Story Based Question
You’re working on an international SEO project for an e-commerce website that serves multiple countries with country-specific domains. You’ve implemented hreflang tags to ensure that the right content appears for the right audience in different regions. However, after a thorough audit, you notice that there are duplicate hreflang implementations across several pages, causing confusion and affecting your SEO performance. You wonder, How do I resolve issues with duplicate hreflang implementations to ensure proper indexing and ranking in each market?
Exact Answer
To resolve issues with duplicate hreflang implementations, remove conflicting hreflang tags, ensure each page has only one set of hreflang tags, validate hreflang across your site, and fix any technical issues like incorrect self-referencing or missing return tags.
Explanation
Duplicate hreflang tags can cause search engines to misinterpret which page version to show in a specific region. This can negatively impact your rankings and lead to a poor user experience. Here’s how to identify and resolve issues with duplicate hreflang tags:
- Remove Conflicting or Duplicate Tags
- Duplicate hreflang tags occur when the same page contains multiple conflicting hreflang attributes. This happens when you have two or more sets of hreflang tags pointing to the same URL or different URLs for the same target market.
- Solution: Ensure each page has only one, consistent set of hreflang tags. Review the implementation and remove any redundant or conflicting tags that point to the same target region.
- Fix Incorrect Self-Referencing Tags
- A common mistake is adding a self-referencing hreflang tag that points to the same page with the same language and country code. While this is technically correct, search engines may treat this as a duplicate signal.
- Solution: While self-referencing hreflang tags are allowed, avoid overusing them. Check if your self-referencing hreflang tags are necessary and properly implemented, particularly in the header or XML sitemap.
- Validate Hreflang Tags Using Tools
- Tools like Google Search Console, Screaming Frog, or hreflang validators can help you find duplicate or conflicting hreflang implementations across your site.
- Solution: Use these tools to crawl your site and identify any duplicate hreflang tags. Once identified, fix the conflicting implementations to ensure that the correct hreflang attributes are assigned.
- Ensure Proper Return Tags
- Hreflang tags need to be reciprocal, meaning each language or region-specific page should link back to the others. If the return tag is missing, it can cause indexing issues and confuse search engines.
- Solution: For each hreflang tag, ensure there is a corresponding return tag. For example, if page A targets the U.S. (en-US), then page B targeting the UK (en-GB) should also link back to page A with an appropriate hreflang tag for the U.S.
- Check for Correct URL Format
- The URL specified in the hreflang tag must be correct. Incorrect URLs can cause search engines to ignore the hreflang implementation.
- Solution: Double-check that the URLs in your hreflang tags are fully qualified (including “https://”) and point to the correct page.
- Audit Your XML Sitemap for Hreflang Tags
- If you’re using XML sitemaps to implement hreflang, ensure that the sitemap is up to date and doesn’t contain duplicate or conflicting hreflang entries.
- Solution: Review the XML sitemap for any duplicate hreflang tags and ensure each page is listed with the correct language and region. You may need to regenerate the sitemap or adjust it to fix any conflicts.
Example
Imagine you’re managing an e-commerce website with country-specific domains for the U.S. (.com), UK (.co.uk), and Germany (.de). After running an audit, you find the following issues with your hreflang implementation:
- Duplicate Tags:
- On the product page for a pair of shoes, you notice that there are two sets of hreflang tags pointing to the same U.S. version of the page (en-US).
- Solution: You remove the extra set of conflicting hreflang tags to ensure only one set points to en-US for that page.
- Self-Referencing Tags:
- On the German page (de-DE), you have a self-referencing hreflang tag (de-DE). While this is valid, it’s unnecessary since the page should only be referenced in the German market.
- Solution: You leave the self-referencing tag, but ensure that it does not conflict with any other hreflang tags pointing to the same content.
- Missing Return Tags:
- You notice that the UK page (en-GB) doesn’t link back to the U.S. page (en-US), causing a mismatch in the hreflang implementation.
- Solution: You add the return hreflang tag on the UK page that links back to the U.S. page, ensuring a reciprocal relationship between both pages.
- Incorrect URL Format:
- On the French version of your site, the hreflang tag points to “www.example.com/fr” instead of “https://www.example.com/fr“.
- Solution: You correct the URL format to “https://www.example.com/fr” to make sure that search engines correctly index the French page.
- XML Sitemap Issue:
- Your XML sitemap includes duplicate hreflang tags for the German page, with some tags pointing to the German version and others mistakenly pointing to the U.S. version.
- Solution: You regenerate the XML sitemap, ensuring that each page includes only the correct hreflang attributes for its target market.
Resolving duplicate hreflang issues is essential for ensuring that search engines understand which version of your content to show to users in different regions. By removing conflicting tags, ensuring proper return tags, validating hreflang with SEO tools, and checking your sitemap, you can fix duplicate implementations and improve your international SEO strategy.
