이 감사에서는 첫 번째 광고 요청이 긴 작업으로 인해 지연되고 있는지 여부를 확인합니다. 긴 작업은 기본 스레드를 50ms 이상 차단하는 자바스크립트 코드로 정의됩니다. 광고 요청 전에 긴 작업이 발생하면 브라우저에서 모든 작업이 완료될 때까지 요청을 실행할 수 없습니다.
권장사항
첫 번째 광고 요청을 차단하는 작업을 검토하고 이를 삭제하거나 실행 시간을 100ms 미만으로 줄이는 방법을 조사합니다. 실행 시간을 줄이는 몇 가지 방법은 다음과 같습니다.
더 빠르게 실행되도록 작업 최적화
작업을 각각 100ms 미만으로 실행되는 작은 청크로 분할
광고 요청이 이루어질 때까지 작업 지연하기
작업자를 통해 기본 스레드 외부로 작업 이동
추가 정보
이 감사는 실행 시간을 기준으로 가장 긴 작업 10개를 시작 시간별로 정렬하여 표시합니다 (오름차순).

A\n[long task](https://developer.mozilla.org/en-US/docs/Web/API/Long_Tasks_API) is\ndefined as JavaScript code that blocks the main thread for 50ms or more. If long\ntasks occur before an ad request, the browser will be unable to issue the\nrequest until all of the tasks complete.\n| **Note:** Although 50ms is the commonly accepted long task threshold, this audit will only flag tasks that block the main thread for 100ms or more. This is because shorter tasks generally have a smaller impact on ad loading.\n\nRecommendations\n---------------\n\nExamine the tasks that are blocking the first ad request and investigate ways to\nremove them or reduce their execution time below 100ms. Some approaches to\nreducing execution time include:\n\n- Optimizing tasks to execute faster\n- Splitting tasks into smaller chunks, which individually execute in \\\u003c 100ms\n- Delaying tasks until after ad requests are made\n- Moving tasks off of the main thread via a worker\n\nMore information\n----------------\n\nThis audit displays the top 10 longest tasks by execution time, sorted by start\ntime (ascending).\n\n[Are long JavaScript tasks delaying your Time to Interactive?](https://web.dev/long-tasks-devtools) \n\n[Inspect Network Activity In Chrome DevTools](https://developer.chrome.com/docs/devtools/network/) \n[View audit source](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/lighthouse-plugin-publisher-ads/audits/ad-blocking-tasks.js) [Improve this article](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/docs/audits/ad-blocking-tasks.md) [Report an issue](https://github.com/googleads/publisher-ads-lighthouse-plugin/issues/new?labels=documentation&template=documentation-feedback.md&title=Documentation+feedback%3A+ad-blocking-tasks.md)\n\n\u003cbr /\u003e"]]
