In-app advertising lets you display ads within mobile applications, offering marketers direct access to engaged users on their smartphones.
Very often, newbies choose web traffic and pass up in-app networks. Have you ever heard about ad networks such as Smaato, Mopub, or Pubnative? They offer unlimited opportunities to make money by running ads in mobile applications. Let’s learn more about why in-app is so great. This guide explains the benefits of in-app traffic, how it can help you make your campaigns more profitable, and how to optimize in-app ads for better results.
Advantages of In-App Advertising Over Web Traffic
Apps often have several millions of downloads. App audiences can be much bigger than the web audience.
One of the main pros of in-app traffic is the precise source categorization that it provides, which is much more difficult with web. In-app ad networks have more targeting options than regular ones.
Once you know app categories that perform better for you (news, for example), you can create an extended whitelist and target only similar apps. This is much more challenging with web traffic due to diversification of the information on the websites. You have the option to choose only the best performing apps, create whitelists with them and observe the impressive performance of your campaigns.
You also should know that usually smaller screen = better user interaction. In-app ads are ads with better visibility – nothing distracts user attention from your product. You can see below the example how the ad will look like in applications.

How Do You Choose the Best App Categories for Your Ads?
I have a few insights for you:
- Game Apps – work well for game offers. However, some game apps attract more women than men. Check if your in-app ad network allows for gender-based targeting.
- News Apps & Browsers – one-size-fits-all traffic for all types of offers. News apps have diverse and big audiences with different interests. You can run any offer here and it can turn out to be appealing to such a diversified audience. To start, you can try E-commerce, App installs, Nutrition.
- Messaging apps – apps with huge coverage usually. They offer good performance for almost all verticals: E-commerce, Health & Beauty, Finance, Dating, Games etc. Hint: if you run Nutrition and Dating campaigns there is a possibility of Gender and Age targeting in a DSP or ad network.
- Dating Apps – such apps usually block their competitors. That’s why running Dating campaigns in Dating apps is not always possible but again, broad audience and extensive information about users like age or gender, make this traffic a good match for many other products
How Can You Identify the Most Effective Apps for In-App Advertising?
The best way to squeeze the most out of your in-app traffic is to use a dedicated tracker such as Voluum. With the same magic that allows for web-based campaign optimization used on targeted in-app traffic you can achieve outstanding results. Here’s how.
Why Is A/B Testing Important for In-App Ad Campaigns?
The best way to identify effective apps is A/B Split Testing. Create a couple of campaigns with different creatives and headlines. Run these campaigns on different app categories. A/B tests will show you which creative or headline brings you more clicks and conversions. You an do this manually or with Voluum’s AI-based A/B testing.
How Do You Monitor and Improve iCTR in In-App Advertising?
In-app traffic has lower user diversification due to a lack of organic traffic – so pay attention to your iCTR and update creatives and headlines when you see this metric going down.
Not sure what else you can do to increase your iCTR? Check out some of the tips below:
- Write original and compelling headlines. Your ad should be different from your competitor’s ads. We observe many similar creatives and headlines taken from spy tools that stop working after some time as users see them constantly.
- Test your ad. Split testing is the best way to understand what assets are best for each type of offer and traffic source.
- Increase your bid. A higher campaign bid lets you get a better position for your ad. With 1st auction networks (majority nowadays) it is important to increase bids gradually and observe metric improvements.
- Optimize your ad campaigns based on ad space ID (the most granular reporting metric and targeting option). Remember that different ad placements within the app could have very different performance.
For good performance, you should change creatives and headlines very often. Yes, it takes some time but it’s worth it to try if you want to improve your main metrics.
By the way, Voluum provides granular reporting which will help you optimize your campaigns. You can analyze Voluum reports and then pause placements with poor results in your ad network: creatives, apps, ad spaces etc.
