Our feature for speeding up your page load if you use Google Fonts
Does your website belong to huge majority that use Google Fonts?

Why to use a CDN: bridging users and content to improve the loading speed of your web pages
The Content Delivery Network (or CDN) is one of the basics of web performance. By acting as an online ‘relay’, it allows you to create a bridge between content and users. This ensures that the distance information must travel from server to user is as short as possible – and the shorter the distance, the faster the response.
For those who wish to optimise loading times, this technique is often the first port of call. Yet how do you measure its impact? Should you use one CDN or several? And how do you choose between them? Let’s cast the spotlight on this invaluable solution.

Correcting inlining fonts in CSS
Following a healthier, lighter diet also applies to CSS, and the latter will become heavy if it has to put up with base64-encoded fonts.
