You don't need a link tag for favicon.ico — browsers check the root directory automatically.
FAQ
Do I still need an ICO file in 2024?
For most modern websites, PNG favicons are sufficient. However, an ICO file provides the best backward compatibility with older browsers and is still recommended as a fallback.
What sizes should the ICO file contain?
A standard ICO file should contain 16x16, 32x32, and optionally 48x48 pixel versions. This covers standard displays, Retina displays, and Windows shortcuts.
Where should I place the ICO file?
Place favicon.ico in your website's root directory (e.g., https://example.com/favicon.ico). Browsers automatically look for it there, even without a link tag.
