WPSSO Strip Schema Microdata


Is Google Search reporting invalid Schema markup from your theme templates?

Do you need to remove old Microdata and RDFa markup from your theme templates?

Do you need to remove duplicate social or SEO meta tags from your webpage?

By default, the WPSSO Strip Schema Microdata (WPSSO SSM) add-on can remove old Schema Microdata and RDFa markup from the webpage. The settings page also allows for the optional removal of duplicate / conflicting Schema markup and meta tags from the webpage head or body sections.

WPSSO SSM filters the webpage dynamically, allowing you to activate or deactivate the add-on to enable or disable the removal of old Schema Microdata, RDFa, and duplicate meta tags. The WPSSO SSM webpage filter is very fast – generally running in under 0.003 seconds.

WPSSO Core Required

WPSSO Strip Schema Microdata (WPSSO SSM) is an add-on for the WPSSO Core plugin, which provides complete structured data for WordPress to present your content at its best for social sites and search results – no matter how URLs are shared, reshared, messaged, posted, embedded, or crawled.


  • WPSSO SSM settings page with options to remove of duplicate / conflicting meta tags, application/ld+json scripts, and/or Schema HTML attributes.

WPSSO gives you the information that you can’t find anywhere else to get your website seen. I was going to switch to a different platform than wordpress but I couldn’t take WPSSO with me so I didn’t. THAT’s how important it is to my business.
