1. Why Hreflang Matters
Hreflang prevents duplicate content across languages and regions. It helps Google serve the correct version to users based on their location and language preference, improving user experience and rankings.
2. How NakedURL Checks Hreflang
We scan for link elements with rel="alternate" and hreflang attributes. We count them and flag missing x‑default and invalid language codes. We also check if the page has a self‑referencing hreflang (recommended).
3. Best Practices for Hreflang
Use full ISO language codes (e.g., "en-GB", "es-ES"). Include a self‑referencing hreflang for each page. Add an x‑default for users without a matching language. Validate your implementation with NakedURL.
- Use complete language‑region codes
- Add self‑referencing hreflang for each page
- Include x‑default as fallback
- Validate with Google Search Console
⚠️ The Problem
Hreflang errors confuse search engines
- Missing hreflang – wrong version served
- Invalid language codes – ignored by Google
- No self‑referencing – ambiguous
- No x‑default – users without match get wrong content
✅ NakedURL Solution
NakedURL gives you a hreflang health check
- Count hreflang tags on the page
- Check for self‑referencing hreflang
- Validate language codes against ISO standards
- Recommend adding x‑default and missing tags
Key Features
Hreflang count
See how many hreflang entries exist.

Check if the page has a hreflang pointing to itself.

x‑default
Check if an x‑default is defined.
I have hreflang tags, but NakedURL says no self‑referencing. Why does that matter?
Self‑referencing hreflang tells Google that this page is the canonical for that language. Without it, Google may treat the page as not explicitly targeted. Add hreflang with the same URL to avoid confusion.
