I did this already. However it is new according to Google that they show a favicon in the search results. Google says I have to add a code to the header:
Add a <link> tag to the header of your home page with the following syntax:
<link rel=”shortcut icon” href=”/path/to/favicon.ico”>
rel
Can be any of the following strings:
“shortcut icon”
“icon”
“apple-touch-icon”
“apple-touch-icon-precomposed”
href
The URL of the favicon. Can be a relative path (/smile.ico) or absolute path (https://example.com/smile.ico), but must be in the same domain as the home page.
HOW CAN I ADD A CODE TO THE HEADER`?
