WPSSO Core extension to add Schema JSON-LD / SEO markup for Articles, Events, Local Business, Products, Recipes, Reviews + many more.
Google’s Structured Data Testing Tool and/or Google’s Search Console for site owners may report the following errors for the default Schema JSON-LD markup offered by WooCommerce:
WooCommerce manages information on product Availability (aka Stock), Prices, SKU, etc., but additional WooCommerce product attributes must be created to provide more product information for Google.
The WPSSO Core Pro plugin (and its WPSSO Schema JSON-LD Markup Pro add-on), for example, include a variety of WooCommerce product attribute values in its Schema markup, including the product Brand, Color, Condition, EAN, GTIN-8, GTIN-12, GTIN-13, GTIN-14, ISBN, Material, MPN (aka Manufacturer Part Number), Size, and Gender.
There are several ways to add aggregate ratings — as I’ll explain below — but first, before we dive into the “How”, let’s talk about what an “aggregate rating” actually is. ;-) The Schema.org website defines the Schema aggregateRating property value as:
The overall rating, based on a collection of reviews or ratings, of the item.
It’s been a very productive two weeks of coding for both the WPSSO Core plugin, and it’s WPSSO Schema JSON-LD Markup add-on.
On April 26th – just two weeks ago – WPSSO Core v4.0.0 was released, which included support for the new Gutenberg editor. Since then, WPSSO Core v4.1.0, v4.2.0, and v4.3.0 were also released (the last one just today), along with WPSSO JSON v1.25.0 and v1.26.0.
In case you missed all the update notices and posts about those versions, the following is a quick summary of the big changes and improvements in both WPSSO Core and its JSON-LD add-on. And at the end of this post, you can also find a summary of our release schedule philosophy, and why we chose to release four big improvements, in four different versions, in just two weeks. ;-)
The upcoming WPSSO JSON Premium v1.18.0 release (ETA Nov 11-12th) includes new Schema Job Posting options in the Social and Search Optimization metabox and support for the Simple Job Board plugin (along with pre-existing support for the WP Job Manager plugin from Automattic). See the WPSSO JSON changelog for more details.
You’ll find three new Schema Job Posting options in the Social and Search Optimization metabox:
The WPSSO Schema JSON-LD Markup (WPSSO JSON) v1.13.0-1 extension for WPSSO has been released (see the complete Changelog here) — this latest version adds several custom Recipe Instructions and Nutrition Information options to the Social Settings metabox, along with including some new integration modules for WP Recipe Maker and WP Ultimate Recipes.
WPSSO Schema JSON-LD (WPSSO JSON) extension v1.12.0-1 has been released — this new version adds WooCommerce product reviews to the Schema Product markup, along with adding WordPress comments and threaded replies to the Schema CreativeWork markup and its sub-types (Article, BlogPosting, WebPage, etc.).
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 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.
WPSSO version 3.25.0 has been released, along with a new WPSSO Schema JSON-LD Markup extension plugin.
The last three versions of WPSSO — including this one — contain significant changes to the JSON-LD code. WPSSO continues to provide excellent support for Google’s WebSite Information, Site Publisher / Organization Social Profile, and Person Social Profile Structured Data. And in version 3.25.0, WPSSO complies with Google’s markup standard even more by including this information only on the home page (allowing you the flexibility to use these Schema types on other pages with different values).
You’ll want to review the latest Google / Schema related options on the SSO General settings page, to make sure the settings reflect your preferences — for example, you may want to select the Site Owner to use in the Person Social Profile Structured Data markup.
All non-social related JSON-LD markup — like schema.org/Article markup for example — is provided by a new WPSSO Schema JSON-LD Markup (WPSSO JSON) Pro extension. You can select the Schema type for each WordPress Post Type on the SSO General settings page, under the Google / Schema tab. The new WPSSO JSON extension creates appropriate JSON-LD markup for all supported Schema types. WPSSO JSON also comes with an additional Schema Type option for the Social Settings metabox, allowing you to customize the Schema type for each Post / Page.
