How the favicon of the site is displayed in the search
We will immediately note that such a small icon will be useful both for tabs and for the search engine. Google tests favicion in the search results on the desktop version of the resource, and in the mobile version, in the results, it is displayed on a permanent basis. You can find it to the left of the site address itself. It acts as an additional guide for choosing a link, and if you don't have a favicon yet, consider creating one. A site without a picture will quickly get lost among the bright links of competitors.
