The WPSSO Strip Schema Microdata (WPSSO SSM) add-on removes old Schema Microdata and RDFa markup from the webpage. The settings page also provides for the removal of duplicate / conflicting social and SEO meta tags. WPSSO SSM filters the webpage dynamically, allowing you to activate / deactivate the add-on to easily enable / disable the removal of old Schema Microdata, RDFa, and duplicate meta tags. WPSSO SSM filters are very fast - generally running in under 0.003 seconds!
