There's no need to select or create templates, manually reenter descriptions, titles, product information, or reselect images and videos.
WPSSO can use your existing WordPress content, including custom post types and taxonomies, enhanced user profile data, Media Library image and video information, third-party plugin data, and remote service APIs (Bitly, Facebook, Shopper Approved, Stamped.io, Vimeo, Wistia, YouTube, and many more).
Supports over 500 different Schema types:
WPSSO provides comprehensive Schema 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 Rich Results Carousel, and much more.

WPSSO can be your only social and search optimization plugin, or can improve the structured data of another third-party SEO plugin (like All in One SEO Pack, Jetpack SEO Tools, Rank Math SEO, SEO Ultimate, SEOPress, The SEO Framework, WP Meta SEO, Yoast SEO, and more).

Release Schedule
New versions of the plugin are released approximately every week (more or less). New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.
See release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.
Version Numbering
Version components: {major}.{minor}.{bugfix}[-{stage}.{level}]
- {major} = Major structural code changes / re-writes or incompatible API changes.
- {minor} = New functionality was added or improved in a backwards-compatible manner.
- {bugfix} = Backwards-compatible bug fixes or small improvements.
- {stage}.{level} = Pre-production release: dev < a (alpha) < b (beta) < rc (release candidate).
Standard Version Repositories
Development Version Updates
WPSSO Core Premium customers have access to development, alpha, beta, and release candidate version updates:
Under the SSO > Update Manager settings page, select the "Development and Up" (for example) version filter for the WPSSO Core plugin and/or its add-ons. Save the plugin settings and click the "Check for Plugin Updates" button to fetch the latest version information. When new development versions are available, they will automatically appear under your WordPress Dashboard > Updates page. You can always reselect the "Stable / Production" version filter at any time to reinstall the latest stable version.
