In your page, include a link to the Web Font Loader script. This method uses JavaScript, so anyone with JavaScript disabled on their browser will be served the fallback font-families instead. This script loads fonts after the critical path, including any CSS in the element. You can use it with Google Fonts, but also Typekit, Fontdeck, or. What the Web Font Loader does is defer the loading of Google Fonts until after other parts of the page have started to render. The Web Font Loader uses a little sleight-of-hand to make site visitors feel like the page is rendering faster.ĬSS blocks the rendering of the page, which gives impression of slower page speed. (Note: bounce rate is when people leave your site immediately after viewing a single page.) This leads to more conversions, more signups, and more sales. Better page speed on mobile devices means over half of your potential audience will stick around on your website, and not bounce out. But on mobile devices - especially 3G devices, it will deliver much faster page rendering. On good broadband networks, deferring the loading of fonts will only save a little bit of time. When I really starting digging into this problem, one of the first solutions I found was the Web Font Loader - a joint project between Google and Adobe Typekit. So what we want to do is improve our page speed for real users first, but also reduce the number of files on that critical rendering path. Though Page Speed Insights is a good tool, remember that Google still uses what real users see as a metric for judging page speed and user experience. Normally, any CSS file is part of this critical rendering path.
If you are loading Google Fonts via a normal style sheet link in the, then there’s no doubt that link is being looked at a render-blocking file.Īny file that the browser needs to render the page, where it will not show the page without it, is known as part of the critical path. If you’ve ever tested your website on Google Page Speed Insights, you may have seen a message like this:Įliminate render-blocking JavaScript and CSS in above-the-fold content. Web developers who are mindful of user experience, performance, and SEO pay attention to page speed.

The following code snippet gets added to the section of your web document to load the JavaScript and includes the most recent version, which has the added benefit of serving a longer cache duration and shorter loading time: (function() Acting on events You can either write your own code to react to those events, or use CSS styles defined by the library to automatically make styles change when the fonts have finished loading in the browser.
