Genel bakış
Bu denetim, ilk reklam isteğinin uzun görevler nedeniyle gecikip gecikmediğini kontrol eder. Uzun görev, ana iş parçacığını 50 ms veya daha uzun süre engelleyen JavaScript kodu olarak tanımlanır. Bir reklam isteğinden önce uzun görevler gerçekleşirse tarayıcı tüm görevler tamamlanana kadar isteği gönderemez.
Öneriler
İlk reklam isteğini engelleyen görevleri inceleyin ve bunları kaldırmanın veya yürütme sürelerini 100 ms'nin altına indirmenin yollarını araştırın. Yürütme süresini kısaltmaya yönelik yaklaşımlardan bazıları şunlardır:
Görevleri daha hızlı yürütülecek şekilde optimize etme
Görevleri, tek tek 100 ms'nin altında yürütülecek daha küçük parçalara ayırma
Görevleri reklam istekleri yapılana kadar erteleme
Görevleri bir çalışan aracılığıyla ana iş parçacığının dışına taşıma

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"]]
