In an effort to improve the mobile browsing experience, Google has announced it will begin measuring whether page content is speedy and easily accessible. Starting in January 2017, if Google detects that the content on a mobile device has been covered by a pop-up or interstitial ad, they may lower the SEO rankings for that page.

To protect your hard-won SEO, we suggest that you swap your mobile pop-ups and interstitials with pencil and leaderboard ads. These ads are still high impact, but steer clear of Google’s new SEO policy. (Learn more about creating ads in BLOX CMS.)
