因此,我正在努力解决由于客户端站点中使用的外部服务而导致的排名下降。我几乎已经完成了我认为可以控制的所有事情,包括解决渲染阻塞问题。
但是在所有网站上都像一条红线一样运行的一件事是,由于浏览器缓存和外部资源的重定向建议,包括谷歌自己的 analytics.js,YSlow 和 PageSpeed 最多只能停留在 D 范围内的排名。
现在我知道其中一些资源可能能够在本地移动,但通常,尤其是在重定向链的情况下 - 这似乎是一项艰巨的任务。
这是一个疯狂的重定向链的示例:

似乎能够对此做些什么会大大提高分数,因为这是唯一需要解决的问题。所以我的问题是 - 可以做些什么呢?
有没有人尝试过解决方案,例如在源生成后通过覆盖重定向链的代理重写 url或获取资源并使用修改后的标头传递它们?
这是值得的还是这些页面分数只是被忽略了?
什么是合理的选择?
为一个加载的问题道歉......
