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 Doppelte Inhalte , 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.
Die Lösung
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.

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.
Infrastrukturhygiene
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.
