Google Updates Favicon Requirements for Search Results

Google has recently updated its favicon guidelines, setting clearer requirements on size, aspect ratio, and resolution. These small changes are all about enhancing the look and clarity of favicons in search results.

What is a Favicon?

A favicon is a tiny icon that represents a website, usually appearing next to the site's title in browser tabs, bookmarks, and search results. It's often a simplified, recognizable image that makes your site easier to identify at a glance. For businesses, it’s a small but valuable piece of branding that users recognize instantly.


The Update: Aspect Ratio and Size Requirements

In this update, Google has introduced two key requirements:

  1. 1:1 Aspect Ratio: Favicons displayed in Google Search must be square—meaning the width and height should be equal. This is to make sure the favicon appears clean and uniform, with no squishing or stretching.
  2. Size Requirements: The minimum favicon size is now 8x8 pixels. However, Google recommends aiming for at least 48x48 pixels to keep your favicon crisp and clear on all display types, especially high-resolution screens. A larger size allows for better rendering and a sharper image, making your site’s icon stand out in search results.

Why These Changes?

Google’s updated guidelines reflect the actual display needs of modern devices and resolutions. With more people browsing on a wide variety of screen sizes, favicons benefit from being higher resolution. Consistency in the favicon’s square shape also means it will display correctly, ensuring better brand recognition across devices.


Additional Favicon Guidelines to Keep in Mind

To make sure your favicon shows up in search results without any issues, remember the following:

  • One favicon per site: Each domain (https://example.com) and subdomain (https://blog.example.com) can have a unique favicon, but subdirectories like (https://example.com/blog) cannot.
  • Make it crawlable: Ensure that your favicon file and the home page are crawlable.
  • Represent your brand: Choose a favicon that visually reflects your brand for quick recognition.
  • Stable URL: Keep your favicon URL consistent—don’t change it frequently.
  • Avoid inappropriate imagery: Google won’t display favicons with offensive or inappropriate content.

While following all these guidelines improves your chances, Google adds one final note of caution:

“A favicon isn't guaranteed to appear in Google Search results, even if all guidelines are met.”

Conclusion

Incorporating these updates and adhering to Google’s favicon guidelines can help ensure your favicon is presented accurately across devices and in search results. A small update, yes, but an important one that keeps your branding clear, consistent, and instantly recognizable.
