HREFLang Element testing tool allows you to test your HREFLang Elements for both a specific page as well as for an HREFLang XML Site Map.
In Page Testing - we only check those pages referenced in the page entered and not your entire site. Test each URL separately.
XML Site Map Testing - This tool will can only test blended HREFLang XML Site maps. If you have individual XML files for each country version this tool CANNOT test them. There are some XML Site Map tests that can be done with HREFLang Builder.
