Google fonts loading optimisation and caching

Google's page speed test shows only one problem:

Eliminate render-blocking JavaScript and CSS in above-the-fold content Your page has 1 blocking CSS resources. This causes a delay in rendering your page.
None of the above-the-fold content on your page could be rendered without waiting for the following resources to load. Try to defer or asynchronously load blocking resources, or inline the critical portions of those resources directly in the HTML.
Optimize CSS Delivery of the following:
https://fonts.googleapis.com/css?family=Roboto:300,400

The fonts being loaded as fonts.google.com recommends: 

<link href="https://fonts.googleapis.com/css?family=Roboto:300,400" rel="stylesheet">

Within <head /> tag.

As far as i know, there is no way to control google's fonts caching and also, this url's output depends on user agent, so it doesn't make sense to distribute the fonts locally. So, the question is: what do i suppose to do with that? How do i satisfy google's speed test?

Locally hosting the css and fonts speeds up a site by a significant margin -- at least for the "initial page load" view as calculated by pagespeed.

IMHO its not the CDN but the CSS generation. Googlefonts seems to be running a script to generate the unique CSS for the user's browser. Im guessing its swamped by constant traffic and, or written in php. Lol kidding its 2023 it's gotta be node.

Woff has a 100% Browser Compatibility Score as of 2023-03-20 therefore using woff at this point by itself should be fine. The existence of 5 different font formats regardless. Woff2 has a 92 score with low support for IE.

Lacking an IE 11 browser file use the following User-Agent string in curl or other url agent to obtain the css with a link to the woff file.

"Mozilla/5.0 (Windows NT 10.0; Trident/7.0; rv:11.0) like Gecko"

Or use google-webfonts-helper that makes the download job easy.

data:font with fallback needed, load on footer. That will give result like mine :

base64 encoded font

This is example CSS for fallback, else may fail on some device :

@font-face {
 font-family: 'Arial'; /* Do Proper Naming */
 src: url('Arial.eot'); /* For IE 5-8 */
 src: local('?'), /* It is called smile hack to promote CSS to UTF-16 */
 url(data:font/truetype;charset=utf-8;base64,) format('truetype'), /*base64 encoded font IE9, Safari 3.1+ FF 3.5+ Chrome 4.0+*/
 url('Arial.svg#123XYZ') format('svg'); /* iPad, iPhone with OS less than or equal to 4.1 */
 font-weight: normal;
 font-style: normal;
}

I wrote that -- https://thecustomizewindows.com/2013/10/base64-encoding-and-font-css/ That CSS is from an expert developer whom I paid, font developer. Read my guide, test that website's source code, use in the same way.

So far i know ist the best solution today if you use Fontloader. It loads first a short .js script and late the font async.
Tipp: Use font-family: 'Roboto', 'sans serif'; async has the problem the font type is switching after the site is rendered. So the user see a short font switch like a flash. If you use sans serif as fallback the switch is not so big.
Or use .wf-active

Since you cannot control Googles headers (including expiration headers), I can see only one solution – download these two stylesheets and fonts to your own hosting server, change HTML tags accordingly.

Then, you can set expiration headers as you wish.

Download this .woff2 file and save it anywhere on your webserver. Copy & paste this piece of stylesheet into any of your own CSS files or HTML. Change the link from https://fonts.googleapis.com to your new URL.

I guess loading fonts asynchronously can resolve the issue. I found an interesting article, may be it can help you font loading asynchronously.
