Open Measurement 是 IAB 標準，可讓發布商使用第三方可視度評估服務供應商，驗證曝光和點擊評估資料。
Google Mobile Ads SDK 7.43.0 以上版本支援 Open Measurement。這個版本和後續版本會與 Open Measurement (OM) SDK 整合，以利第三方可視度評估。
Google Mobile Ads SDK
支援 OM SDK 1.4 版。
必要條件
*
Google Mobile Ads SDK
7.43.0
以上版本。
導入 Open Measurement
Google Mobile Ads SDK 會自動導入公開評估，並將「Google」做為公開評估合作夥伴名稱，用於透過 Google Mobile Ads SDK 放送的所有廣告。
如要使用第三方可視度評估服務供應商，請在 Ad Manager 使用者介面中設定，並將委刊項設為使用該可視度評估服務供應商。詳情請參閱「設定行動應用程式可視度評估服務供應商」。
確認透明重疊畫面不會遮擋內容
如要避免廣告遭到封鎖，遮蔽廣告的檢視區塊必須符合下列其中一項設定：
遮蔽檢視區塊的背景是否透明並不重要，檢視區塊的 Alpha 和可見度值會決定檢視區塊是否會遮蔽廣告。
如果 Open Measurement SDK 偵測到廣告遭到遮蔽，可視度供應商可能會因此判定曝光無法觀看。如要修正這個問題，請將檢視區塊的 Alpha 設為 0，或將 isHidden 設為 TRUE。
疑難排解
導入 Open Measurement 時，請注意下列事項：
請務必向中介服務合作夥伴確認，他們是否支援所放送廣告的開放式評估功能。
如果廣告遭到重疊的檢視畫面遮蓋，可能無法註冊可視度評估。詳情請參閱「確保透明重疊畫面不會遮擋內容」。
在測試裝置 (包括 iOS 模擬器) 上，系統會偵測到「測試廣告」標籤不會遮蔽廣告檢視區塊。

For more details, see [Configure a mobile app viewability provider](//support.google.com/admanager/answer/9025968).\n| **Note:** Custom native ad formats that don't render a video asset require a custom Open Measurement integration.

For more information, refer to [Ensure that transparent overlays\n are non-obstructing](#obstructing).\n\n- On [test devices](/ad-manager/mobile-ads-sdk/ios/test-ads#enable_test_devices), including the\n iOS simulator, the **Test Ad** label is detected as non-obstructing\n to the ad view."]]
