Updated: August 4, 2020

App Store Optimization (ASO) is the process of optimizing a mobile app’s marketing copy (keywords, title, icon, screenshots, description, etc.) to rank it higher on app stores and is often described as app store SEO. If you’re a developer trying to make your app stand out in a crowded app store, the right App Store Optimization tools can play a crucial role in your app marketing and help boost your app’s visibility to increase downloads.

This guide goes over the different aspects of App Store Optimization before listing the best tools out there to get your mobile app to the top of the store, whether its Google Play for Android or Apple’s App Store on iOS.

ASO has many parts to it, from keyword optimization to screenshots and analyzing reviews. The companies listed in this guide offer a range of app store optimization services, from app analytics to reports, intelligence and app review & sentiment analysis.

So what is App Store Optimization (ASO) and what types of ASO companies exist? The sections of this guide break it down as follows:

First up, the starting point of a mobile app ASO that brands and app developers should take care of – App Marketing Copy Optimization.

App Marketing Copy Optimization

App Marketing Copy Optimization deals with app screenshots, the preview video, the app’s icon – basically everything that isn’t text. Many users will download your app or turn away simply by the look of those screenshots or the preview video. Further, if they recognise your brand or app from the logo, they are more likely to download it.

There’s a technical side to asset optimization as well – the screenshot needs to fit within the app store, it needs to be cropped properly and show the right features. Any old picture or screengrab won’t do.

Keyword Optimization

Keyword optimization includes all the text in your app’s page, from the title to the description. Key words being present is of course important, but so is good writing – you have to convince users to download your app with very few words, so each one counts. App store keyword optimization isn’t as easy as dumping all the keywords either; ranking algorithms are getting smarter and users will rate the app negatively when they see that kind of behavior.

Good writing and choosing the right keywords is thus crucial to getting a good rank in the app store. What about including the most important keyword in the title? According to some studies, it can increase app store ranking by as much as 10%, so if you can do it without sounding contrived, then you should.

Something else to keep in mind is that localization is key – a good translation of your description that is sensitive to cultural norms and knows how to speak in the target language is the difference between a successful app and missing out on an entire country’s (or language’s) market.

Types of ASO Tools

App Store Intelligence Tools

Data is what makes mobile app industry tick, having robust, up-to-date analytical information is what allows app marketer to rank apps and connect them with users. There are number of companies that supply app development powerhouses and indie developers studios with such app data, the biggest are App AnnieSensor TowerApptopia and Prioridata. They are capable of making sense of the mass of data that comes out of iTunes and Google Play. From reports on the top new apps and how they got to the top to tracking user reviews by app version (to see how changes affect reviews), the tools offered are extremely useful. Some of the platforms also have a free level to their pricing plan so you can try before you buy.

App Keyword Optimization Tools

These ASO tools function is to monitor and capture specific keywords performance data, provide app developers with keyword analytics and suggest ways to optimize a mobile app marketing copy elements such as title, keywords set, description and provide an API to implement these changes to apps on the App Store or Google Play. Also they provide data on keywords rankings, using in-house built algorithms, including AI-based ones.  Examples of such keyword trackers are companies like App RadarApp Tweak that track a number of keywords for apps, when they’re used in app store pages and how those apps perform. Another feature that such keyword trackers provide app developers is app store localization to improve a mobile app rankings across multiple app stores and hence increase app downloads number in multiple countries.

Review & Sentiment Analysis Tools

App store reviews and ratings are crucial in shaping app users perception of an app, while they are browsing an app store and compare multiple apps to download and possibly to purchase. The ASO tools that provide data on these ratings and reviews, as well as other online sources of app users feedback are Review & Sentiment Analysis tools. Some examples of such companies are Apptentive, AppBot, TheTool that either provide this service along other ASO services or solely focused on providing app developers with information on how people react on their apps.

A/B Testing Tools

Regardless of how thorough app developers think through mobile UI or craft graphics and text for an app marketing copy, chances are they will need to alter it once the app was released on app store. A/B testing is go-to techniques for brands and app developers to define what version of an app marketing copy or UI element performance the best. The type of App Store Optimization tools that provide such service is called A/B Testing Tools.
