a terrible experience for your users, but you’re about to get seriously dinged by Google.
