Mobile Banner Ads - A Pillar of Mobile App Monetization

Mobile banner ads remain one of the foundational monetization tools available to mobile app publishers. Here’s how developers can use them more effectively.

Every mobile app has its own unique monetization strategy — some rely exclusively on in-app purchases (IAPs) or subscriptions, while others incorporate mobile ads. But to stay resilient in today’s economy, a diversified approach is your best bet. So can you really afford to ignore the opportunity of mobile banner ads?

Mobile Banner Ads - A Pillar of Mobile App Monetization

Banner ads may not be the most complex ad format, but they have staying power for a reason. It’s telling that brands like Amazon and Postmates lean on mobile banner ads to drive sales, while established apps like AccuWeather and Waze incorporate them into their monetization strategies. At Vungle, we’ve invested big in banner ads, too. Last year, we rolled out some major updates that allow publishers to fill impressions even faster, with enhanced cache optimization.

In this guide, we’ll explore the ins and outs of banners ads, including how to decide if they’re the right fit for your mobile app. Let’s dive in!

What are mobile
banner ads?

Mobile banner ads are small, rectangular advertising images displayed on a portion of the mobile screen. Banner ads are also the oldest of all ad formats, and while they may have originated on desktop, they have also become one of the most prevalent forms of in-app advertising. These ads can be static, animated, or video, typically sticking to the top or bottom of the screen through portions of the session. Mobile banner ads can be deployed via SDK, or programmatically, with the option to refresh if users do not interact with it for a certain period.

In the U.S., most mobile banner ads generate between $0.50 and $1.20 per 1,000 impressions served. While these may not be the same flashy CPMs as newer formats like rewarded videos, mobile banner ads play a critical role in any comprehensive monetization strategy. They are non-invasive and a great fit for brand advertisers looking to build awareness.

Why use mobile

Why use mobile banner ads?

Banner ads have a poor reputation in some circles — particularly when it comes to desktop web banners — thanks to banner blindness. This phenomenon occurs when users become familiar with standard ad placements on a web page and learn to ignore anything deployed in those spaces.

What not everyone realizes is that banner blindness is avoidable. It typically occurs when ads are boring, scammy, or irrelevant to the user. While it can be challenging to curate quality ad content via programmatic, some SDK networks (like us!) set a high bar to ensure brand safety and optimal performance. Furthermore, resourceful monetization managers have found that creating a “pop-in” effect by toggling banner ads to display after other elements have already been rendered can produce greater engagement levels compared to loading them along with the rest of the UI. With the right partnership, mobile banner ads still have value.

With the right creative and targeting optimizations, mobile banner ads consistently deliver value for publishers and advertisers alike



For publishers looking to monetize their apps, mobile banner ads represent a valuable placement that is easy to implement. Again, diversification is key. Publishers should consider pairing mobile banner ads with other placements, such as rewarded video. Using several different types of ads maximizes revenue while preserving, or in some cases, enhancing the user experience.

When deployed through a high-quality SDK network, mobile banner ads consistently generate incremental revenue from brand advertisers. Mobile banner ads are typically used to monetize free utility apps that see frequent, short-term sessions from users. For this reason, they can be especially effective in casual/hypercasual games, but they can be comparably valuable in mid/hardcore gaming apps, dating apps, social media apps, service apps, and more.



Mobile banner ads are a simple yet cost-effective method of promoting your app or brand. They place a lower demand on ad spend than other formats, yet they guarantee a high degree of visibility — partly because apps tend to display a single ad placement at a time. What’s more, mobile banner ads rarely suffer from the “banner blindness” of desktop ads due to their novelty and persistence on-screen, resulting in higher engagement.

Mobile banner ad sizes

Mobile banner ads come in various sizes, but generally take up a small portion of the screen, unlike full-screen interstitials. This helps advertisers promote their apps with minimal disruption to the user interface.

In terms of technical specifications, the following banner image sizes tend to be the most effective:

Smartphone banner ads

  1. 320x50

    The IAB refers to this banner size as the 6x1 Horizontal. It’s also colloquially known as “micro-banner” because it typically shows up discreetly at the top or bottom of a smartphone interface.

  2. 300x50

    This is the minimum banner size recommended for smartphones. While 320x50 is standard, some publishers may prefer this smaller size for greater subtlety.

Tablet banner ads

  1. 728x90

    The IAB refers to this banner size as the 8x1 Tile. On some platforms, you may also hear it referred to as a “leaderboard” ad because of the large screen real estate it consumes. This mobile banner ad format is ideal for advertisers that wish to include more detail and prominent

MREC banner ads

  1. 300x250

    MREC or medium rectangle banner ads are a larger display unit that typically appears interstitially or within content feeds. For example, these ads may appear after a user completes an action or navigates to a new part of the app. Where there is enough screen real estate, publishers may choose to display MRECs above or below content in lieu of an interstitial. On content streaming apps, MRECs can also be placed during breaks in the content stream. Such placements see strong engagement because they do not take over the full screen, but still include striking visuals, or even video.
