Favicon
A favicon is a website icon, a small logo used to identify a website in search engines. It is visible in search engine snippets, in browser tabs next to the web page title, and in bookmarks .
Size
16x16 or 32x32 pixels. Search engines generally accept both options. Choose the most appropriate one to ensure good readability across different browsers and devices.
Format
The favicon must be saved in the .ico format - the most common and supported by all major browsers.
Filter
Yandex and Google may manually review your website if it imitates someone else's brand. For example, if you've received a complaint or there are other possible reasons for stealing someone else's favicon. Search engines consider the content second-rate—counterfeit, theft, plagiarism. There are also legal requirements if you use a registered logo/icon of a well-known company but aren't an official distributor of the brand (e.g., Nike, Adidas, Armani, BMW, Mercedes, Samsung, Apple).
File name
The favicon file must be named "favicon.ico" and located in the root folder.
Location in code
The TOP SEO Boss example uses two tags: one with the attribute rel="icon"and one with the attribute rel="apple-touch-icon". This is done to ensure compatibility across different devices and browsers.
The attribute hrefspecifies the path to the favicon image file (usually with the .ico extension, but .png or .jpg formats can also be used).
Proper favicon display on all devices and browsers is important; check manually after a month. Favicon appearance may be delayed due to caching, so after a change on the server, it may take time for all users to see the favicon.

I'm not teaching bad things here and I'm not encouraging plagiarism, however, it may be needed for good purposes, for a beautiful link exchange.
I have a standard favicon from my logo. I used my website as an example. Finally, change the domain you want to copy it from.
