Test and select a fast WordPress theme
One of the most important aesthetic designs you will make on your WordPress site is which theme to use, but it's also one of the most important decisions you can make for site speed. A lot of themes have additional little pieces of junk and code that come along, and many little files that come along for users to load. Luckily, it's fairly easy to switch WordPress themes. From the WordPress admin, look under appearance and themes, and select a theme with features that are important to you.
