SEO Small

Add a favicon

The favicon is a small icon shown in browser tabs, bookmarks, and history, and it is one of the first visual details a returning visitor notices. A missing favicon makes even a polished site look unfinished or, worse, makes it harder to spot among a dozen open tabs.

Why it matters

A missing favicon makes the site look unfinished or untrustworthy in browser tabs, bookmarks, and history (often one of the first things a visitor notices).

How to fix

  1. 1 Create a favicon (ideally in multiple sizes/formats).
  2. 2 Add the corresponding <link rel="icon"> tag(s) to <head>.

Common mistakes

  • Providing only a single small icon size, which looks blurry or gets ignored on high-resolution displays and app-icon contexts (iOS home screen, Android).
  • Linking the favicon with a relative path that breaks on subpaths or when the site is served from a CDN with a different base path.
  • Forgetting to update the favicon link tags after a rebrand, so the old icon lingers due to browser caching.

How to verify

  1. 1 Load the site and confirm an icon (not the browser default) appears in the tab.
  2. 2 View page source and confirm <link rel="icon"> tags reference valid, reachable file paths.
  3. 3 Check the icon at multiple sizes (browser tab, bookmark, mobile home-screen) to confirm it looks correct everywhere it appears.
