Top 7 App Store Optimization Tools 2021 [For Apple Store & Google Play]

Curious if you should go ahead and leverage App Store Optimization tools in your mobile app marketing campaigns?

Ok, I may not know the type of campaigns you’re using to promote your app, but I can tell you one thing – App Store Optimization is the king of mobile app marketing.

You see, while there are numerous ways in which Android and iOS users continue to find new apps, the Google Play Store and Apple App Store have always been the top app discovery channels.

According to a U.S study by Google in conjunction with Ipsos, nearly half of all smartphone users discover new apps while browsing Google Play Store and Apple App Store. An earlier Forrester report, on the other hand, places discovery by App store search at 63% for iOS apps, and 58% for Android apps.

Now that’s precisely where App Store Optimization comes in. And to help you with the whole thing, this article provides insights into:

    • What App Store Optimization is all about.
    • The relevance of App Store Optimization tools, and why you need them in your mobile app marketing campaigns.
    • The five types of App Store Optimization software, and the leading tools across each category.
    • The 7 best overall App Store optimization tools in the market today – along with their key features, pricing, as well as the pros and cons.

As such, you can think of this as the ultimate guide to App Store Optimization tools for both Apple App Store and Google Play Store.

Now to start us off, why the heck do you even need ASO tools in the first place?

Why Use App Store Optimization Software?

By now, you can bet that most app developers and app publishers are aware that App Store search is the principal driver of app discoverability. So, to boost their app downloads and app installs, they tend to tweak their app keywords, app titles, and app descriptions – for both Google Play Store and Apple App Store apps.

These App Store Optimization techniques are meant to improve their app ranking in the keyword search results. And yes – after working with over 3,250 apps so far, I can confirm that the methods are indeed effective when it comes to enhancing your app’s visibility.

But, here’s the thing according to Statista – with over 3.1 million Android apps in the Google Play Store and nearly 2.1 million iOS apps in the Apple App Store, it’s obvious that ASO competition is now tougher than ever.

The limited slots at the top of the App Store search results are now reserved for the few apps that go beyond just basic keyword optimization. I’m talking about the smart app publishers who choose to cleverly take advantage of advanced App Store Optimization techniques – which are often facilitated by ASO tools.

You see, with App Store Optimization tools, you get to:

    • Gather app market intelligence and App Store Optimization intelligence for informed decision-making.
    • Run tests on various App Store pages to identify the one that connects best with your target app users.
    • Gain insights into what users like and hate about your mobile app.
    • Conduct accurate keyword research.
    • View keyword suggestions.
    • Track your app ranking across Google Play Store and Apple App Store.
    • Keep tabs on your competitors’ performance.
    • Enhance your Apple search ads.

Don’t get me wrong, though. You won’t find all these capabilities in one App Store Optimization software. Instead, you’ll notice that each ASO tool specializes in just a handful of functionalities.

They come either as app keyword optimization tools, review and sentiment analysis tools, A/B testing tools, search ads optimization tools, or App store intelligence tools.
