hreflang is the acronym for Hypertext Reference Language.

Hypertext Reference Language
An HTML attribute is used in the head section of a webpage or in an XML sitemap to indicate a specific page’s language and regional targeting. Hreflang tags help search engines understand the relationship between different language versions of a webpage, ensuring that users see the appropriate language version in search results based on their language preferences and location.
Example:
<link rel="alternate" hreflang="fr" href="https://fr.martech.zone/"/>
