Hreflang tags are crucial for websites targeting multiple languages or regions, telling search engines which version of a page to show to users based on their location and language preferences. However, implementing hreflang incorrectly can lead to various issues impacting your website's visibility and performance. Here are some common hreflang errors and how to fix them:
1. Missing Self-Referencing Hreflang Annotation:
Each page with alternate language versions needs a self-referencing hreflang tag pointing to itself. This clarifies to search engines that the page exists in that specific language and region.
Solution: Ensure every page includes a hreflang tag referencing itself with the appropriate language and region codes (e.g., <link rel="alternate" href="https://example.com/en-us/" hreflang="en-us" />).
2. Return Tag Errors:
Hreflang tags should be reciprocal. If page A links to page B with a specific hreflang tag, page B should link back to page A with the corresponding hreflang tag pointing to page A.
Solution: Double-check that all linked pages have reciprocal hreflang tags pointing to each other with the correct language and region codes.
3. Using the Wrong Country or Language Codes:
Incorrect language or region codes in hreflang tags can confuse search engines and lead to incorrect page display.
Solution: Use the standardized ISO 639-1 codes for languages and ISO 3166-1 codes for regions in your hreflang tags. Avoid using country codes alone without language codes.
4. Not Using Canonical Tags and Hreflang Tags Together Correctly:
Canonical tags specify the preferred version of a page for search engines, while hreflang tags indicate language/region variations. Misusing them can create conflicts.
Solution: Don't include the hreflang attribute within the canonical tag itself. Place the hreflang tags within the <head> section of your HTML separately from the canonical tag.
5. Not Using Absolute URLs:
Hreflang tags should use absolute URLs for linked pages, including the full protocol (http/https) and domain name.
Solution: Ensure all URLs mentioned in your hreflang tags are absolute and resolve correctly when clicked.
6. Missing or Incorrect "x-default" Tag:
For websites with multiple language versions but targeting a primary language/region, use the "x-default" tag to specify the default version if a user's language preference doesn't match any other specified version.
Solution: If you have a primary language/region, include an <link rel="alternate" hreflang="x-default" href="https://example.com/" /> tag in the <head> section of your primary language homepage.
7. Blocked Pages:
Ensure that search engine crawlers can access all pages mentioned in your hreflang tags. Pages blocked by robots.txt or other restrictions won't be indexed properly.
Solution: Verify that all linked pages in your hreflang tags are accessible to search engines and not blocked by robots.txt or other access restrictions.
8. Too Many Alternate Versions:
While hreflang is helpful for targeting multiple languages and regions, having too many variations can create complexity and confuse search engines.
Solution: Only use hreflang for genuine language/region variations and avoid creating unnecessary tags for minor variations.
Additional Tips:
- Use hreflang validators and testing tools to check for errors in your implementation.
- Regularly monitor your website's performance and search engine visibility to identify potential issues related to hreflang implementation.
- Stay updated on the latest hreflang best practices and guidelines to ensure optimal website performance across different languages and regions.
By understanding and addressing these common hreflang errors, you can ensure your website's multilingual content is correctly displayed to users around the world, maximizing your global reach and SEO potential.
