What are Mobile
and InApp Ads?

In-app advertising is a monetisation strategy for mobile publishers on Google, in which app developers get paid to serve advertisements within their mobile app. In-app advertising allows advertisers to reach engaged and relevant audiences with advanced data and contextual targeting options. 

There are various types of in-app ads that can be displayed within mobile apps:

  1. Banner ads: These are rectangular images with texts or graphics that appear at the top or bottom of the screen. They are usually less intrusive and can be easily dismissed by the user1.
  2. Interstitial ads: These are full-screen ads that cover the entire app content and appear at natural transition points, such as between levels or pages. They are more immersive and engaging, but can also be annoying if shown too frequently.
  3. Rewarded video ads: These are video ads that offer users some incentives or rewards for watching them, such as extra lives, coins, or premium content. They are popular in gaming apps and can increase user retention and loyalty.
  4. Native ads: These are ads that match the look and feel of the app content and blend in seamlessly with the app environment. They are less disruptive and more relevant to the user’s interests.
  5. Offerwall ads: These are ads that present users with a list of offers or tasks that they can complete in exchange for some in-app rewards. They are similar to rewarded video ads, but offer more choices and flexibility to the user.

Why would you
advertise on

Some of the benefits of in-app advertising are:

  • It allows advertisers to reach users who spend more time on different apps and are more engaged with the app content.
  • It offers higher click-through rates and conversions than traditional web advertising, as the ads are more relevant and personalized to the user’s interests and preferences.
  • It enables advertisers to use rich data and contextual targeting options, such as location, device, gender, age, and app category32.
  • It helps publishers monetize their apps and keep their content free for users, increasing downloads and retention.
  • It is less affected by ad blockers and privacy regulations, as the ads are integrated within the app environment and rely on opt-in user data.

89% of phone time is devoted to using an app.


Nearly 60% of all ad revenue comes from mobile.


On average 31% clicks on mobile in app advertisements.


The revenue of In App ads is projected on 205 billion USD in 2023.
