Many webmasters are obsessed with achieving 100 score on Google PageSpeed, GTmetrix, and other website testing tools. Depending on the structure of your website, plugins you have installed, and scripts you use, it may take a bit of work to achieve that score. There are simple steps that you can take to make your site faster regardless (e.g. hosting fonts locally). OMGF for WordPress can help with that. It is a handy plugin that preloads fonts to reduce CLS.
OMGF lets you unload fonts that are not used by your theme or plugins. It ensures text remains visible during webfont load. The pro version lets you replace font families with system fonts to speed up load time. It has even more features, including multisite support.
