Visão geral
Essa auditoria verifica se a primeira solicitação de anúncio está atrasada por tarefas longas. Uma
tarefa longa é
definida como um código JavaScript que bloqueia a linha de execução principal por 50 ms ou mais. Se ocorrerem tarefas longas antes de uma solicitação de anúncio, o navegador não poderá emitir a solicitação até que todas as tarefas sejam concluídas.
Recomendações
Analise as tarefas que estão bloqueando a primeira solicitação de anúncio e investigue formas de
removê-las ou reduzir o tempo de execução para menos de 100 ms. Algumas abordagens para
reduzir o tempo de execução incluem:
Como otimizar tarefas para execução mais rápida
Dividir tarefas em partes menores, que são executadas individualmente em < 100 ms
Adiar tarefas até que as solicitações de anúncios sejam feitas
Como remover tarefas da linha de execução principal usando um worker

Esta auditoria exibe as 10 tarefas mais longas por tempo de execução, classificadas por horário de início (crescente).

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"]]
