Top App Store Optimization Agencies (2019)

Updated: December 11, 2019

There are two major ways of how people discover and install mobile apps on their smartphones and tablets. It’s either via advertising of any sort or via search on an app store. App installs that are obtained via app stores built-in search are called organic app installs.

If you, as an app marketer, aren’t taking full advantage of organic app installs, you’re missing a great deal on your best app users. An organic install is more valuable because it’s based on people’s clear intent to find and install a certain app to serve a specific need, which isn’t the case when he is exposed to an ad.  It’s a higher quality customer relationship from the get-go. In short, discoverability matters. And the best way to get noticed in a crowded app store is through app store optimization (ASO) – a process of optimizing mobile apps to rank higher in an app store’s search results. So, how do you apply ASO techniques? Can you do it on your own, using App Store Optimization Tools or you’ll be better off to leave it to the experts?

Consider this number – more than 90% of an average app’s installs are organic. This is where app store optimization services and agencies can help.

ASO specialists say, app store optimization is a continuous process; that you must research, test and iterate to keep up with the competition. And, as app stores continues to grow and hence the completion grows as well, it’s going to get a lot more complex. Back in 2016 some commentators predicted ASO will morph into App Marketing Optimization (AMO), covering all areas of an app marketing funnel. Today, experts say app store optimization must go beyond keywords. It’s about understanding the user intent and measuring their response, to uncover what works and what doesn’t. It implies factoring in all elements of an app marketing copy to attract and retain app users.

As ASO evolves, a number of app store optimization trends have emerged. Since 2013, when Google announced it would start indexing deep app content, mobile apps increasingly replace mobile web in search results. This means, if your app’s content appears in Google search results, and the user has your app installed they’ll have the option to click through and view the content directly in the app. If they don’t have your app installed they’ll be directed to the app store listing for it. Through app indexing, marketers can use deep linking to drive downloads and boost ASO rankings; essentially closing the gap between SEO and ASO.

A/B testing, yet another ASO technique, has also taken off in the mobile app world. App marketers are now conducting real-time examinations of app store icons, descriptions, keywords and screenshots to discover how they affect traffic to their app. A/B testing is a powerful process that helps you find your best converting app store content and optimize your ASO strategy.

The past few years have seen a huge increase in ASO-savvy agencies and service providers able to power ASO and help app developers scale their apps. So if you want to free up your time to concentrate on creating great apps, check out our list of the top app store optimization agencies for 2017.
