What Is a Hreflang Tag?
A Hreflang Tag is an HTML or HTTP signal that identifies the language and regional audience for a webpage. Search engines use matching hreflang signals to serve the most suitable version in results. The signal connects equivalent pages, such as Australian English and United Kingdom English versions, without merging their intended audiences.

Key Takeaways About Hreflang Tag
- Hreflang identifies language and regional versions of equivalent pages.
- Each version should point to the relevant alternate versions.
- Hreflang does not translate content or redirect visitors.
How Hreflang Tag Works
Hreflang Tag works by linking equivalent page versions through language and regional codes. A page can identify its Australian English version, United Kingdom English version, or a general English version. Search engines read these signals when selecting a result that fits the searcher's language or location.

Hreflang signals may appear in HTML link elements, HTTP headers, or an XML sitemap. The alternate pages should identify one another, and each URL should remain accessible for crawling. Canonical URL signals still have a separate role, because canonicalisation selects a preferred duplicate while hreflang identifies the suitable regional audience. XML sitemap implementation can help manage the signals across large site structures.
Expert Note
When we work on Enterprise SEO, we map equivalent regional URLs before checking hreflang signals. Our team reviews language-region codes, reciprocal references, canonical URLs, and sitemap entries together. We also test whether each target page matches the audience described by its signal.
Hreflang Tag in Practice: A Real-World Example
An Enterprise SEO site selling equipment across Australia and the United Kingdom may publish separate English pages for each market. Hreflang Tags connect those equivalent pages so search engines can select the regional version that fits the searcher.
