Hreflang Tag Generator
hreflang tags tell Google which URL serves which language and country. Critical for sites with multiple language versions or country-specific content. This generator builds tags with validation for missing x-default and duplicate language codes.
hreflang tags tell Google that a URL has alternate language or country versions. Without hreflang, Google may serve the wrong language to a user (e.g. show the German page to a French user who landed on it accidentally). For multi-country B2B SaaS sites, hreflang is essential.
Three options: (1) in the as , (2) in the XML sitemap as elements, (3) in the HTTP header (for non-HTML files). Most sites use head tags. The set must be implemented on every language version with reciprocal tags.
x-default is the fallback language used when none of the explicit hreflang values match the user's language. Typically points to the default English version. Strongly recommended for multilingual sites.
Use ISO 639-1 (two-letter) codes for language only: en, de, fr, ru. Add ISO 3166-1 Alpha-2 region codes for language-region specificity: en-US, en-GB, de-CH (Swiss German), fr-CA (Canadian French). Mismatched or invalid codes cause GSC errors.
