Requirements for Google App Campaigns ad assets

Let’s take a look at each of these Google App campaign specs:

App campaign text assets

You have to give UAC some ideas for your ad text. The provided text will be used to create your ads in various sequences and formats. When considering text ad elements, keep in mind that they will display in different layouts across various networks.

Potential users could encounter your app in different scenarios—some might be watching a YouTube video, while others could discover it in the Google Play Store. In both instances, the first thing users will notice is your app’s title.

Text asset concludes headlines and descriptions.

  • Headlines: Include a maximum of 5 headlines, with each headline containing 30 characters or fewer.
  • Descriptions: Provide a maximum of 5 descriptions, ensuring each description is 90 characters or fewer.


  • Ensure your headlines/descriptions text has value even without the other.
  • Make your app easy to find on the Google Play Store by optimizing the title – a key factor in App Store Optimization (ASO). This practice is also effective for App campaign.
  • When optimizing your app’s title, keep it straightforward. It should convey the app’s purpose clearly to everyone.
  • Avoid repeating keywords from the app title. Instead, highlight another positive aspect of your app or provide additional information related to the title.

App campaign image assets

If you’re feeling a bit lazy, you can pass on this step. The only necessary ad asset for UAC is text. However, having more control over creative assets is beneficial. With numerous placements, there are various potential image types and dimensions.

Google advises uploading numerous images. Aim to upload as many as you can. For native ads, landscape images are the most valuable format, and for interstitial ads, portrait images work best.

App campaign video assets

To link video ad materials to App campaign, you must first upload videos on YouTube.

The video can be in landscape, portrait, or square orientation. If you don’t have a preferred video for your UAC, Google can use a video from your app’s listing on the Google Play Store.


Remember, the minimum video length required for app campaigns is 10 seconds.

Video creatives often yield better results, attracting more valuable users. If a picture is worth a thousand words, just imagine the impact a video can have on showcasing your app.

Users who watch a video about your app gain a clearer understanding, making them more likely to become engaged users.


  • Orientation: 16:9 (landscape), 2:3 (portrait), and 1:1 (square)
  • Resolutions: 1920×1080 (landscape), 1080×1620 (portrait), 1080×1080 (square)
  • Video duration: 10-30 seconds


  • The more videos, the better. Recommended uploading two squares, two portraits, and two landscapes, testing what could happen, and then changing accordingly due to their efficiency. 
  • Make it short because the video assets on UAC campaigns are not suitable for storytelling. They should be tailored to capture the audience’s attention.

Most common Google App campaign specs

You can upload a maximum of 20 images and 20 videos for your Universal App Campaign (UAC). Different ad placements within the Display Network require specific image dimensions. Here are the most common Google UAC ad dimensions for you:

Most common Google App campaign specs Google App Campaign Specs

Mobile Banner 1 (320 x 50 px)

Mobile Banner 1 (300 x 50 px)

The Google App campaign specs of 300×50 is a small but decent option to make money from mobile traffic on your site. Try it for a few months, and see if it earns you anything while keeping an eye on any potential loss of visitors. These ads are tiny but cost-effective and can reach users at more different points than desktop ads. 

One thing to remember is to keep your UAC’s message clear and graphics simple to get your point across in this small space.

Mobile Banner 2 (320 x 100 px)

Mobile Banner 2 (320 x 100 px)

The 320×100 ad is the bigger brother of the 320×50 ad unit above, known as the Large Mobile Banner. This Google UAC specs is the largest among mobile-specific banner ads, which is a top-performing choice, especially for websites with significant mobile traffic.

While this size may not be a massive revenue driver, it can still monetize mobile ad impressions effectively. Because these ads float at the bottom of the screen, ensure you provide an easy way for users to close them to avoid annoyance. Mega Digital suggests putting in your UAC ad a concise call to action and a clear message and content.

Medium Rectangle (300 x 250 px)

Medium Rectangle (300 x 250 px) Google App Campaign Specs

Google App specs also come in the dimensions: 300×250. This is often referred to as the MPU (Medium Rectangle), which is the most common and top-performing display advertising unit. They are quite expensive because this size allows the ads to appear on various placements: top of the right-hand column and left-hand column or within content. 

When using the medium rectangle size, you should also select both the ad placement and the website as well. If there are many 300×250 ads on the same page, make sure that you’re not paying for several of them simultaneously, unless that aligns with your advertising goals.

Portrait Interstitial (320 x 480 px)

Portrait Interstitial (320 x 480 px)

The 320×480 interstitial ad size is a full-screen mobile ad. This ad typically appears as an overlay on top of website content and is often used as an overlay.

The portrait interstitial size could be very annoying so if you don’t use it smartly, this ad could affect user experience negatively. For your Universal App Campaign, it is therefore advisable to use the 320×480 ad size on larger sites with a big user base to maximize the performance and increase Click-through-rate (CTR).

Landscape Interstitial (480 x 320 px)

Landscape Interstitial (480 x 320 px) Google App Campaign Specs

The 480×320 Banner Ad Unit, or Mobile Landscape Interstitial Ad Unit, is a large ad size that appears full-screen on smartphones when in landscape orientation or within the content of a webpage. It’s an effective choice for branding campaigns because, just like the 320×48 ad size, it is highly viewable yet less annoying. This ad unit is widely used on recipe websites and food blogs.

Leaderboard (728 x 90 px)

Leaderboard (728 x 90 px)

A 728×90 ad is commonly placed at the top of web pages to ensure it’s seen immediately when the page loads. These leaderboard ads are one of the most common sizes in advertising, often considered the second-best ad size after the medium rectangles. When placed at the top of web pages, they are “above the fold”, making them more likely to be noticed and clicked on. 

You can value above-the-fold placements as they tend to have good performance, such as high CTR and engagement rate. However, if these ads are located within content or at the bottom of web pages, they are less likely to be seen by users and consequently earn lower revenues than the top-of-screen ones.

Tablets (1024 x 768 px)

Tablets (1024 x 768 px)

An expandable ad, known as the Tablet Landscape Interstitial Ad (1024 x 768), is designed to appear between content on tablet devices. This spec offers an interactive experience where users can engage with the ad’s content. However, to ensure a positive user experience, you should include a prominently displayed close button allowing users to easily exit the ad. It is also recommended to use this ad sparingly, as frequent interruptions may frustrate users.

Best practices for your Google App campaigns

It’s important for advertisers to optimize various Google App campaign specs on different placements on the Google Display Network. Take a look at some of Mega Digital’s best tips for running a Google App campaign to help you gain a sweet outcome.

Make different creatives for different placements

Google App ad campaigns can appear on various Google platforms, such as Google Search, YouTube, Google Play, and in various apps across the Display Network. As different Google platforms have distinctive features, you may want to take advantage of this by changing your Google App campaign specs accordingly. 

For example, on Google Display Network, you can include longer descriptions for your app because people would read more on websites, blogs,… However, on YouTube, as their main intention is to watch videos, they would scroll past your Google App ad if it is long.

Make different creatives for different placements

Preview your creatives before running 

It’s crucial to test your creatives thoroughly before launching your campaign: the visuals you use, whether they are images, videos, or other formats. Also, make sure that they don’t violate Google’s advertising policy which leads to your ads’ restriction or suspension later on.

If you are not sure what is the best asset for your UAC ad, try A/B testing. You might find through A/B testing that one image vastly outperforms others or that text-only ads result in higher install rates.

Use Google App campaign’s asset reporting

Google has recently updated its asset reporting to allow advertisers to track their App campaigns’ performance. You can use tooltips and various metrics to see insights into “low”, “good”, and “best” asset ratings.

Plus, each tooltip offers actionable recommendations for the specific asset. You can also look at the performance trends in the charts to focus on what works best with users and leave behind what doesn’t. 

Use Google App campaign’s asset reporting Google App Campaign Specs
