Are your hreflang tags correct?
Generate and validate hreflang tags for international SEO. Check for missing return tags, invalid language codes, and inconsistencies.
Hreflang tags tell search engines which language and regional version of a page to show to users. Getting them wrong means search engines might show the wrong language to your visitors, or treat your international pages as duplicate content. Hreflang Generator helps you create correct tags and validates existing implementations.
Hreflang Tag Validation
Hreflang implementation is notoriously error-prone. Every page must reference all its alternate versions, every reference needs a matching return tag, and all codes must follow ISO standards. Hreflang Generator creates correctly formatted tags and validates existing implementations for missing return tags, invalid codes, and cross-page inconsistencies.
What we check:
- Tag generation for all language variants
- Return tag verification
- ISO language and region code validation
- Cross-page consistency checks
