Inspect hreflang annotations on a webpage
Find hreflang link annotations, language-region codes, x-default and duplicate entries on a public webpage.
Inspects hreflang annotations on one page. It does not crawl every alternate page for reciprocal validation.
How to use the Hreflang Checker
Find hreflang link annotations, language-region codes, x-default and duplicate entries on a public webpage.
Formula and method
The checker reads HTML link elements with rel=alternate and hreflang attributes and lists the annotations found on the tested page.
Example
A multilingual page may include en, fr, ar and x-default annotations pointing to equivalent localized URLs.
Planning examples
These examples are mathematical scenarios designed to help with planning. They are not claims about typical market performance.
| Use | Recommendation |
|---|---|
| Planning | Use your own recent data whenever possible. |
| Comparisons | Keep the same definition and time period across comparisons. |
| Benchmarks | Treat public benchmarks as context rather than guarantees. |
How to interpret the result
This fast check inspects one page only. A complete hreflang audit should also confirm reciprocal annotations and canonical consistency across localized pages.
