In plain English
Hreflang helps Google serve the appropriate localized URL. It does not translate content, target Bing, replace canonicals or guarantee a particular result.
01
Why does Hreflang matter?
International sites can otherwise show the wrong country or language page.
Broken return links, invalid codes and non-canonical destinations can invalidate an entire cluster.
02
How does Hreflang work?
- Create a cluster
Every equivalent page lists itself and all alternates using supported language-region codes.
- Return annotations
Each alternate must link back to the others.
- Use x-default
Optionally specify a fallback selector or default page.
- Serve localized content
Language, currency, offers and internal links should genuinely fit the market.
03
A practical Hreflang example
Scenario
A service has English-India and English-Philippines versions with distinct offers.
Interpretation
Each canonical 200 page can reference en-IN and en-PH alternates plus x-default, with reciprocal annotations.
04
Common mistakes and misconceptions
- Using country without language
Hreflang begins with a supported language code; country is optional.
- Pointing to redirects
Annotations should resolve to canonical indexable URLs.
- Replacing localization with tags
Annotations cannot make translated boilerplate useful to a market.
