The NextGEN Facebook (NGFB) and WordPress Social Sharing Optimization (WPSSO) plugins offer a “Meta Property Containers” option that you can enable / disable under their General Settings > Specific Websites and Publishers > Google / Schema tab. There are several ways to include Schema markup in webpages (see an Introduction to Structured Data from Google for examples):

  • JSON-LD machine-readable scripts for Google (see WPSSO JSON extension).
  • Microdata and RDFa markup of HTML tag attributes in theme templates (not recommended).
  • HTML meta tags in the webpage head section.

wpsso-json-icon-round-2048x2048

WPSSO Schema JSON-LD Markup (WPSSO JSON) version 1.11.1-1 has been released and features improved markup for the Schema item types Blog, CollectionPage, ProfilePage, and SearchResultsPage. Each of these “archive” page Schema types now include a “hasPart” property to list posts in the current view (WordPress blog home page, date / category / tag archive pages etc, and search results).

NGFB version 8.37.2-1 and WPSSO version 3.37.2-1 have also been released. The “Item Type for Home Page” option has been replaced by two new options — “Item Type for Blog Home Page” and “Item Type for Static Home Page” — allowing you to select different Schema types for each. The WordPress blog home page defaults to https://schema.org/Blog, with posts listed in the JSON-LD “hasPart” property (WPSSO JSON extension required), where-as the static home page defaults to https://schema.org/WebSite.

New Plugin – WPSSO Strip Schema Microdata

wpsso-ssm-icon-round-2048x2048

If you’re using the WPSSO Schema JSON-LD Markup (WPSSO JSON) extension (and if not, you really should), you may have noticed that Google’s Schema validation tools can pickup additional incomplete / inaccurate Schema markup from your theme templates. WPSSO JSON defines its JSON-LD markup as the “main entity” for the webpage — so Google will prefer this markup over any other found in the webpage — but you may still want to cleanup that incomplete / inaccurate Schema Microdata from your theme templates. The new WPSSO Strip Schema Microdata (WPSSO SSM) extension is a Free plugin that removes Schema Microdata markup from the webpage body section automatically, leaving the Schema JSON-LD markup as the only Schema markup in the webpage.

wpsso-json-icon-round-2048x2048

WPSSO Schema JSON-LD Markup (WPSSO JSON) version 1.10.0-1 has been released, and includes several improvements for Pinterest and the Schema Recipe markup.

Although previous versions of WPSSO JSON included basic support for the Schema Recipe markup, finding an elegant way to manage ingredients — without duplicating existing theme and/or 3rd party ingredient management — was still on the To-Do list. Thanks to the helpful suggestions of a customer with a recipe website, I was able to include recipe integration features in this version.

WPSSO – Extend The Events Calendar Schema

wpsso-icon-round-2048x2048

WordPress Social Sharing Optimization (WPSSO) version 3.33.1-1 has been released, along with updates for the WPSSO JSON, WPSSO ORG, and WPSSO PLM extensions.

One of the big features for this new release is the added support for the Schema http://schema.org/Event type and its sub-types (DanceEvent, MusicEvent, etc.), along with integration of The Events Calendar plugin. The Events Calendar plugin already includes basic JSON-LD support, but the WPSSO Organization Markup (WPSSO ORG) and WPSSO Place / Location and Local Business Meta (WPSSO PLM) extensions allow you to include much more detail about the organizer (as an actual Organization instead of a Person), select a performer for the event, along with WPSSO’s standard support for images, videos, etc. The combination of WPSSO Pro and all three Pro extensions can provide extensive Schema markup about your event — see the following Schema JSON-LD markup for an example.
