If you decide to use Google’s Font API, here are some of the things you’ll be able to take advantage of: [Keep Using HTML] Text Unlike using images or CSS-background-image replacement, using @font-face as a solution to prettier web typography is more SEO-friendly. In addition, it’s an unobtrusive solution, meaning that you don’t need to modify any of your existing content — you just update your CSS stylesheets. [Web Accessible] Because you’re using HTML text and not an image or CSS-background, it doesn’t affect people who use screen readers. [High Uptime Infrastructure and Reduction of Your Web Server’s Duties] By offloading your @font-face needs to Google’s reliable infrastructure, you can be assured of the fact that serving the font files will be fast and that you are relieving your own server’s work.
