How does the VP accelerator work?

Question

Search Engine Optimization

Hello! There was a problem with the optimization of the site, it gave out 60 on mobile phones and 88 on PC. I began to dig on the Internet, how to optimize. Basic optimization was done (photo optimization, code compression, gzip caching, etc.). But still it wasn't enough. For it is loaded too with the help of metrics of 5-6 types.

I found the Accelerator plugin on the Internet and installed it. Noticeably improved speed with forced SLOW 3g. Yes, and statistics began to show at least 95-100.

But, maybe he uses some extraneous scripts? who deceive the PageSpeed ​​statistics? And how to be displayed on metrics and SEO

In the same place, it seems to be written in the description that it somehow cunningly caches.
You can basically tweak DB caches and HTTP caches without it to get good results.
Although xs how it's done in wp, at least in normal code it's a little more complicated than elementary.
