Mobile-Friendly Test (Bulk Testing Tool)
Use this bulk validator to check if one or more URLs (up to 100) are valid Accelerated Mobile Pages (AMP). If a submitted URL is not AMP, the tool will look for an AMP URL linked to via the rel="amphtml" tag and test it. This testing tool is using the official AMP Project validator but also checks the implementation of your AMP URLs: does the referenced canonical URL point back to the AMP with a rel="amphtml" tag?
