Visão geral
Esta auditoria mede a quantidade de tempo de bloqueio
atribuível a scripts relacionados a anúncios. Isso captura o tempo em que a linha de execução de JS é
bloqueada por um script relacionado a anúncios por tempo suficiente para ser perceptível pelos usuários, já que
pode afetar diretamente o atraso na entrada ou o carregamento do conteúdo.
Recomendações
O fator mais importante no tempo de bloqueio do JavaScript do anúncio é quantos anúncios estão sendo
carregados de uma vez. Nossas recomendações são:
Para saber como o tempo de bloqueio é definido, consulte este artigo sobre
Tempo total de bloqueio.
Um script é considerado relacionado a anúncios se for uma tag de anúncio ou rotulado como um script de "anúncio" pela Web de terceiros.

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"]]
