Hreflang is a tagging system supported by major search engines that specifies the language and country value for a page on your website, as well as their indexable alternates pages targeting other markets.

Hreflang is indeed a tagging system recognized by major search engines like Google to indicate the language and geographical targeting of a webpage. It helps search engines serve the correct language or regional version of a page to users based on their location and language preferences. This is crucial for international SEO as it prevents duplicate content issues and ensures users find the most relevant version of your site. Without hreflang, search engines might struggle to understand which page is most appropriate for a given user, potentially leading to lower rankings or incorrect page versions being displayed.
