A simple tool to check whether your favicon is eligible to be shown in Google search results and help with branding and CTR.

Favicon checker rules

Verify if your website's favicon meets Google's requirements for display in search results. This tool checks if your home page has:

  • Proper favicon markup in the HTML
  • Accessible favicons not blocked by robots.txt
  • Square favicons larger than 48x48px
  • Valid favicon image format

Make your site stand out in search results with favicons

A favicon is that small icon next to your website's name in browser tabs. But it's more than just a tiny image - it's a powerful branding tool that can make your site stand out in Google search results and help users recognize your brand instantly.

When Google shows favicons in search results, they give your site a visual identity that catches the eye. This small image can:

  • Make your results more noticeable in a crowded page
  • Help users quickly find your site when they return
  • Build brand recognition over time
  • Increase click-through rates from search results
  • Make your site look more professional

What our tool checks

Our favicon checker looks at several key factors that determine whether Google will show your favicon in search results:

Proper HTML setup

The tool verifies that your site has the correct favicon tags in your HTML. Google looks for specific link elements like:

  • rel="icon" for standard favicons
  • rel="shortcut icon" for legacy support
  • rel="apple-touch-icon" for iOS devices

Image requirements

We check if your favicons meet Google's specifications:

  • Square shape (1:1 aspect ratio)
  • At least 48x48 pixels (though 8x8 is the minimum)
  • Proper image format (ICO, PNG, GIF, or JPG)
  • Clear, recognizable design

Technical access

The tool confirms that search engines can access your favicon by checking:

  • If the favicon URL is accessible
  • Whether robots.txt blocks access
  • If the image loads correctly
  • Whether the URL is stable

Best practices for search-friendly favicons

Size and format

  • Make your favicon at least 48x48 pixels
  • Use a square aspect ratio
  • Choose PNG format for best quality
  • Keep the file size small for fast loading

Design tips

  • Keep it simple and recognizable
  • Use your logo or brand initial
  • Ensure it looks good at small sizes
  • Match your brand colors
  • Test how it looks in search results

Technical setup

  • Place the favicon file in your root directory
  • Use consistent URLs
  • Allow search engines to access the file
  • Include proper HTML tags
  • Test on multiple devices

Common favicon issues

Missing favicon

If Google can't find your favicon, your site will show a generic icon in search results. Make sure you have proper favicon tags in your HTML.

Wrong size

Favicons that are too small or not square might not display correctly. Use at least 48x48 pixels for best results.

Blocked access

Check your robots.txt file to ensure it's not blocking access to your favicon or image directories.

Poor quality

Blurry or pixelated favicons look unprofessional. Use high-quality images and test how they look at different sizes.

Inconsistent branding

Your favicon should match your site's branding. Don't use different icons across your site.

Frequently asked questions

Google needs to recrawl your site to pick up favicon changes. This can take anywhere from days to weeks.

Can I have different favicons for different pages?

Google only supports one favicon per domain or subdomain. You can't set different favicons for individual pages.

Do I need multiple favicon sizes?

While Google requires just one size, it's good practice to provide multiple sizes for different devices and uses.

Meeting all requirements makes your site eligible for favicon display, but Google doesn't guarantee they'll always show it.

Can I use a transparent favicon?

Yes, but ensure it looks good on both light and dark backgrounds since search results can appear in both modes.

Should I update my favicon often?

No, keep your favicon stable. Frequent changes can confuse users and require Google to recrawl your site.

What's the best favicon format?

PNG works well for modern browsers while maintaining good quality. ICO files provide legacy support.

Do subdomains need separate favicons?

Yes, each subdomain can have its own favicon, but subdirectories use the main domain's favicon.
