HomeSeo BlogInternational SEO Tips

Expanding your website to international markets is exciting, but ensuring the right audience sees the correct language version is crucial. This is wherehreflang tagscome in – they help search engines deliver the right content to users based on their language and location.

In this guide, we’ll break down what hreflang tags are, why they matter, and how to implement them to boost your international SEO efforts.

What Are Hreflang Tags?

Hreflang tags are HTML attributes that tell search engines which language and regional version of a page to display to users. They are essential for:

  • Directing users to the right language version of your website.
  • Avoiding duplicate content issues across different language pages.
  • Improving user experience by ensuring visitors land on the most relevant page.

Pro Tip: Hreflang tags are especially useful for multilingual websites, e-commerce platforms, and global businesses targeting audiences in multiple countries.


Why Are Hreflang Tags Important for SEO?

Without hreflang tags, search engines might display the wrong language version of your page to users, which can result in:

  • High bounce rates – Users leave if the content isn’t in their language.
  • Indexation issues – Duplicate content without proper signals can confuse search engines.
  • Lost traffic and conversions – If users can’t read your content, they won’t engage or buy.

Pro Tip: Implementing hreflang correctly improves search rankings in specific countries by signaling to search engines which page variant to prioritize.


How to Implement Hreflang Tags (Step-by-Step)

1. Choose the Right Placement:

  • HTML Section:



  • XML Sitemap:

  https://example.com/us
  
  


  • HTTP Header (for non-HTML content):
Link: ; rel="alternate"; hreflang="en-us"

Pro Tip: Use XML sitemaps if managing a large site to avoid bloating your HTML.

Use Correct Language and Region Codes:

  • Language Code: Follows ISO 639-1 standards (e.g., en for English, fr for French).
  • Country Code: Follows ISO 3166-1 Alpha 2 standards (e.g., us for United States, fr for France).
  • Combine codes: en-us (English for the US), fr-fr (French for France).

Add Self-Referencing Hreflang Tags:

Every page should include an hreflang tag for itself.

Testing and Validating Hreflang Tags

Testing ensures your hreflang setup works as expected. Use the following tools:

  • Google Search Console – Check for hreflang errors in the International Targeting report.
  • Ahrefs or SEMrush – Conduct SEO audits for hreflang implementation.
  • Screaming Frog – Crawl your site to detect hreflang tags and fix errors.

Pro Tip: Regularly audit hreflang tags, especially when adding new pages or languages.


Common Hreflang Mistakes to Avoid

  • Incorrect Language/Region Codes – Ensure all codes are ISO-compliant.
  • Missing Self-Referencing Tags – Always include a self-referencing hreflang.
  • Broken URLs – Make sure all hreflang URLs are live and accessible.
  • Mismatch Between Versions – Double-check that all language versions cross-reference each other.

Structuring Multilingual Sites

  • Country Code Top-Level Domains (ccTLDs): example.de (Germany), example.fr (France)
  • Subdirectories: example.com/de/
  • Subdomains: de.example.com

Pro Tip: Subdirectories are preferred for SEO as they inherit domain authority, while ccTLDs boost local trust.


Hreflang tags are a powerful yet often overlooked element of international SEO. By guiding search engines to display the correct version of your site, you improve user experience, reduce bounce rates, and enhance your global reach.
