Micromarking of organization contacts on each page?

Question

Search Engine Optimization

Question about the micro-layout of contacts. Contacts are in the footer of the site on each page. Should I implement semantic markup in the footer? Or do it only in the contacts section on the site itself?

Answer 1

Yes, if there are contacts in the footer, then we wrap them with Schema Organization or hCard

Answer 2

From my practice.
1. The presence on the page of a link with the anchor "Contacts" does not affect the position of the page in the Yandex search results and negatively affects the position in Google.
2. The presence of a link on the page with href="/contacts*" is a little good for Yandex, bad for Google.
Don't ask me why, I don't know, the data comes from observing the positions of 1.2 million pages during the year.
The presence of micro-markup for organizations was not checked, set it as a task.
