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......

我过去曾尝试过处理同样的问题,虽然我找不到重定向链和缓存问题的好的解决方案,但我遵循的准则很少:

  1. 仔细考虑每一个外部资源——你真的需要它吗?您真的必须在任何用户交互之前加载它吗?如果是这样 - 它可以从您的服务器中获取吗?在您的示例中,我会将 Google 字体复制到我的服务器。
  2. 永远不要在 CSS 中 @import 东西。它的定义很慢,因为它至少需要两个连续的 HTTP 请求。尝试在 或之前 导入尽可能多的资源,或使用 LESS 或 SCSS 进行预编译。
  3. 忽略广泛使用的资源,例如 Google Analytics。谷歌不可能仅仅因为你使用它们而降低你网站的排名。无论如何,请始终寻找您正在使用的服务的“异步”实现

希望这可以帮助。
