Why Google Is Waging War on App Interstitials

Google waging war on app intersitials

It has been a topic of discussion in the web design world for a while now, but the news that Google has declared war on app interstitial is no less striking. Beginning November 1, websites that make use of interstitials, which hide a significant amount of content, are set to be penalised, and will no longer be considered mobile-friendly.

As you know, app download interstitials are widely used, completely dominating a screen by overlaying the website content with a single advertisement. The product could be a website’s own app, or a mailing list signup form or a more general type of advert.

But since they are designed to stop site visitors in their tracks, it’s hardly surprising that the overall reaction has been negative. In fact, there is plenty of data to suggest interstitials are more likely to backfire on a promotional campaign. But why is Google taking such a strong stance? And what does this actually mean for web designers and users alike? Here are a few of the main reasons.

Interstitials: Unloved and Unwanted

The issue is not so much the fact an advert for a new app appears, but the level of intrusion it causes. It’s a bit like an over-zealous sales person jumping out in front of you while you enter a store, then repeating the action as your browse. Would you give in and engage, or just leave the store and stay away?

Google themselves came to the conclusion that promotional app interstitials were more trouble than they are worth, at least in terms of user satisfaction. Their own study in July 2014 involved examining user reactions to an interstitial on its own Google+ mobile web, and the vast majority of visitors were clearly not happy.

  • About 70% of visitors abandoned the page completely
  • Only 9% pressed the ‘Get App’ button

When they removed the interstitial, and replaced it with a Smart App Banner, they recorded:

  • A 17% increase in one-day active users
  • Just a 2% decline in app installs

Comparing the results, Google concluded that there was effectively no advantage in using the more intrusive full screen app interstitial over the banner.

So, they decided to “permanently retire the interstitial”.

The motivation behind Google’s test came partly from Jennifer Gove, who highlighted the frustration of mobile users when access to a website is blocked by a full-screen app interstitial – or “Door Slam” as it’s also known.

“The user wants to get some experience of your company or to do some task, and they didn’t appreciate anything that hindered them from doing that… [In this situation] you are losing the opportunity to engage with users,” she pointed out.

What Google’s Move Means

1. Mobile-Friendliness is a Ranking Factor

Every site needs its advertisements, whether for the company’s own apps or for a source of revenue from partners. However, high ranking is also critical. Thus the need to not impede visitors with intrusive promotions has become more significant than ever.

2. More Real Estate

We all know that space on a mobile site is at a premium, so it stands to reason that any unnecessary consumption of that “screen real estate” is going to be counter-productive. With the clearly negative reaction users have to app interstitials, there seems little point in creating them anyway.

3. Better User Experience

In their announcement, Google issued a battle cry: “Let’s remove friction and make mobile web more useful and usable!” Basically, let’s stop irritating users, and give them what they want.

4. Smoother Navigation

Related to the above point, but still worth mentioning. With some interstitials being difficult to dismiss (often purposefully designed as such), navigation is strongly impeded. That issue is gone.

5. New Thinking

Designers can simply opt for less intrusive app promotion methods, with 2 in particular recommended by Google themselves.

  • Banner app advert, either created through HTML or supported by a specific browser; or
  • App indexing in the case of Android apps, with Google showing an “Install” button when indexed content from your app is relevant to a specific query.

Interestingly, The New York Times has come up with another option, one they have named “Called Mobile Moments”. In essence, it matches the preferences of users according to each of 7 specific times (moments) of the day. Introduced in September, this idea corresponds with the results of a year-long study to see what their readers are open to reading at specific times of the day.

It’s an option that places control firmly in the hands of the user. So, new user-controlled promotional forms are in demand.

  • Interesting article, though I am not much of a fan of certain apps. I wouldn’t be surprised if Google wages war on apps such as interstitials that is not beneficial to a website. I mean, it’s going against Google’s practices. If a website is confusing to navigate not just for humans but for bots, they get penalized…so why not on apps?

  • This is really getting more interesting in how Google reacts to mobile users experience. What’s next?
