這項稽核會評估可歸因於廣告相關指令碼的封鎖時間時間長度。廣告相關指令碼封鎖 JS 執行緒的時間長到使用者能察覺，因而直接影響輸入延遲或內容載入，這項擷取作業會擷取執行時間。
建議
在廣告 JS 封鎖時間中，最重要的因素就是同時載入的廣告數量。我們的建議如下：

如要瞭解封鎖時間的定義方式，請參閱 Total Blocking Time (總封鎖時間) 一文
如果指令碼是廣告代碼，或由第三方網站標示為「廣告」指令碼，系統就會將其視為廣告相關。

This captures time where the JS thread is\nblocked by an ad-related script for long enough to be noticeable by users as it\ncan directly affect input delay or content loading.\n\nRecommendations\n---------------\n\nThe most important factor in ad JS blocking time is how many ads are being\nloaded at once. Our recommendations are:\n\n- [Load fewer ads at once or reduce ad density](https://developers.google.com/publisher-ads-audits/reference/audits/viewport-ad-density), if feasible\n- [Lazy load ads below the fold](https://developers.google.com/publisher-ads-audits/reference/audits/ads-in-viewport)\n- [Reduce batch sizes if using Single Request Architecture (SRA) in GPT](https://developers.google.com/publisher-tag/guides/publisher-console-messages#TOO_MANY_SLOTS_IN_SRA_REQUEST).\n\nMore information\n----------------\n\nTo learn how blocking time is defined, see this article on\n[Total Blocking Time](https://web.dev/lighthouse-total-blocking-time/#what-tbt-measures)\n\nA script is considered to be ad-related if it is either an ad tag or labeled as\nan \"ad\" script by [Third Party Web](https://github.com/patrickhulce/third-party-web). \n[View audit source](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/lighthouse-plugin-publisher-ads/audits/total-ad-blocking-time.js) [Improve this article](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/docs/audits/total-ad-blocking-time.md) [Report an issue](https://github.com/googleads/publisher-ads-lighthouse-plugin/issues/new?labels=documentation&template=documentation-feedback.md&title=Documentation+feedback%3A+total-ad-blocking-time.md)\n\n\u003cbr /\u003e"]]
