What problem does it solve? Incorrect hreflang implementations cause Google to ignore international targeting signals entirely, sending the wrong language version of your pages to users in different countries. This Skill audits existing hreflang setups for critical errors like missing return tags and invalid language codes, and generates correct implementations for HTML, HTTP headers, or XML sitemaps. ## Core Features & Use Cases - Hreflang Validation: Checks self-referencing tags, bidirectional return tags, x-default fallbacks, ISO 639-1 language codes, ISO 3166-1 region codes, canonical URL alignment, and protocol consistency. - Hreflang Generation: Produces ready-to-implement HTML link tags, HTTP header values, or XML sitemap entries with full alternate sets for each page. - Cultural Adaptation & Content Parity Audits: Assesses whether localized pages match cultural expectations (CTAs, trust signals, legal references) and verifies content parity across language versions using word-count ratios and freshness tracking. - Use Case: You run an e-commerce site in English, German, and Japanese. Run the audit to discover your German pages lack return tags and use the invalid code en-uk, then generate a corrected hreflang sitemap ready to deploy. ## Quick Start Ask the assistant to audit the hreflang implementation on your website URL and generate corrected tags for all language versions.
