這項指標並不代表發生特定問題。而是用來找出有待改善的部分，並追蹤長期的改善情形。
我們的目標是縮短發出第一個廣告請求所需的時間。只要確保其他更具體的稽核項目都通過，應該就能為這項指標帶來重大影響。請特別注意，影響廣告代碼載入時間和第一個廣告請求的延遲時間 (從載入廣告代碼) 的稽核，可能會影響這項指標。
這項指標會將最早對下列其中一個項目提出且記錄到的請求，視為「第一個廣告請求」：
| 媒體庫 |
主機 |
路徑 |
| AdSense |
googleads.g.doubleclick.net |
/pagead/ads |
| Google 發布商廣告代碼 |
securepubads.g.doubleclick.net |
/gampad/ads |
避免常見的 GPT 導入錯誤
可縮短網頁延遲的廣告代碼設定最佳做法
