Supports over 500 different Schema (aka Schema.org) types and sub-types:

Google Rich Results with JSON-LD structured data for Articles, Carousels (aka Item Lists), Claim Reviews, Events, FAQ pages, How-Tos, Images, Local Business / Local SEO, Organizations, Products, Ratings, Recipes, Restaurants, Reviews, Video Objects, and much more.

Reads your existing content, plugin data, and service API data:

There's no need to manually re-enter descriptions, titles, product information, and re-select images / videos like other SEO and Schema markup plugins.

Provides comprehensive Schema JSON-LD markup for posts, pages, custom post types, terms (category, tags, etc.), custom taxonomies, user profile pages, search result pages, archive pages, and Accelerated Mobile Pages (AMP) pages - including image SEO, video SEO, local business, organization, publisher, person, author and co-authors, extensive e-Commerce product markup, product variations, product ratings, aggregate ratings, reviews, recipe information, event details, collection pages, profile pages, search pages, FAQ pages, item lists for Google's Carousel Rich Results, and much more.

Most complete Schema JSON-LD markup for WooCommerce products:

Note that WooCommerce offers incomplete Schema markup for Google Rich Results by default. The WPSSO Core Premium plugin and this add-on provide a solution by offering complete product meta tags for Facebook / Pinterest and complete Schema product markup for Google Rich Results - including additional product images, product variations, product information (brand, color, condition, EAN, dimensions, GTIN-8/12/13/14, ISBN, material, MPN, size, SKU, volume, weight, etc), product reviews, product ratings, sale start / end dates, sale prices, pre-tax prices, VAT prices, shipping rates, shipping times, and much, much more.

Fixes all Google Search Console / Structured Data Testing Tool errors:

A value for the headline field is required.
A value for the image field is required.
A value for the logo field is required.
A value for the publisher field is required.
The aggregateRating field is recommended.
The brand field is recommended.
The headline field is recommended.
The image field is recommended.
The mainEntityOfPage field is recommended.

This Product is missing a global identifier (e.g. isbn, mpn or gtin8).
No global identifier provided (e.g. gtin mpn isbn).
Not a known valid target type for the itemReviewed property.
And more...

Some Schema property values may require data from WPSSO Core Premium supported third-party plugins and service APIs.

Google regularly updates and changes their Schema markup requirements - WPSSO JSON Premium customers can also open a Premium support ticket for timely assistance with any new Google testing tool errors.
