MoPub Format Unification Early Access Program
The 5.8 release simplifies the ad unit creation process for publishers by automating information picked up by the SDK. At the same time, the release increases flexibility in creative sizes, enabling more DSPs to bid on an impression.
Creating ad units is faster and simpler.
We have simplified the process of creating an ad unit in the Publisher UI. Instead of creating a separate ad unit for every size, screen orientation, and device type within an ad format, you will now simply select from the available ad formats. We have simplified the selections to five choices: banner, medium rectangle, fullscreen, native, and rewarded video. The SDK will collect the remaining data automatically.
The SDK now collects the ad size dimensions in real time.
The SDK can collect the available ad real estate for any ad format. For banner ads, publishers can specify the maximum dimensions via the iOS, Android, and Unity SDK integration APIs; and for fullscreen ads, the SDK will dynamically collect the safe area based on the device.
Additional creative sizes are now supported.
You are no longer limited to the few standard ad size dimensions offered in the Publisher UI. Our existing formats now support multiple additional creative sizes. The SDK collects the available dimensions for an ad display and our ad server then automatically identifies eligible creative sizes. In addition to the existing sizes, the below new sizes are added to the formats.
- New sizes for Banners: 300x50, 468x60, 970x90, 970x250
- New sizes for Medium Rectangles: 336x280
- New sizes for Fullscreen: 320x568, 300x600, 360x640, 300x1050, 568x320, 640x360
Extended supply for non-native display opportunities.
Enabling additional creative sizes for ad formats positions us to meet demand from DSPs and advertisers to serve more creative sizes than we have in the past. Bid requests now contain all acceptable creative sizes for the ad unit, and DSPs can respond with any one of the sizes listed, including the newly added sizes.
End-user experience improves.
Video ads will now display in the correct device orientation as picked up by the SDK, so the user can enjoy a better fullscreen experience, without the need to reorient their devices.
Affected Components and Processes
The process of creating a new ad unit is now streamlined.
- You no longer need to provide ad size specifications.
- You no longer need to create a separate ad unit for each size.
- You no longer need to specify device type (phone or tablet).
- You no longer need to specify device orientation for fullscreen ads.
The SDK automatically collects device orientation and sends it to the ad server.
For banner ads, the publisher passes to the SDK the maximum real estate for banner ads via newly added API calls (refer to step 2 of the Participate in the Early Access Program section).
For fullscreen ads, the SDK collects the available real estate from the device, taking into account not only device size, but physical device specifics that vary across models, such as notches and other physical features. The SDK then sends these dimensions to the ad server, which optimizes the available Marketplace demand.
After the ad server identifies eligible creative sizes, it sends them to DSPs inside a format array as part of the bid request. The MoPub platform optimizes the available Marketplace demand and creative displays based on the available ad format sizes.
Bid Requests and Responses with DSPs
Bid requests will now contain a format array containing a subset of acceptable widths and heights, when applicable, enabling DSPs to respond with a creative for any of the dimensions listed. Bid responses from participating DSPs will include the dimensions of the creative the DSP is proposing.
MoPub encourages DSPs to adopt the new format array into their systems. Doing so increases the inventory available to DSPs and the number of impressions their creatives can fill. We are working with our demand partners as an increasing number of them integrate this new format.
Participate in the Early Access Program
To participate in the Format Unification Early Access Program:
If you are using an earlier version of the MoPub SDK than 5.8, upgrade your MoPub SDK to version 5.8.
To take advantage of format unification for banner ads, pass banner sizes in your API calls to the MoPub SDK:
Instead of calling
moPubView.loadAd();as before, you will now pass in the size by calling
This has not changed. Continue to pass in the banner size as before:
If you know the size of the banner you’d like to request, call
If you don’t know or have the size of the banner you’d like to request, and you’d like to use a constant, call
loadAdWithMaxAdSize:and pass in one of the recognized MoPub ad size constants as listed here.
If you would like to use the frame as the maximum ad size, pass in the
Instead of calling
MoPub.CreateBanner(adUnitId, position)as before, you will now pass in the size by calling
MoPub.RequestBanner(bannerAdUnit, position, maxAdSize);.
Upgrade mediation adapters if you are partnering with AppLovin or Facebook. The adapter versions listed here are required for compatibility with MoPub SDK version 5.8.
Refer to adapter upgrade instructions for AppLovin.
Refer to adapter upgrade instructions for Facebook.
Reach out to your account team or to MoPub support to access UI features for format unification.
Going forward, you will always create new ad units as unified ad units in the Publisher UI.
a. In the Apps tab’s App details page, click New ad unit. The New ad unit screen has changed to require less information:
b. As discussed in the Publisher UI section of this document, there are various fields you are no longer required to fill in. For the remaining fields, follow the instructions in our documentation to create a new ad unit.
Convert legacy ad units to unified ad units in the Publisher UI:
a. In the Apps tab’s Ad unit details page, click Edit ad unit. The new Edit ad unit page now has a convert option.
b. Click Convert to unified ad format. You can see back at the App details page, which lists all of your app’s ad units, that legacy ad units have a different appearance from unified ad units:
c. Repeat steps 6a and 6b for every legacy ad unit.
Note: Direct-Serve ad units cannot be converted to a unified format.
What is the MoPub Format Unification Early Access Program?
The MoPub Format Unification Early Access Program offers publishers a sneak peak at our new release aimed to both simplify the ad unit creation process and increase the demand for impressions. The Early Access Program begins on August 22, 2019 and ends on September 16, 2019, at which point all publishers will have general access to this release.
If you are interested in trying this new version before it becomes publicly available, contact your MoPub account team and we will provide you access to the new Publisher UI and SDK.
What are the advantages of using unified ad units?
Unified ad units are simpler and faster to create and maintain, and allow you to extend your existing supply by supporting additional ad sizes for DSPs.
Do mediated networks support flexible width and height?
This varies from network to network. Facebook Audience Network supports flexible width; Google AdMob supports both flexible width and height. Other networks only serve standard-sized creatives, which will be centered in the MoPub views if the views are larger than the creatives.
Going forward, for any new ad unit, you will not need to create multiples to account for size or orientation differences.
