HREF Lang

HREF Lang is a system for indicating to search engines that on page is available in different language translations. Links to each translation of a page are included in the <head> tag of the page or in XML sitemaps, with this special tagging, so that Google can share the SEO value of the pages, and rank different translations of a page based on the specific language of the users. Each translation must be linked with a separate tag, and ideally, a default language should be set for the site in the HREF Lang tagging.
