Hreflang Tag Generator

Seo REST API MCP

Generate hreflang annotations for multilingual pages and return them as HTML <link> tags, an HTTP Link header, and an XML sitemap block, plus validation issues (invalid URL, language, or region code, duplicate language-region pairs, missing x-default). Pass one page group as variants, or several as groups.
