What are hreflang tags?

Hreflang tags are HTML attributes that tell search engines which language and regional version of a page to show to users. They prevent duplicate content issues across multilingual sites.

When do I need hreflang tags?

You need hreflang tags if your website has content in multiple languages or targets different regions with the same language (e.g., English for the US vs. UK). They ensure users see the correct version in search results.
