Integrating Leadbolt with Mediation

This guide is intended for publishers who are interested in using Google Mobile Ads mediation with Leadbolt. It walks through the setup of a mediation adapter to work with your current iOS app and the configuration of additional settings.

The following Help Center articles provide background information on mediation:

Add Leadbolt to your project

Integrate ads into your app the same as before. To integrate non-interstitial ads (banner size, leaderboard size, and so on), see Banner Ads. To integrate interstitial ads (full-screen ads that mask all other content), see Interstitial Ads.

The following steps change your ad placement into a mediation placement that can show ads from multiple networks.

  1. Download the adapter and SDK for Leadbolt from the resources above.

  2. Add the downloaded network adapter/SDK in Xcode: right-click on your project and click Add Files to project.

  3. Include any frameworks, compiler flags, or linker flags that Leadbolt require. There's no need to write additional code. Mediation invokes the Leadbolt adapter and SDK as necessary to create ads.

Specify additional request parameters (Optional)

Optionally, you can add targeting information (such as location, birthday, gender, and COPPA preferences) that can be used by networks to serve more finely targeted ads.

Location targeting

If your app already uses CoreLocation, you can use your existing CLLocationManager instance to set the precise location.

Here is an example:


let request = GADRequest()
if let currentLocation = locationManager.location {
      longitude: CGFloat(currentLocation.coordinate.longitude),
      accuracy: CGFloat(currentLocation.horizontalAccuracy))


GADRequest *request = [GADRequest request];
CLLocation *currentLocation = locationManager.location;
if (currentLocation) {
  [request setLocationWithLatitude:currentLocation.coordinate.latitude

Out of respect for user privacy, Google asks that you only specify location if that information is already used by your app.

You can target on birthday and gender as well as location and you can set COPPA tags.

Demographic information

GADRequest provides methods for specifying demographic information like gender and birthday. These are passed along to all networks that accept them. Here is an example:


let request = GADRequest()
request.gender = .female
var components = DateComponents()
components.month = 1 = 1
components.year = 1985
request.birthday = components)


GADRequest *request = [GADRequest request];
request.gender = kGADGenderFemale;
NSDateComponents *components = [[NSDateComponents alloc] init];
components.month = 1; = 1;
components.year = 1985;
request.birthday = [[NSCalendar currentCalendar] dateFromComponents:components]

Set up event notification

To be notified of ad lifecycle events like impressions, you can implement a GADBannerViewDelegate. When using mediation, this delegate is automatically notified of events from Leadbolt. For example, impressions from any ad network are reported through the adViewDidReceiveAd: method of GADBannerViewDelegate.

Ad Events provides instructions on how to register for ad events.

Check the value of adNetworkClassName

You can optionally check the adNetworkClassName property on GADBannerView, which returns the ad network class name of the ad network that fetched the current banner once the adViewDidReceiveAd callback is called:


func adViewDidReceiveAd(_ bannerView: GADBannerView) {
  print("Banner adapter class name: \(bannerView.adNetworkClassName)")


- (void)adViewDidReceiveAd:(GADBannerView *)bannerView {
  NSLog(@"Banner adapter class name: %@", bannerView.adNetworkClassName);

Similarly, for interstitials, check the adNetworkClassName property on GADInterstitial inside interstitialDidReceiveAd:


func interstitialDidReceiveAd(_ ad: GADInterstitial) {
  print("Interstitial adapter class name: \(ad.adNetworkClassName)")


- (void)interstitialDidReceiveAd:(GADInterstitial *)interstitial {
  NSLog(@"Interstitial adapter class name: %@", interstitial.adNetworkClassName);
For ads returned from AdMob, adNetworkClassName returns GADMAdapterGoogleAdMobAds. For ads fetched via custom events, it returns GADMAdapterCustomEvents.
