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.

UseRecommendation
PlanningUse your own recent data whenever possible.
ComparisonsKeep the same definition and time period across comparisons.
BenchmarksTreat 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.
