Google Pagespeed“第三方使用”问题

Question

I have optimized my website in every possible way, but when I am testing performance in google pagespeed tool it shows "Third-Party Usage 4 Third-Parties Found"

I have used defer / async loading external scripts and used preconnect also but this error is still showing.

What should I do???

Here are full details of the performance check:

For clarity this is not an error message - anything under the 'diagnostics' section is for your information to help you diagnose any outstanding performance issues.

It does NOT affect your score directly.

The only way to avoid this is to bundle the 4 items together into a single file and include them as a script served from your own server.

I do this with Google Analytics (so I can avoid Sub Resource Integrity errors in Mozilla Observatory) by downloading the file each night and caching it locally.

I would not worry about it at all, your performance problems come from the other 460kb of JS you have in your concated.js file so if you want to improve performance, start by looking there to remove as many libraries as you can.

Also the CSS you have inlined to minimise critical request chains is gigantic, try optimising that to only include 'above the fold' CSS as that is all that is needed.
