# Hreflang Tag Generator

Generate correct hreflang tags for multilingual and multi-region websites. Output as HTML link tags, HTTP headers, or XML sitemap format. Validates self-referencing, reciprocal links, and x-default usage.

## Hreflang Best Practices

- Every page must include a hreflang tag that references itself (self-referencing is required by the specification).
- Hreflang annotations must be reciprocal: if page A references page B, page B must reference page A.
- Always include an x-default tag pointing to your main language or a language selector page.
- Use the full language-region format (en-US, en-GB) when you have country-specific content, not just the language code.
- Choose one implementation method (HTML tags, HTTP headers, or XML sitemap) and use it consistently across your site.

## Frequently Asked Questions

### What is the difference between hreflang language and region codes?

The language code (e.g., en, es, fr) follows ISO 639-1 and identifies the language. The region code (e.g., US, GB, MX) follows ISO 3166-1 and identifies the country. Use language only (en) when content is not region-specific, and language-region (en-US, en-GB) when you have country-specific variations.

### What is x-default and when should I use it?

x-default is a special hreflang value that tells search engines which page to show when no other language variant matches the user. Point it to your main language version or a language selector page. Google recommends always including an x-default annotation. When you tick x-default on a variant, this tool adds the x-default line next to that page's own language tag, so the page still references itself.

### Should I use HTML tags, HTTP headers, or XML sitemap format?

Use HTML link tags for standard web pages since they are easiest to implement and debug. Use HTTP headers for non-HTML files like PDFs. Use XML sitemap format for large sites with many language variants where adding tags to every page is impractical.

### Do hreflang tags affect rankings?

Hreflang tags do not directly boost rankings, but they prevent search engines from treating your translated pages as duplicate content. They also ensure the right version appears in each country's search results, which improves click-through rates and reduces bounce rates from language mismatches.

### How do I verify my hreflang implementation is correct?

Use this tool's built-in validation to check for common errors. After deploying, use Google Search Console's International Targeting report to see if Google detects any hreflang errors. Third-party tools like Ahrefs Site Audit also flag hreflang issues during crawls.
