Are your hreflang tags correct?
Generate and validate hreflang tags for international SEO. Check for missing return tags, invalid language codes, and inconsistencies.
What are Hreflang Tags?
Hreflang tags are HTML attributes that tell search engines about the language and geographic targeting of a page. They help search engines serve the right version of your content to users based on their language and location — showing the French version to users in France and the Spanish version to users in Spain.
Hreflang implementation is notoriously error-prone. Every page must reference all its alternate versions, every reference needs a matching return tag, language codes must follow ISO 639-1, and region codes must follow ISO 3166-1 Alpha 2. A single missing return tag or invalid code can break the entire implementation.
Hreflang Generator creates correctly formatted tags for your pages and validates existing implementations — checking for missing return tags, invalid codes, and inconsistencies that could hurt your international SEO.
