3. Store Listing
Look at the image. Now you know that you need to fill in some information about the app. Be careful while writing keywords for your app. Keywords should be appropriate and related to your app. It is because the right keywords increase the chances of appearing app in app searches.
Have a look at the points below to help in the same.

Many offshore companies provide this type of service as well.
That’s why several businesses like to hire developers from different countries.

6. Fix App Pricing and Distribution
First of all, decide in which countries you are going to launch your app. It is because according to countries the price can vary. Likewise, Google doesn’t support publishing apps for all regions. So, you have to select countries manually where you want to launch it.
If you choose “Free” then you must know that it is permanent. You can’t convert free apps into paid ones. Google doesn’t allow for the same.
If your application is suitable for children under the age of 13 children, select the option “Yes” for the Primary child detected. If not the case, select “No”. Furthermore, select options for allowing or not allowing ads on your app.
7. Publish the Application
You have to go to the section “App releases” to publish the app. After this follow the below steps.
- Choose “Manage Production” and “Edit Release”
- Click on “Review”

After the last step “Confirm”, you can say that you have successfully uploaded the app to the Google play store. But, you will have to wait for some time until the app gets approved. The time for approval varies, sometimes it can approve in just 2 hours, and sometimes it can take days.
It happens because of the type of app people upload. So the app checking criteria are different for the different apps.
