What Is Hreflang and Why It Matters
The hreflang attribute tells search engines which language and regional version of a page to show users in different locations. Get it wrong, and you risk showing the wrong language to visitors, splitting your SEO authority across duplicate pages, or triggering indexing issues across international markets.

Frequently Asked Questions
Do I need hreflang if my site only has one language?
No — hreflang is only relevant when you have multiple language or regional versions of the same content.
Can incorrect hreflang tags hurt my rankings?
They can cause search engines to show the wrong page version to users or dilute ranking signals across duplicate-looking pages — both of which hurt visibility and user experience.
Where do hreflang tags go?
In the head of your HTML, in HTTP headers, or in your XML sitemap — our validator checks the most common implementation in your page's HTML.
