Reducing CSS font

My site’s rating was 32, I made several changes to it, removed the icons and inserted svg as instructed by a friend here on the forum, and another was the reduction of CSS fonts.
I removed the link, compiled and pasted the fonts css into a fonts.css file, the end result was a rating of 80 for cell phones.
Very tricky to have to make these modifications to optimize site loading, but it’s been helpful.
This was the original source file imported from google fonts.

I excluded some of the variations and kept only this one below, on the site I use three types of fonts with variations, but I only presented one of them.

What’s really the kicker on this is that Google junk is usually what causes half the issues we get for rating. Jump thru them hoops! Lol

You could try adding the following to your head to see if it loads faster:

<link rel="preconnect" href="https://fonts.gstatic.com">

Another option is to host the fonts yourself and see if this gives an improvement to load times.

To be honest, I have a little of both, hosted and not and the sites I have made so far with BSS 5 have been in the A range. I don’t think your fonts are the issue if things are that slow, and I’ve done all different ways of images too and it hasn’t affected it all that much. I’d look further into what it may be if I were you as even if these things did cause a little bit, it would most likely be not very noticeable unless you’re using humongous images and not resizing them, that would do it for sure.

Just letting you know how it’s working for me if that helps any.

It is a purchased model, I am redoing it on the bss to see if it will get better.
