避免使用会阻塞渲染的资源

概览
此项评估旨在找出会延迟加载广告代码库的资源（具体来讲，就是脚本和样式表）。这些是在广告代码库开始加载之前已请求和收到的资源。减少在代码加载之前请求的资源数量可加快广告加载速度。
建议
此项评估的结果详情包含一个列表，其中列出了所有会延迟代码加载的脚本和样式表。目标是减少此列表中的条目数量，使其尽可能接近 0。以下是一些关于执行此操作的提示：
- 在网页的
<head> 中更早地加载广告代码库。
- 将对核心功能至关重要的脚本和样式表直接内嵌到 HTML 中。
- 使用
async 或 defer 属性标记非关键脚本。
- 通过媒体查询将样式拆分为不同的文件，并使用
media 属性仅在需要时加载它们。
支持以下广告代码库脚本：
| 媒体库 |
脚本 |
| AdSense |

pagead2.googlesyndication.com/pagead/show_ads.js

To improve ad loading speed, reduce the number of resources requested before tag loading. Key actions include loading ad tag libraries earlier, inlining critical scripts/stylesheets, marking non-critical scripts with `async` or `defer`, and using the `media` attribute for conditional stylesheet loading. Supported ad tag libraries include AdSense and Google Publisher Tag, each with specific script URLs.

These are resources that were\nrequested and received before ad tag libraries began loading. Reducing the\nnumber of resources requested prior to tag load will speed up ad loading.\n\nRecommendations\n---------------\n\nThe details of this audit contain a list of all scripts and stylesheets that are\ndelaying tag load. The goal is to reduce the number of entries in this list as\nclose to 0 as possible. Some tips for doing this include:\n\n- Loading ad tag libraries earlier in the `\u003chead\u003e` of the page.\n- Inlining scripts and stylesheets critical to core functionality directly into your HTML.\n- Marking non-critical scripts with the `async` or `defer` attributes.\n- Separating styles into different files by media query and using the `media` attribute to load them only when needed.\n\nMore information\n----------------\n\nThe following ad tag library scripts are supported:\n\n| Library | Script(s) |\n|----------------------|-------------------------------------------------------------------------------------------------------------|\n| AdSense | `pagead2.googlesyndication.com/pagead/js/adsbygoogle.js` `pagead2.googlesyndication.com/pagead/show_ads.js` |\n| Google Publisher Tag | `googletagservices.com/tag/js/gpt.js` `securepubads.g.doubleclick.net/tag/js/gpt.js` |\n\n[Rendering Blocking Resources](https://developers.google.com/web/tools/lighthouse/audits/blocking-resources) \n[View audit source](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/lighthouse-plugin-publisher-ads/audits/ad-render-blocking-resources.js) [Improve this article](https://github.com/googleads/publisher-ads-lighthouse-plugin/tree/HEAD/docs/audits/ad-render-blocking-resources.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-render-blocking-resources.md)\n\n\u003cbr /\u003e"]]
