Why Hreflang Tags Matter

Hreflang attributes are link tags placed in the HTML <head> block of web pages. They tell Google and other search engines about localized translations of your content.

This ensures search engines serve the correct language version to users based on their search settings and geographic location, preventing duplicate content issues across localized domains.

Step-by-Step Guide: How to Use this Tool

  1. Enter the canonical URL of your primary page (e.g. https://www.mysite.com) and its language code (en).
  2. Add alternate translation URLs and language codes (e.g. es for Spain, fr for France).
  3. The tool generates HTML tags, including the x-default fallback tag.
  4. Copy the output and paste it into the header block of your pages.

Best Practices for Hreflang Setup

  • Reciprocal Links: If page A links to page B using an alternate hreflang tag, page B must also link back to page A. Missing reciprocal links will invalidate the setup.
  • Use Valid ISO Codes: Always use ISO 639-1 format for languages and ISO 3166-1 Alpha-2 format for regions (e.g. en-us).
