What Is a Hreflang Tag?
A Hreflang Tag is an international SEO signal that identifies the language and regional audience for an alternate version of a webpage. Search engines use these annotations to understand relationships between equivalent pages, such as English content for Australia and French content for France. Hreflang Tags help direct searchers towards the most suitable version.

Key Takeaways About Hreflang Tag
- Hreflang identifies language and regional targeting.
- Each alternate page needs a matching, valid reference.
- Hreflang does not replace canonical tags.
How Hreflang Tag Works

A Hreflang Tag tells search engines which language and regional audience a page serves. Website owners can provide the annotation in HTML, HTTP headers, or XML sitemaps. Each language or regional version points to the relevant alternate URL, and pages generally reference the available versions as a connected set.

Canonical Tags address the preferred URL among duplicate or near-duplicate pages. Hreflang addresses audience targeting, so both signals may appear on the same page. A regional code can identify a market, while a language code identifies the content language. Search engines assess these signals alongside page content and other technical information when selecting a result for a searcher.

Expert Note
When we review Hreflang Tags, we check the language and regional values, destination URLs, and reciprocal references. We also compare the annotations with canonical signals, indexable page versions, and sitemap entries. Our team checks whether changes remain consistent across templates and regional sections.
Hreflang Tag in Practice: A Real-World Example
A Geelong retailer with Australian English and New Zealand English product pages can use Hreflang Tags to connect the regional versions. The Australian page can identify en-AU, while the New Zealand page identifies en-NZ and references the corresponding alternate URL.
