What is in-app advertising?

In-app advertising is a mobile advertising strategy used to drive revenues by marketing on apps. By allowing advertisers to advertise their products and services to app users, app publishers drive revenues that ensure their apps stay free to download. Mobile advertisers who use this method often use pay-per-click strategies. And these help with targeting specific audiences.

Mobile advertising revenues are growing every year. And in 2022 and 2023 they’re expected to grow large enough to overtake desktop advertising as the most popular platform. In-app advertising forms a large percentage of this trend and is likely to continue to rise over time.

How does advertising on an app work?

When an in-app ad is well-placed, it increases sales and improves engagement for app publishers. Often, free-to-download apps make their money from publishing in-app ads and running advertiser promotions. But many also offer opportunities to integrate the app user experience, for instance enabling in-app purchases as a feature.

Top In-App Advertising Companies

Advertisers who want to generate revenue from in-app advertising often use mobile app advertisements to generate brand awareness, increase app installs and boost sales.

To show you more, here’s an illustration of how in-app advertising works across all functions:

Model of How In-App Advertising Works 

Advertisers: Marketers will either have their own team members or reach out to an in-app advertising company to create mobile in-app ads. From there, a demand-side platform (DSP) will aggregate campaigns from multiple advertisers, and then offer them up to app publishers.

App publishers: Developers and app owners can integrate with a source of advertiser demand, either direct or with a supply-side platform (SSP) that aggregates publisher supply.

Ad networks: Ad networks bridge the two sides. An ad network connects advertisers and their partners with publishers and their partners. Brands choose an ad network that helps them reach their target audience by working across lots of apps.

What are some in-app advertising formats?

From display ads to incentivized ads, in-app advertising is available in a range of formats that help to attract views and clicks. Here’s a selection of the most popular ones that in-app advertising companies use:

Banner ads

Banner ads are traditional display ads that run across the top of an app page. They often appear in a rectangular shape and take up a section of an app layout. Usually, they remain on the screen and refresh themselves as users interact with an app.

Banner ads are usually available as either CPM (Cost-Per-Mile) or CPC (Cost-Per-Click). And due to the abundance of banner ads, many people suggest their popularity may be in decline.

Interactive video ads

Due to their rising popularity among consumers, more marketers are moving towards using interactive video ads. According to Spiel Creative, almost 80% of marketing professionals saw better online sales when they used interactive video over traditional video.

Some examples of different types of interactive video ads include gamified or playable ads, AR ads, and branched stories.

Rich-Media ads

Rich-media ads offer marketers the chance to blend interactive video ad features with CTA’s and display audio or video. They’re usually more complex to design and execute but they do give marketers the chance to increase brand awareness and boost CTRs.

Interstitial ads

Interstitial ads are another type of interactive ad. But these appear in-between content, so tend to appear during an app’s transitional points. The true benefit of interstitial ads is that they appear as full-screen ads, and encourage users’ full attention.

Native ads

Native ads can be a powerful ad format due to their ability to blend into the content on screen. A good native ad won’t even appear as an ad to a user but will drive engagement rates and interactions by offering valuable content.

Incentivized ads

Also known as reward ads, incentivized ads offer a value exchange in return for action. And studies suggest users are more than 25% likely to convert when they receive valuable rewards or incentives that encourage them to stay on an app.


Offerwalls give app users a choice of incentivized offers that appear as a ‘mini-store’. They often lead to higher app install rates and retention rates as much as 50% higher. They also lead to increased chances of in-app purchases.

How much does in-app advertising cost?

Understanding how much mobile app advertisements cost can help with creating budgets, planning, and deciding which in-app advertising companies are best to approach.

In-app ads pricing models

Because of the wide range of advertising formats. Many types of pricing structures exist when it comes to mobile in-app advertising. And we’ve summarized the key ones below:

  • CPM – Cost Per Thousand or Mile: A low price for advertisers and great for publishers since they need to show the ad 1,000 times to get paid.
  • CPA – Cost Per Action: High CPA rates are effective for publishers who want results in a short space of time. And it’s a low-risk strategy for advertisers.
  • CPV – Cost Per View: Of great benefit to advertisers, since they only pay for seen videos. Publishers only need to show them to get paid.
  • CPC – Cost Per Click: Perfect for advertisers who only pay when someone clicks on their ad. Publishers can sometimes ask for higher rates per click.
  • CPI – Cost Per Install: Lucrative for publishers, and advertisers only pay for committed app users.
  • eCPM: Effective Cost Per Mile serves as a common denominator for all these rates and splits total cost over the total number of impressions.

Advertising in-app has a huge advantage over website advertising. Some reports suggest apps have 3x higher conversion rates over mobile websites, suggesting in-app advertising is more powerful at closing customers.

And there are plenty of other benefits too. Some of these include the following:

Increased revenue from in-app purchases

Consumers tend to engage more and buy more when they download an app. They visit an app more often, and when it comes to e-commerce they also visit physical stores more.

Offerwalls tend to yield higher revenues than other types of advertising formats. Plus, advertisers can expect to generate around $2.50 per completion compared with interstitials which garner around $0.16.

Larger audience exposure

Global app and game downloads totaled over 140 billion in 2021. Plus, the most recent reports suggest time spent on mobile apps makes up around 70% of total US digital media time.

With so many people spending most of their media time on phones, in-app advertising reaches more captive and active audiences.

Personalized audience targeting

In-app advertising companies help with personalized audience targeting based on audience viewing metrics. For instance, they can support advertisers who want to reach a young demographic to reach their target audience on ad networks or direct with publishers.

High CTRs

With its broad reach and targeted approach, mobile in-app advertising tends to garner higher Click-Through-Rates (CTR).

A report by Smaato and Liftoff suggested mobile video in-app ads had 7.5x higher average Click-Through-Rates (CTRs) over display advertising.

Tracking performance

In-app ads make it much easier to track performance since they’re under the control of a publisher’s framework. Unlike website advertising based across multiple sites, platforms, and formats, in-app ads are easier to track.

Captive audiences

Since advertisers are selling products and services to targeted audiences, the audience is more likely to be receptive and open to the types of ads they see.

This also reduces the risk of ad blockers, since in-app advertising companies can help you to target audiences who will want to see your ads.

Improved audience experience

Mobile in-app ads fit to the screen. And this gives audiences a better visual and interactive experience than website ads.
