Ringkasan
Audit ini memeriksa apakah tugas panjang menyebabkan permintaan iklan pertama tertunda atau tidak. Tugas
panjang
didefinisikan sebagai kode JavaScript yang memblokir thread utama selama 50 md atau lebih. Jika tugas
panjang terjadi sebelum permintaan iklan, browser tidak akan dapat mengirimkan
permintaan hingga semua tugas selesai.
Rekomendasi
Periksa tugas yang memblokir permintaan iklan pertama dan selidiki cara untuk
menghapusnya atau mengurangi waktu eksekusinya di bawah 100 md. Beberapa pendekatan untuk
mengurangi waktu eksekusi meliputi:
Mengoptimalkan tugas agar dapat dijalankan lebih cepat
Membagi tugas menjadi bagian-bagian yang lebih kecil, yang masing-masing dijalankan dalam waktu kurang dari 100 md
Menunda tugas hingga permintaan iklan selesai dibuat
Memindahkan tugas dari thread utama melalui pekerja

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"]]
