Do I need to duplicate seo texts on the mobile version?

Question

Search Engine Optimization

There is a full version of the site doctu.ru and a mobile version on the m.doctu.ru subdomain. Do I need to duplicate seo texts from the full version on the pages of the mobile version? Is it good, bad, or does it matter how it's done?

Answer 1

it is enough to write rel="alternate" to indicate the mobile address and vice versa
