# Add a favicon to every page
Google displays favicons next to search results on mobile devices, making your brand immediately recognisable in the SERP. A missing or inaccessible favicon prevents Google from showing it, reducing visual brand presence in search.
## Quick Reference
- Provide a `<link rel="icon">` pointing to a favicon file; Google uses it to identify your site in search results
- Serve the favicon via HTTPS, ensure it is publicly accessible (not blocked by robots.txt), and at least 48×48px for Google's use
- Include both an ICO fallback and SVG/PNG versions for broad browser and device compatibility
## Check
In the page `<head>`, look for `<link rel="icon">` or `<link rel="shortcut icon">` elements. Verify: (1) The href points to an accessible URL (returns 200, not blocked by robots.txt). (2) The file is at least 48×48px (for Google Search use). (3) A PNG or SVG version is provided alongside the ICO fallback. (4) The favicon is accessible over HTTPS.
