A favicon is a small icon that represents your website. It appears in browser tabs, search results, bookmark lists and mobile home screens. Typically 16×16 or 32×32 pixels in size, this tiny graphic helps users quickly identify your site among multiple open tabs or saved bookmarks. A well-designed and easy to recognise favicon can strengthen brand recognition and improve click-through rates (CTR).
