The Favicon is a small icon that appears on the browser tab. When you have many tabs opened in your browser, this icon makes your page stand out. Recently, it is also shown in mobile search results, so it is worth taking advantage of it.
1. Open the Website settings > Favicon
2. Upload an icon. You can upload an icon in PNG format with dimensions of 32x32 or 64x64 and additionally (optional) an icon with dimensions of 512x512 for Apple devices.
3. Save the settings. The icon should appear after refreshing the page in the browser.
