Mobile Interstitials

A mobile interstitial uses a significant portion of the screen on a mobile website to inform and encourage users to open the native app, or install it if they don’t have it. Interstitials are a more aggressive form of promotion your app because to display one you normally have to hide a significant portion of your mobile website. These are most commonly used when companies have determined that while intrusive interstitials make business sense because an app user is more valuable than a mobile web user.

At the start of 2017, Google announced that it would begin enforcing penalties on certain mobile sites that show large interstitials, which prohibit users from easily interacting with the content on mobile websites. If a given mobile site doesn’t comply with Google’s requirements around intrusive interstitials, it will rank lower in Google search results.

There are a couple reasons why Google wants to put a limit on these interstitials. Google has stated that these user experiences “can be problematic on mobile devices where screens are often smaller.” However, Google also wants to more easily contain users in its walled garden, and not allow them be so easily linked out of their search engine or their Chrome browser.

The good news is that you can display calls-to-action (CTAs) for your audience without incurring search ranking penalties from Google. Specifically, you have two real options:

Solution 1: Use Apple and Google Smart Banners to drive app installs.
Google explicitly stated that these banners will not be penalized under their restrictions. The downside with this option is that the banners will stay the same for all users across all pages of your website, and there is no real ability to customize these banners.

Getting clear attribution on these banners is also difficult. Marketing teams who choose to use these banners to drive app installs will not be able to fully understand their campaigns, because they won’t be able to discern which original sources led to which app downloads.

Lastly, users cannot be deferred deep linked through the install process. Thus, users will end up on the app homepage, rather than being routed directly to the specific page or product they were originally viewing. Dropping app installers on the app homepage, unsurprisingly, is reportedly a less satisfying user onboarding experience, and leads to lessened rates of engagement and conversion down the line.

Solution 2: Use homemade smart banners or interstitials to drive app installs.
There remains the possibility to develop your own homemade banners or interstitials in compliance with Google’s regulations. The clear drawback here is that any sort of customization to creative assets can’t be easily executed by members of your Marketing team, and will require extensive work from your Engineering team

Furthermore, this option leaves your Marketing and Engineering teams most vulnerable to any developing regulations from Google’s end. Your prized homemade banner or interstitial could be harshly penalized under Google’s next set of interstitial regulations, and then it could well be back to drawing board for you and your teams. As such, developing your own Google-compliant smart banner or interstitial could mean a substantial initial investment as well as intermittent (not to mention unpredictable) subsequent investments of marketing and engineering time, talent, and resources.
