Google have announced that they will be penalizing the search rankings of sites that display full-screen popup ads.
Sites that use popup ads, interstitial pages, or display full screen “subscribe” offers will be penalized, while sites using popups for logins and adult content warnings will be unaffected by the change.
The specific no-nos included in Google’s announcement include:
- Showing a popup that covers the main content, either immediately after the user navigates to a page from the search results, or while they are looking through the page.
- Displaying a standalone interstitial that the user has to dismiss before accessing the main content.
- Using a layout where the above-the-fold portion of the page appears similar to a standalone interstitial, but the original content has been inlined underneath the fold.
Make sure your website complies with these new guidelines, or you could risk losing a substantial amount of traffic. Especially since mobile web browsers now make up over 60% of browsing traffic.
