What is a favicon
A favicon is a small icon that represents a website in browser tabs, bookmarks, and other browser UI elements. The word favicon is short for "favourite icon" and was first introduced by Internet Explorer in 1999 as a way to brand bookmarked pages.
Modern browsers display favicons in many places: browser tabs, the address bar, bookmarks folders, browser history, and search results. On mobile devices, browsers show favicons when users save a website to their home screen as a shortcut or install a Progressive Web App.
A complete favicon set includes multiple image sizes and formats to ensure your website icon looks sharp across all browsers, operating systems, and devices — from desktop computers to smartphones and tablets.
Why favicons matter for SEO and branding
Favicons are a key part of website branding. A recognisable favicon helps users quickly identify your website among multiple open browser tabs and in their bookmarks list.
Search engines such as Google may display favicons in search results, especially on mobile devices. A well-designed favicon makes your result stand out and reinforces brand identity at a glance.
Key benefits of using a proper favicon:
- Improves brand recognition in browser tabs and bookmarks
- Makes your site easier to identify among multiple open tabs
- Can increase click-through rate in search results
- Ensures your site looks professional across all devices
