In the Google Mobile Ads SDK Android version 11.2.0 and iOS version 7.21.0, we added multiple native ads, a new feature for AdMob Native Ads Advanced. This feature lets you load up to five unique native ads with a single request. If you're showing native ads in a scrolling feed, this will allow you to get a batch of ads different from one another. It also means fewer network calls, which improves latency.
If you're displaying multiple native ads in a feed and loading ads one by one, converting to the new API should be fairly straightforward.
First, make a decision about how many ads you wish to fetch in one request. This is a function of how frequently you display ads in your feed. If you request five ads, AdMob will return the top five ads, ordered by eCPM value. If only three ads are available for the ad unit, only three ads will be returned.
iOS Implementation
Before initializing your ad loader, you need to create an instance of GADMultipleAdsAdLoaderOptionsand set the numberOfAdsproperty. Then include this object in the array of options when calling GADAdLoader's initializer:
GADMultipleAdsAdLoaderOptions
numberOfAds
GADAdLoader
override func viewDidLoad() { super.viewDidLoad() let multipleAdsOptions = GADMultipleAdsAdLoaderOptions() multipleAdsOptions.numberOfAds = 5 adLoader = GADAdLoader(adUnitID: YOUR_AD_UNIT_ID, rootViewController: self, adTypes: [GADAdLoaderAdType.nativeContent, GADAdLoaderAdType.nativeAppInstall], options: [multipleAdsOptions]) adLoader.delegate = self adLoader.load(GADRequest()) }
When requesting multiple native ads, you will still get individual callbacks when each ad is loaded. For example, for an app install ad you will have a callback to -adLoader:didReceiveNativeAppInstallAd:, and for a content ad -adLoader:didReceiveNativeContentAd:. This way you don't need to change the way the ads are received and shown.
-adLoader:didReceiveNativeAppInstallAd:
-adLoader:didReceiveNativeContentAd:
To determine when ads have finished loading, there are two new APIs available:
loading
true
false
GADAdLoaderDelegate
adLoaderDidFinishLoading:
Android Implementation
The Android implementation is similar to iOS. There's a new method on AdLoader, loadAds() which accepts the number of ads to load. There's also a new isLoading()method that indicates whether a request is currently in progress.
AdLoader
loadAds()
isLoading()
For a detailed walkthrough of the implementations, see the AdMob Native Ads Advanced implementation guides (iOS| Android). If you have any questions about this feature in the Google Mobile Ads SDK, please drop us a line at the developer forum.
