Thumbnail Ad

This article will go through all the steps required to display a Thumbnail Ad in your application.

Thumbnail Ads are small rectangle ads that are displayed as overlays to your application content. They are closable and draggable by the user, and can be used to (i) monetize your application through new incremental inventories and (ii) push cross-promotion campaigns.

Unlike our other ad formats, there is no equivalent ad format in AdMob mediation. To integrate Thumbnail Ads, the Ogury SDK uses Google Mobile Ads SDK custom events to present them as banner to the mediation.

You must create a dedicated AdMob banner ad unit and mediation group for the Thumbnail Ad in order to prevent undesired side-effect (blank banner, etc.).


You have registered an application on your Ogury Dashboard. If not, please refer to the Getting Started section before the next steps.

Step 1: Create an Ogury Thumbnail Ad ad unit

In all the following code samples, we will refer to this Ad unit id by using the string AD_UNIT_ID.

Step 2: Create a dedicated AdMob Banner ad unit

  • Go to your AdMob dashboard.

  • Go to the list of ad units and click on the Add ad unit button.

  • Click on Banner.

  • Configure the banner ad unit as following:

    • Set the ad unit name: Thumbnail Ad.

    • Click on Advanced settings link to unfold them.

    • In Automatic refresh setting, select Disabled.

    • In eCPM floor, set the global eCPM floor to $1000.

The eCPM floor must be set to prevent AdMob to serve an ad on this dedicated ad unit.

We recommend to disable auto-refresh to avoid having Thumbnail Ads popping in front of the user every X seconds.

Step 3: Create a dedicated Mediation Group

In order to display Ogury Thumbnail Ad through AdMob mediation, you need to configure a Custom Event for Ogury in a dedicated mediation group.

  • Go on the Mediation Group page.


  • Select Banner as ad format.

  • Set a Name for the mediation group.

  • In Ad units section, click on ADD AD UNITS.

  • Select the dedicated ad unit you created above.

  • Click on ADD CUSTOM EVENT, in the Waterfall section

  • Enter Ogury as Label, set an eCPM and click on CONTINUE.

For eCPM, you need to set the value that you agreed with your Ogury Account Manager.

  • Next to the name of your Thumbnail ad ad unit, enter the following configuration and click on DONE:

Class Name:



  • Click on SAVE.

Integrate the Thumbnail Ad

Step 1: Instantiate a Thumbnail Ad

You need to change the code to instantiate the banner ad from adMob as following:

let thumbnailAd = OguryThumbnailAdForGoogleMobileAds(adUnitId: "YOUR_ADMOB_AD_UNIT_ID")

Step 2: Load a Thumbnail Ad

To start loading an ad, call the load method:


The ad is loaded with a default max size of 180x180 points. The max size can be changed by following the instructions in this section.

Since it may take a few seconds to fetch the ad resources (video, image, ...) from the network, you should call the load method as soon as possible after getting the user's consent.

Ideally, you should implement one of the two following examples depending on your use case:

  • Call the load method right after the setupWithAssetKey method in the ViewController:

import UIKit
import OgurySdk

class ViewController: UIViewController {

    var thumbnailAd: OguryThumbnailAdForGoogleMobileAds?
    override func viewDidLoad() {
        self.thumbnailAd = OguryThumbnailAdForGoogleMobileAds(adUnitId: "YOUR_ADMOB_AD_UNIT_ID")

        OguryAds.shared()?.setup(withAssetKey: "OGY-XXXXXXXXXXXX") { error in
  • Call the load method in the viewDidLoad of your other ViewController

override func viewDidLoad() {
    self.thumbnailAd = OguryThumbnailAdForGoogleMobileAds(adUnitId: "YOUR_ADMOB_AD_UNIT_ID")

Additionally, if you want to follow the lifecycle of the Thumbnail Ad, you can attach a delegate.

Step 3: Show a Thumbnail Ad

To display the ad call the show function: self)

Thumbnail Ads are displayed bottom-right aligned, with a margin of 20 points on the right and 70 points on the bottom. More details on how to set the thumbnail position can be found in this section.

By default the Thumbnail Ad remains on screen while the user is navigating between View Controllers of your application. A Thumbnail Ad is displayed in a ViewController if bundle identifier of the ViewController corresponds to the main bundle of application.

You can customize where Thumbnail Ads are displayed in this section.

Step 4: Test your integration

Ogury exclusively serves ads to users who have given consent. It is essential to have responded to a valid TCFv2 consent form before conducting any tests.

As our algorithm works with personified targeting, you may not receive any ad while testing your application.

You can test your integration by adding the suffix _test to your interstitial ad unit id, for more details go to Test your implementation page.

Note that if you have just registered your application in the Ogury Dashboard, it will take around 15 minutes until you can successfully load an ad.

Advanced Topics

Customize a Thumbnail Ad size

In order to control the thumbnail size, call load method with maxWidth and maxHeight parameters:

self.thumbnailAd.load(with: CGSize(width: maxWidth, height: maxHeight))

maxWidth and maxHeight parameters define the maximum size that the Thumbnail Ad will take on the screen. Both values are in points.

We recommend to use maxWidth = 180 and maxHeight = 180 to improve the readability of the content of the Thumbnail Ad.

Example: when given maxWidth= 180 and maxHeight= 180, the Ogury SDK may decide to display a 16:9 video ad inside. In this case the Thumbnail Ad size will be 180x101 points to match the ratio of the 16:9 video.

The following constraints apply on the values you can pass to these parameters:

  • maxWidth and maxHeight must not be greater than the size of the screen.

  • maxWidth and maxHeight must be greater than or equal to 101 points.

  • longest side, either maxWidth or maxHeight, must be greater than or equal to

    180 points.

Customize Thumbnail Ad position

To set the Thumbnail Ad position, call the show method with OguryRectCorner and OguryOffset parameters:

self.thumbnailAd.setOguryRectCorner(rectCorner, offset: OguryOffset(x: xMargin, y: yMargin))

The show method takes the following parameter:

  • rectCorner: the corner based on which the Thumbnail Ad will be positioned. The OguryRectCorner enum has the following values:

    • OguryTopRight

    • OguryTopLeft

    • OguryBottomLeft

    • OguryBottomRight

  • anOguryOffset: the distance from the corner to the Thumbnail Ad

    • xMargin: distance from the x axis to the Thumbnail Ad. Value must be in points.

    • yMargin: distance from the y axis to the Thumbnail Ad. Value must be in points.

Customize where the Thumbnail Ad is displayed

Thumbnail Ad remains on screen while the user is navigating between ViewController of your application.

By default, a Thumbnail Ad is displayed in an ViewController only if this bundle identifier are the main bundle of application.

You can override these default settings using whitelists and blacklists.

Whitelist bundles

You can increase the number of whitelisted bundles where Thumbnail Ads are displayed and stay on screen. This can be useful if you have ViewController provided by a library like a game engine, in this case you need to whitelist the bundle associated to this library.

Call the setWhitelistBundleIdentifiers method to whitelist bundles:

self.thumbnailAd.setWhitelistBundleIdentifiers(["com.example.bundle", "com.example.bundle2"])

Blacklist View Controllers

You can prevent Thumbnail Ads from being displayed on a given ViewController by using the setBlacklistViewControllers method:

self.thumbnailAd.setBlacklistViewControllers([NSStringFromClass(TermsAndConditionsViewController.classForCoder()), NSStringFromClass(SettingsViewController.classForCoder())])

When the user navigates to a ViewController that is not in a whitelisted bundle or that is explicitly blacklisted, the Thumbnail Ad is hidden and paused. It comes back on the screen when the user navigates back to a ViewController that is allowed.


The Ogury SDK provides OguryThumbnailAdDelegate to listen to the lifecycle of a Thumbnail Ad instance.

To register a OguryThumbnailAdDelegate, add the following code just after instantiating the OguryThumbnailAdForGoogleMobileAds:

self.thumbnailAd.delegate = self

The OguryThumbnailAdDelegate exposes the following methods:



The SDK is ready to display the ad provided by the ad server.


The ad has been displayed on the screen.


The as has been clicked by the user.


The ad has been closed by the user.


The ad failed to load or display. The error parameter contains the reason of the failure. All error codes are detailed in the section below.

Error codes

When an ad fails to load or to be displayed, the SDK will call the didFailOguryTAdWithError callback with one of error code defined in OguryAdsError:
