If you manage a multilingual WordPress website, you’ve likely encountered the infamous “hreflang errors” warning. A single mistake in these signals can cause Google to show your French content to German users and your Spanish website to English-speaking visitors, frustrating your international SEO efforts.
This guide will walk you through everything from the basics of hreflang up to advanced troubleshooting using the primary keyword “hreflang errors fix wordpress” as our guiding principle. By the end, you will have a complete checklist to audit, fix, and validate your implementation.
What Are Hreflang Tags in WordPress?
Before you start a “hreflang errors fix wordpress” audit, it is crucial to understand what these tags are and how Google uses them.
What Hreflang Tags Actually Do
The hreflang attribute is an HTML tag placed in the <head> section of your webpage. Its structure looks like this:
<link rel="alternate" hreflang="es-ES" href="https://tusitio.com/es/pagina-ejemplo/" />
This tag tells search engines: “This content is an alternative version. It is written in Spanish (es) for users in Spain (ES).”
Difference Between Language and Country Targeting for an Effective Hreflang Errors Fix WordPress
A typical “hreflang errors fix wordpress” scenario often involves confusing language with country targeting. They are not the same thing.
- Language targeting (
hreflang="en"): You are targeting all English speakers globally, regardless of where they live (US, UK, Australia, Canada). Use this when the content is interchangeable for all English-speaking users (e.g., a global blog). - Country/Language targeting (
hreflang="en-US"orhreflang="en-GB"): Use this when the content is specific to a region—different prices, currencies, or shipping options. Google uses signals like IP address to determine which localized version to serve. Notably, a multilingual WordPress plugin uses language codes like ‘en’ and ‘fr’ to target speakers respectively, with regional variations for specific countries.
How Google Uses Hreflang Annotations
Google’s John Mueller has clarified that hreflang is a signal, not a directive. This means Google takes your hreflang tags as strong suggestions but does not blindly obey them.
If Google crawls your tags and finds contradictions (e.g., Country A pointing to Page B, but Page B does not point back to Country A), it may ignore the annotation entirely. Google uses these tags to swap pages in search results for the correct geographic location. According to Google Search Central, a Spanish user searching in Spain should see the es-ES version, not the global English page.
Why Hreflang Matters for International SEO
The reason international SEO relies on these tags is simple: user intent. A native speaker is far more likely to convert if the landing page is in their language. Without proper tags, you lose traffic to competitors who correctly serve localized versions.
Why Hreflang Errors Hurt Your SEO
Ignoring a “hreflang errors fix wordpress” checklist doesn’t just cause minor warnings; it actively damages your search performance.
Duplicate Content Issues & Lost International Rankings
If you have domain.com/en/ and domain.com/es/, without hreflang, Google may think these are duplicate pages competing against each other. Instead of ranking well in both regions, Google might penalize one version or rank them incorrectly, sending all your authority to a single domain.
Incorrect Language Versions in Google
This is the most visible error. A user in Paris searching for your brand sees the English text snippet in the SERPs, which destroys your click-through rate (CTR) and damages your brand trust. It can also cause indexing conflicts where important pages are ignored.
Indexing and Canonical Conflicts
If the canonical tag of a German page points to an English URL, Google will prioritize the canonical. If the hreflang points to the German page but the canonical points to English, Google becomes confused and the “hreflang errors fix wordpress” process becomes meaningless.
The Most Common Hreflang Errors in WordPress
Hreflang errors in WordPress are extremely common, especially when using automated translation plugins. Let’s review the most frequent issues:
- Missing Return Tags: The reciprocal links are missing, meaning Page A links to Page B, but Page B does not link back. When a translated archive is not properly connected, it causes missing reciprocal links.
- Missing Self-Referencing Hreflang: Each page must include a tag pointing to itself (e.g., the Spanish page must have an
hreflang="es"pointing to its own URL). - Invalid Language or Country Codes: Mixing up
en-UK(incorrect) vsen-GB(correct). Usingen-eu(invalid) instead of standard codes. - Hreflang Pointing to Redirects (301): Tags referencing a URL that returns a 301 status code to another destination. Google follows the redirect and may ignore the hreflang signal.
- Canonical and Hreflang Conflicts: For example, hreflang points to
page.com/de/but the canonical on that page points topage.com. - Incorrect x-default Implementation: The
x-defaulttag should point to your language selector page or a neutral landing page, not a specific language homepage. - Non-Indexable Pages: Hreflang pointing to pages blocked by
noindex. - Mixed HTTP and HTTPS URLs: Having both secure and non-secure versions in your tags.
How to Identify Hreflang Errors
A thorough “hreflang errors fix wordpress” strategy must start with proper detection.
Using Google Search Console
Navigate to your property, go to “International Targeting” under “Experience” or “Legacy” reports, and select the “Country” tab. Google lists exactly which pages have missing return tags, wrong codes, or broken links.
Using Ahrefs Site Audit & Semrush Site Audit
If you have paid tools like Ahrefs or Semrush, run a full site crawl and filter by “Hreflang Issues.” Ahrefs is specific about what causes errors, such as Missing return tags, No return tags, or `Invalid hreflang annotation. Semrush offers a similar detailed breakdown.
Using Dedicated Hreflang Testing Tools
Free tools like Merkle’s Hreflang Tester or HreflangBuilder.com allow you to paste a URL and validate all tags on the page. If you prefer a lightweight manual check, right-click your page, “View Page Source,” and Ctrl+F search for hreflang.
How to Fix Missing Return Tags
The cardinal rule of hreflang is reciprocity.
What Reciprocal Hreflang Means
If you have three language versions (English, German, French), each of those three pages must list all three URLs in their tags. English URL must link to DE and FR, DE must link to EN and FR, and FR must link to EN and DE.
How to Fix Return Tags in WordPress
With plugins like WPML, Polylang, or TranslatePress, you usually do not hardcode these tags. To fix return tags in these plugins:
- Polylang: Go to the “Languages” settings and ensure your content is linked correctly.
- TranslatePress: Use its custom language settings; if they are missing, you may need a filter to modify the tags.
- Yoast SEO + WPML: The primary fix is to check language connections in WPML. Ensure each post/page is assigned to its counterpart in the translation editor, which forces the reciprocal tags to appear.
How to Fix Invalid Hreflang Codes
Using the wrong codes is a common error that can stall your international rankings. Standard codes differ from what your WordPress locale might suggest.
- Correct ISO Language Codes (ISO 639-1): Always use two-letter lowercase codes (
en,fr,es,de). Never use full names or three-letter codes likeeng. - Correct Country Codes (ISO 3166-1 Alpha-2): Use two-letter uppercase country codes (
US,GB,ES). - Common Mistakes:
en-UKis invalid. The correct code isen-GB.es-419(Latin America’s language tag) is not supported by Google’s hreflang parsing system.
How to Fix Hreflang and Canonical Conflicts
A major conflict arises when your canonical tag tells Google one thing and your hreflang tells another.
Why Canonical Conflicts Happen
For example, if your English page domain.com/en/page/ has a canonical pointing to domain.com/page/, but the hreflang on that page points to domain.com/es/page/, Google will likely ignore the hreflang signal and follow the canonical. This can be extremely frustrating when trying to perform an effective “hreflang errors fix wordpress” on a site with a messy theme.
Fixing Canonical Issues
- In Rank Math: The plugin automatically includes self-referencing canonical tags (pointing to the current URL) when your page is indexable. However, ensure you do not manually overwrite the canonical in the meta box to a different URL.
- In Yoast SEO: The multilingual plugin controls the canonical relationship. In Yoast SEO, you can set a primary translated page. This is often managed by WPML’s language settings.
How to Fix Hreflang Redirect Errors
Hreflang should always point to the final destination URL (HTTP status 200).
Why Redirected URLs Break Hreflang
Imagine you migrated your site from HTTP to HTTPS. If your tags still point to http://... but 301 redirect to https://..., Google will report a redirect error and may discard the hreflang value.
Update your sitemap and hardcoded tags to reflect the current HTTPS URL and ensure your language structure includes or excludes trailing slashes consistently.
How to Fix Hreflang Errors in Popular WordPress Plugins
Since most users rely on plugins, the “hreflang errors fix wordpress” process varies depending on your tech stack.
Fixing Hreflang Issues in WPML
WPML is the most popular multilingual WordPress plugin. If hreflang errors appear in Yoast SEO with WPML, ensure you have updated plugins.
WPML SEO version 2.2.2 changed how tags are output. As part of the fixing process, you may, in specific cases, need to add a snippet to your functions.php to force tags back into the <head> or adjust region codes. If you see only fr instead of fr-FR, go to WPML → Languages → Edit Languages and verify the “hreflang” field.
Fixing Hreflang Issues in Polylang
Polylang is highly automated and W3C compliant, converting underscores to dashes (en_ZA to en-ZA). However, it lacks built-in tools for the x-default tag. You might need a custom filter to add an x-default entry to all pages.
Fixing Hreflang Issues in TranslatePress
TranslatePress automatically generates tags based on subdirectories by default, keeping all authority on one domain. However, a known issue with TranslatePress is that it may duplicate tags or add them to non-indexable pages. You can set up manual exclusions.
Fixing Hreflang Issues in Rank Math
Rank Math does not generate the tags — it relies on your translation plugin. If the tags are missing in your sitemap, check if your translation plugin is handling them correctly. If you notice duplicate tags, disable Rank Math’s automatic schema language detection to avoid conflicts.
How to Validate Your Hreflang Implementation
Running a Technical SEO Crawl & Verifying Reciprocal Links
Use tools like Screaming Frog or Sitebulb to crawl all language versions. Screaming Frog can crawl both directories and verify that Page A links to Page B and Page B links back to Page A.
Checking Source Code & Google Search Console
After implementing your fixes, revisit Google Search Console. Request re-crawling of your URLs via the URL inspection tool. It may take a few days, but the “International Targeting” report should eventually show “No errors” for your tags.
Best Practices for Hreflang in WordPress
- Always Use Self-Referencing Hreflang: Every page must list itself in its hreflang cluster.
- Keep All Language Versions Consistent: If your English page links to German and French, those German and French pages must link back to each other and to English.
- Use x-default Correctly: Point
x-defaultto a neutral page (like a language picker), not a specific country page. - Avoid Auto-Generated Translation URLs: Do not generate hreflangs for machine-translated placeholder content. Only mark pages as ready when they have distinct, human-reviewed content.
- Keep XML Sitemaps Updated: Any changes in your URL structure should immediately refresh your sitemap.
Final Checklist to Fix Hreflang Errors in WordPress
- Audit all multilingual URLs using Google Search Console.
- Check status codes of every hreflang target.
- Verify Return Tags for every language pair.
- Validate language codes against ISO standards.
- Resubmit pages in Google Search Console after fixes.
Conclusion: Mastering the “hreflang errors fix wordpress” process is essential for any site owner serious about global traffic. By understanding the errors and applying the specific plugin-based fixes outlined above, you ensure that Google serves the correct pages to the correct countries
Hreflang works best when canonical tags, language versions and return links all agree. Small template mistakes can create confusing international SEO signals.
