How to grow an app on google play store?

1. Run a Google test constantly

Google Play provides you the option to set up and test different variants of your app listing, including:

• your icon
• Functional Graphics
• screenshot
• Video
• Short Description
• Full Description

Running the experiment is free and can be rewarded by increasing the daily activity users of your application.

There are a lot of ways in which you can set up and run in less than 10 minutes. Even without having an expertise or resources to create new graphics, anyone can make some changes to their short description or complete description. Here are some ideas for a brief and complete description of the test:

Brief description:

• Use social proof, such as using numbers or sorting your categories
• Use several keywords to resonate with visitors
• Try some brand slogans

Detailed Description:

• Try formatting the description text
• Try using your application or FAQ section
• Test the different variants of the first 5 lines, which is the most prominent line in your complete description.

2. Be careful not to put the keyword
Google is the king of search ranking algorithms, good at sniffing out keywords stuffing; If Google thinks you deliberately exaggerate the number of keywords in your description, your rankings may be affected.

3. Use your title to place one or two of your top but highly relevant keywords
The title is one of the best places to rank the keywords, which is true for Android and IOS apps. It is also a great signal to tell users who see your application in search results and what your application is. Select one or two related keywords to describe what your application is and include those in your title in this format:

4. Select 3-5 Competitors and study what they are doing
Pick some of your top contenders to study how they describe their applications and attract users. Study what their screenshots are, what keywords they use, what selling points they sell, and what users are saying. This information will be useful not only to provide you with ideas about keywords or message passing, but you will also know how to differentiate between your application and your competitors to better attract visitors.

5. Localize your list
If your application is available on a global level, why not localize your list to make it more generic? You can translate your apps list using Google Translate, but Google also offers a choice from a localized vendor to purchase localized translations. For any country where you see a significant increase in installation and revenue (or your preferred KPI), consider localizing the strings in your application and optimizing to retain them.
