Hreflang tags are HTML tags used to tell search engines what language and region a specific page is targeting. They are especially important for multilingual or international sites.

Here’s why they’re essential for technical SEO:

• Language targeting : hreflang tags help search engines understand what language a given page is written in. This helps the engines display the appropriate version of the page to users based on their preferred language.
  
  
• Geographic targeting : In addition to language, hreflang tags can also indicate the region or country a specific page is intended for. This is crucial for sites that offer specific versions tailored to different geographic markets.
  
  
• Avoid duplicate content : When there are multiple language or regional versions of a page, hreflang tags help avoid duplicate content issues. They inform search engines about the relationship between different versions of the same page, helping to assign the appropriate content to search results.
  
  
• Improve the relevance of search results : By using hreflang tags correctly, you improve the relevance of search results for users in different regions and languages, which can increase visibility and traffic from those target audiences.
