Favicon is a tiny website icon. It appears in the address bar of your browser next to the page title, in the bookmarks bar, in tabs and other interface elements.
To change the favicon, go to Site Settings → SEO → Edit Favicons.
Note. You can only upload a favicon in the .ico format. We recommend using 32 x 32 px file size.
Along with the Favicon you can also upload an Apple touch icon in .png format to be displayed in Safari tabs, mobile and desktop bookmarks, as well as an icon and a background for tiles on Win10.
To make sure a newly assigned favicon is correctly displayed, you may need to clear and restart the browser cache as some browsers, including Chrome, store previous favicons in the cache.
