應用程式必須先呼叫 MobileAds.Initialize()，初始化 Google Mobile Ads SDK 之後，才能載入廣告。這項操作只需執行一次，最佳時機是應用程式啟動時。
以下範例說明如何呼叫 MobileAds.Initialize()：
MobileAds.Initialize((InitializationStatusinitstatus)=>
{if(initstatus==null){Debug.LogError("Google Mobile Ads initialization failed.");return;}Debug.Log("Google Mobile Ads initialization complete.");// Google Mobile Ads events are raised off the Unity Main thread. If you need to// access UnityEngine objects after initialization,// use MobileAdsEventExecutor.ExecuteInUpdate(). For more information, see:// https://developers.google.com/admob/unity/global-settings#raise_ad_events_on_the_unity_main_thread});

This needs to be done only once, ideally at\napp launch.\n| **Warning:** Ads can be preloaded by the Google Mobile Ads SDK or mediation partner SDKs upon calling `MobileAds.Initialize()`. If you need to obtain consent from users in the European Economic Area (EEA), set any request-specific flags, such as `tagForChildDirectedTreatment` or `tag_for_under_age_of_consent`, or otherwise take action before loading ads. Verify you do this before initializing the Google Mobile Ads SDK.\n\nHere's an example of how to call `MobileAds.Initialize()`: \n\n MobileAds.Initialize((InitializationStatus initstatus) =\u003e\n {\n if (initstatus == null)\n {\n Debug.LogError(\"Google Mobile Ads initialization failed.\");\n return;\n }\n\n Debug.Log(\"Google Mobile Ads initialization complete.\");\n\n // Google Mobile Ads events are raised off the Unity Main thread.

You're now ready to implement an ad. AdMob\noffers a number of different ad formats, so you can choose the one that makes\nfor the best user experience.\n\nBanner\n\nBanner ad units display rectangular ads that occupy a portion of an app's\nlayout. They can refresh automatically after a set period of time. This means\nusers view a new ad at regular intervals, even if they stay on the same\nscreen in your app. They're also the simplest ad format to implement. \n\n[Implement banner ads](/ad-manager/mobile-ads-sdk/unity/banner)\n\nInterstitial\n\nInterstitial ad units show full-page ads in your app. Place them at natural\nbreaks and transitions in your app's interface, such as after level completion\nin a gaming app. \n\n[Implement interstitial ads](/ad-manager/mobile-ads-sdk/unity/interstitial)\n\nNative\n\nNative ads are ads where you can customize the way assets such as headlines and\ncalls to action are presented in your apps. By styling the ad yourself, you can\ncreate a natural, unobtrusive ad presentations that can add to a rich user\nexperience. \n\n[Implement native ads](/ad-manager/mobile-ads-sdk/unity/native)\n\nRewarded\n\nRewarded ad units enable users to play games, take surveys, or watch videos to\nearn in-app rewards, such as coins, extra lives, or points. You can set\ndifferent rewards for different ad units, and specify the reward values and\nitems the user received. \n\n[Implement rewarded ads](/ad-manager/mobile-ads-sdk/unity/rewarded)"]]
