The Hreflang tag is an attribute that helps show that additional URLs are linked to a web page in other languages or in specific regions. It is ordinarily placed in a link element in the HTML head of a web page.
Websites use hreflang attributes to draw attention to the fact that translated pages are not plagiarised but are instead related to the original content. Not only does this help websites avoid search engine demotion for duplicating pages, but it also helps those search engines provide results in the correct language for users from different countries.
If you have multiple versions of your web pages for different languages and regions, you can use our free Hreflang Tags tool to check that your HTML and HTTP headers are correct.
