Free Hreflang Checker: Validate International SEO Tags & Language Targeting

Validate your global routing logic and prevent duplicate content penalties—at no cost.

In International SEO, hreflang tags are the GPS coordinates of your infrastructure. They tell Google, "This page is for users in France, and this identical page is for users in Canada." Without them, search engines view your localized pages as Duplicate Content, destroying your rankings.

The MultiLipi Hreflang Checker is a free engineering utility that audits your cross-border signals. It verifies that your language codes are valid, your return tags are reciprocal, and your global architecture is correctly mapped for search bots.

The Routing Protocol

Why Hreflang is critical for GEO.

Search engines and AI models prioritize User Experience. If a user in Mexico searches for your brand, they must land on your /es-mx/ page, not your /es-es/ (Spain) page.

The Risk

Without valid hreflang tags, Google might index only one version of your site and hide the rest, assuming they are duplicates.

The Fix

Our tool ensures that every page points to its alternate versions, creating a "Cluster" of authority that tells algorithms exactly which page to serve in which region.

The Audit Protocol

How to validate your signals.

Hreflang errors are invisible to humans but fatal to bots. Run a scan to ensure your map is accurate.

1

Access the Free Tool

Navigate to the Hreflang Tag Checker.

2

Input Target

Enter the specific URL you want to test (e.g., yoursite.com/pricing).

3

Execute Scan

Click the Analyse Website button.

4

Review Intelligence

The tool provides a matrix of your routing logic.

Report Intelligence:

Detected Tags: Lists all rel="alternate" tags found in the source code

ISO Validation: Checks if you used valid language/region codes (e.g., flagging en-UK as an error because the correct code is en-GB)

Return Tag Check: Verifies that page A points to page B, and page B points back to page A (the "Return Signal")

Common Vulnerabilities Detected

What kills international rankings?

Our engine specifically hunts for the most common deployment errors:

Missing Self-Referencing Tag

Every page must point to itself as well as its alternates.

Broken "X-Default"

Verifies you have a fallback page defined for users who don't match any specific language.

Non-Canonical Errors

Ensures hreflang tags are only pointing to the canonical versions of your pages, not redirect chains.

Infrastructure Hygiene

Automated auditing.

If you use MultiLipi to translate your site, we inject these tags automatically. However, if you are managing a custom stack or migrating legacy pages, use this tool to verify your Source-to-Target mapping.
