For global brands, creating a multilingual site is a powerful strategy. Hreflang tags communicate to web crawlers that multiple versions of a page exist — each tailored to a specific language or region.
🧩 What Are Hreflang Tags?
🧩 What Are Hreflang Tags?
Hreflang tags are snippets of HTML code that tell search engines which page to serve to which users.
Example:
<link rel="alternate" href="https://example.com/en-us" hreflang="en-us" />
This tells Google to show the U.S. English version.
For Hong Kong English:
<link rel="alternate" href="https://example.com/en-hk" hreflang="en-hk" />
Each version helps Google display the right content to users based on their location and browser language settings.

Rel canonical tells Google which single version of a page to index.
Hreflang, on the other hand, tells Google that all versions should be indexed — each for a different audience.
✅ Each localized page needs its own self-referencing canonical.
If canonicals point to a default or different URL, Google may ignore your hreflang tags.
