Page Summary
-
Native ads are integrated into a platform's UI using standard components and styled to match the app's design.
-
After loading, the app is responsible for displaying native ad content using the provided ad object and its assets.
-
Implementing native ads involves loading the ad using the SDK and then displaying the ad content within your app.
-
Always use test ad unit IDs during development and testing to prevent invalid activity on live ads.
-
The
GADAdLoaderclass and its delegates are used to load native ads and receive notifications about their status.
Native ads are ad assets that are presented to users through UI components that are native to the platform. They're shown using the same classes you already use in your storyboards, and can be formatted to match your app's visual design.
When a native ad loads, your app receives an ad object that contains its assets, and the app—rather than Google Mobile Ads SDK—is then responsible for displaying them.
Broadly speaking, there are two parts to successfully implementing native ads: Loading an ad using the SDK and then displaying the ad content in your app.
This page shows how to use the SDK to load native ads.
Prerequisites
- Complete the Get started guide.
Always test with test ads
When building and testing your apps, make sure you use test ads rather than live, production ads.
The easiest way to load test ads is to use our dedicated test ad unit ID for native ads on iOS:
ca-app-pub-3940256099942544/3986624511
It's been specially configured to return test ads for every request, and you can use it in your own apps while coding, testing, and debugging. Just make sure you replace it with your own ad unit ID before publishing your app.
For details on Google Mobile Ads SDK test ads, see Enable test ads.
Load ads
Native ads are loaded with the
GADAdLoader
class, which send messages to their delegates according to the
GADAdLoaderDelegate
protocol.
Initialize the ad loader
Before you can load an ad, you have to initialize the ad loader.
The following code demonstrates how to initialize a GADAdLoader:
Swift
Replace nativeAdUnitID with your ad unit ID.
Objective-C
Replace kNativeAdUnitID with your ad unit ID.
You'll need an ad unit ID (you can use the test ID), constants to pass in the
adTypes array to specify which native formats you want to request, and any
options you want to set in the options parameter. The list of possible
values for the options parameter can be found in the Setting Native Ad
Options page.
The adTypes array should contain
this constant :
Implement the ad loader delegate
The ad loader delegate needs to implement protocols specific to your ad type.
For native ads, the GADNativeAdLoaderDelegate protocol includes a message
that's sent to the delegate when a native ad has loaded.
Swift
func adLoader(_ adLoader: AdLoader, didReceive nativeAd: NativeAd) {
// To be notified of events related to the native ad interactions, set the delegate property
// of the native ad
nativeAd.delegate = self
// TODO: Display the native ad.
}
Objective-C
- (void)adLoader:(GADAdLoader *)adLoader didReceiveNativeAd:(GADNativeAd *)nativeAd {
// To be notified of events related to the native ad interactions, set the delegate property
// of the native ad
nativeAd.delegate = self;
// TODO: Display the native ad.
}
Request ads
Once your GADAdLoader is initialized, call its loadRequest: method to
request an ad:
Swift
adLoader.load(Request())
Objective-C
[self.adLoader loadRequest:[GADRequest request]];
The
loadRequest:
method in
GADAdLoader
accepts the same
GADRequest
objects as banners and interstitials. You can use request objects to add
targeting information, just as you
would with other ad types.
Load multiple ads (optional)
To load multiple ads in a single request, set the
GADMultipleAdsAdLoaderOptions
object when initializing a GADAdLoader.
Swift
Objective-C
The number of ads per request is capped at five, and it's not guaranteed that the SDK will return the exact number of ads requested.
Returned Google ads will all be different from each other, though ads from reserved inventory or third-party buyers are not guaranteed to be unique.
Don't use the GADMultipleAdsAdLoaderOptions class if you're using mediation,
as requests for multiple native ads don't work for ad unit IDs that have been
configured for mediation.
Determine when loading has finished
After an app calls loadRequest:, it can get the results of the request using
calls to:
adLoader:didFailToReceiveAdWithError:inGADAdLoaderDelegateadLoader:didReceiveNativeAd:inGADNativeAdLoaderDelegate
A request for a single ad will result in one call to one of those methods.
A request for multiple ads will result in at least one callback to the above methods, but no more than the maximum number of ads requested.
In addition, GADAdLoaderDelegate offers the adLoaderDidFinishLoading
callback. This delegate method indicates that an ad loader has finished loading
ads and no other ads or errors will be reported for the request. Here's an
example of how to use it when loading several native ads at one time:
Swift
func adLoaderDidFinishLoading(_ adLoader: AdLoader) {
// The adLoader has finished loading ads.
}
Objective-C
- (void)adLoaderDidFinishLoading:(GADAdLoader *)adLoader {
// The adLoader has finished loading ads.
}
Handle failed requests
The protocols extend the GADAdLoaderDelegate protocol, which defines a
message sent when ads fail to load.
Swift
func adLoader(_ adLoader: AdLoader, didFailToReceiveAdWithError error: any Error) {
// The adLoader failed to receive an ad.
}
Objective-C
- (void)adLoader:(GADAdLoader *)adLoader didFailToReceiveAdWithError:(NSError *)error {
// The adLoader failed to receive an ad.
}
Get notified of native ad events
To be notified of events related to the native ad interactions, set the delegate property of the native ad:
Swift
// Set the delegate before making an ad request.
adLoader.delegate = self
Objective-C
// Set the delegate before making an ad request.
self.adLoader.delegate = self;
Then implement
GADNativeAdDelegate
to receive the following delegate calls:
Swift
func nativeAdDidRecordImpression(_ nativeAd: NativeAd) {
// The native ad was shown.
}
func nativeAdDidRecordClick(_ nativeAd: NativeAd) {
// The native ad was clicked on.
}
func nativeAdWillPresentScreen(_ nativeAd: NativeAd) {
// The native ad will present a full screen view.
}
func nativeAdWillDismissScreen(_ nativeAd: NativeAd) {
// The native ad will dismiss a full screen view.
}
func nativeAdDidDismissScreen(_ nativeAd: NativeAd) {
// The native ad did dismiss a full screen view.
}
func nativeAdWillLeaveApplication(_ nativeAd: NativeAd) {
// The native ad will cause the app to become inactive and
// open a new app.
}
Objective-C
- (void)nativeAdDidRecordImpression:(GADNativeAd *)nativeAd {
// The native ad was shown.
}
- (void)nativeAdDidRecordClick:(GADNativeAd *)nativeAd {
// The native ad was clicked on.
}
- (void)nativeAdWillPresentScreen:(GADNativeAd *)nativeAd {
// The native ad will present a full screen view.
}
- (void)nativeAdWillDismissScreen:(GADNativeAd *)nativeAd {
// The native ad will dismiss a full screen view.
}
- (void)nativeAdDidDismissScreen:(GADNativeAd *)nativeAd {
// The native ad did dismiss a full screen view.
}
- (void)nativeAdWillLeaveApplication:(GADNativeAd *)nativeAd {
// The native ad will cause the app to become inactive and
// open a new app.
}
Best practices
Follow these rules when loading ads.
Apps that use native ads in a list should precache the list of ads.
When precaching ads, clear your cache and reload after one hour.
Don't call
loadRequest:again on aGADAdLoaderuntil the previous request finishes loading, as indicated byadLoaderDidFinishLoading:.Limit native ad caching to only what is needed. For example when precaching, only cache the ads that are immediately visible on the screen. Native ads have a large memory footprint, and caching native ads without destroying them results in excessive memory use.
Destroy native ads when no longer in use.
Display your ad
Once you have loaded an ad, all that remains is to display it to your users. Head over to our Native Advanced guide to see how.
