Builder Basic Settings: Favicon
The Favicon Settings section allows you to control the Favicon settings for your site.
Favicons are the small images that are used in a variety of ways, but the one you're probably most familiar with is the small image used next to the title of a site in browser tabs. This makes it easy for people to quickly identify specific sites just by skimming the images on the tabs.
You can select from a few built-in options, upload your own image to use, or just disable the Favicon entirely, For more information about each of these favicon options, just hover over the question mark on the right.
