How can favicons be displayed in Yandex services?
Any favicon that is accessible to the robot and meets the requirements of the service where it's going to be shown, can be used for display. So, if you have several favicons of different sizes or formats on your site, Yandex services can use any of them.
To display it in search results and advertising campaigns, the robot can download the favicon from the apple-touch-icon tag. If the robot can't access the site during indexing, it might download the hosting favicon from the site's parked page. As a result, search results might show something other than your favicon.
How do I edit or delete a favicon?
To change the favicon in the search results, update the favicon on the site. To delete the favicon from the search, delete the file from the site. Changes will take effect within two weeks after the next robot crawl.
