Common problems I see in the Webflow forums;
Why isn't my favicon showing in my tab?
Assuming you've uploaded your favicons in your General site config, and published your site, you should be fine.
If you're still not seeing it, clear your browser cache.
Why isn't Google showing my Favicon in search results?
Sometimes it can be difficult to get Google to pickup your Webflow favicon, even though it matches Google's requirements ).
Here are some approaches that may help-
- Create an Organization JSON-LD with your company name, referencing your Webflow-hosted favicon URL.
- Setup a Google Business Profile, and add your icon as your business logo. Although this is typically associated with Google Maps and local listing, you do not need an address to do this.
- Setup Google Adwords, and add your icon as your business logo. You likely do not need to actually run Ads for this.
- Create a favicon sized at a multiple of 48x48, and add it to your site-wide head.
- Create an SVG icon and add it to your site-wide head.
- If Google is being especially stubborn and your icon is correctly defined, you can try reporting the problem directly through Google's search result pages. Find your website in results, and then look for the 3-dot menu, which allows you to report problems with SERPs listings.
What does Google see?
Google has a special URL that allows you to see the favicon it has cached for your domain.
https://www.google.com/s2/favicons?domain=
DOMAIN
&sz=
SIZE
Replace the domain and icon size ( in pixels ) with your own, e.g.
https://www.google.com/s2/favicons?domain=sygnal.com&sz=48
Why isn't Google showing my Favicon on mobiles?
In 99% of the situations I've seen, most likely, you have a 16x16 icon specified in your favicons. Historically, Google hasn't liked this, and ends up not showing any favicon at all.
Although this is no longer listed, I'd still avoid it as a best practice.

Google looks for and updates your favicon whenever it crawls your home page. If you make changes to your favicon and want to inform Google about the changes, you can request indexing of your site's homepage. Updates can take a few days or longer to appear in search results.
Why isn't my favicon showing for password-protected sites / pages?
SOLUTION: Most likely, you can define your favicon directly in the HEAD of your login page. [ untested ]
