Favicon Checker

Where favicons appear

Browser tabs, bookmarks, mobile home screens — and Google mobile search results, which is why favicons are now an SEO checklist item, not just polish.

Recommended modern setup

• `favicon.ico` (32×32) at the site root as the universal fallback
• An SVG favicon: resolution-independent, supports dark-mode media queries
• `apple-touch-icon.png` (180×180) for iOS home screens
• Google Search requires a multiple of 48px (48, 96, 144…)

Problems this checker commonly finds

• Favicon blocked by robots.txt so Google can't fetch it
• `<link rel="icon">` pointing to a path that 404s
• Cache staleness: browsers cache favicons aggressively — after replacing one, change the filename or add a query string to force the update
