WPSSO Core – Advanced Meta Tags and Schema Markup for Facebook, Pinterest, SEO and More


What makes WPSSO Core better?

Uses your existing content for meta tags and Schema markup:

There’s no need to manually re-enter descriptions, titles, product information, select images / videos, etc. — WPSSO Core reads all your existing WordPress content automatically, and you can optionally fine-tune and customize just about anything and everything. 😉

WPSSO Core is language / locale aware, allowing you to customize your site information, social pages and Knowledge Graph for different languages!

Creates complete and accurate meta tags and Schema markup:

WPSSO Core offers meta tags and Schema markup for Facebook / Open Graph, Google’s Knowledge Graph and Rich Card SEO, Pinterest Rich Pins, Twitter Cards, Weibo and more — including complete image markup, video markup, extensive eCommerce product markup, author profile / authorship, co-authors, publisher information, local business markup, aggregate ratings, reviews, recipe information, event details, and much, much more — all from your existing content!

Includes advanced quality control features and options:

WPSSO Core checks for minimum / maximum image dimensions and aspect ratios, shows notices for missing and required images, verifies your webpages for duplicate meta tags, validates theme header templates for correct HTML markup, warns of any missing PHP modules, and checks 3rd party plugin settings for possible conflicts.

Offers special meta tags and features for Pinterest:

WPSSO Core provides a specific image and image dimensions for the Pinterest Pin It button, excludes non-relevant images from being detected by Pinterest, and prevents conflicts between incompatible Pinterest and Facebook meta tag values.

Integrates and improves your favorite SEO plugin:

WPSSO Core specializes in providing all the meta tags and Schema markup social sites and search engines need — and, if you desire, you can continue to use your favorite SEO content / keyword analysis tools without any conflicts! The Pro version even comes with special integration modules for All in One SEO Pack, The SEO Framework, WP Meta SEO, Yoast SEO, and more.

A meta tag and Schema plugin for today and tomorrow:

WPSSO Core is 100% compatible with the upcoming Gutenberg block editor in WordPress 5 (expected in August 2018)!

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).
