Google’s John Mueller and Gary Illyes have confirmed that intrusive mobile interstitials penalty started rolling out on 10th January 2017. Almost six months ago Google had said it was coming and no it is finally there.
This penalty impacts intrusive interstitials that occur when someone Google’s mobile search to the web page. It has no direct impact on desktop search. Below are the few examples of intrusive mobile interstitials:
- 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.
By contrast, here are some examples of techniques that, used responsibly, would not be affected by the new signal:
- Interstitials that appear to be in response to a legal obligation, such as for cookie usage or for age verification.
- Login dialogs on sites where content is not publicly indexable. For example, this would include private content such as email or unindexable content that is behind a paywall.
- Banners that use a reasonable amount of screen space and are easily dismissible. For example, the app install banners provided by Safari and Chrome are examples of banners that use a reasonable amount of screen space.
