我正在开发一个网站，该网站使用小部件来显示来自TripAdvisor网站的评论等。但是，根据Google的Page Speed Analytics，他们正在损害我网站的性能。具体来说，CSS和JavaScript都没有缩小，图像也没有优化。在这种情况下（据我所知），CSSNano等构建工具不能用于第三方。通常，根据我的经验，当从CDN或类似程序加载第三方脚本时，可以使用缩小版本，但我不认为在这种情况下就是这种情况。我查看Google's Page Speed Module的服务器，但我有IIS，我不肯定它会工作（因为脚本是从TripAdvisor提取而不是托管在我的服务器上）。
作为参考，小部件呈现如下：

我开始认为根本不可能优化小部件。但是，他们似乎确实对网站造成了显着影响，所以我想看看是否有人对这些小部件或类似的东西有相关经验。
感谢。

我现在正在处理这个问题。从站点中删除小部件可使站点速度提高60％。您无法以任何有意义的方式更改其小部件代码以进行改进，因此最好定期截取其当前呈现的视图并将其裁剪为您放置在网站上的小.png。它无论如何都不清楚它是否为人们提供了那么多可信度的价值。
