WPSSO Core | The Complete Meta Tag and Schema Markup Solution


Make sure your content looks great on social sites and search results, no matter how your URLs are crawled, shared, re-shared, posted, or embedded:

WPSSO creates meta tags and Schema markup for Facebook / Open Graph, Pinterest Rich Pins, Twitter Cards, Google Knowledge Graph, Google Rich Results (aka Rich Snippets, Structured Data), WhatsApp and Messaging Apps, Mobile Web Browsers, WordPress REST API, LinkedIn / oEmbed data and more — including complete markup for image SEO, video SEO, extensive e-Commerce product markup (for WooCommerce and others), mobile store apps, 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 WordPress content, supported plugin data, and service API data.

Uses your existing WordPress content, plugin data, and service API data:

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

WPSSO can be used as your one and only social and search optimization plugin, or in combination with your favorite SEO plugin to improve its meta tags and Schema markup (including, All In One SEO Pack, Jetpack SEO Tools, Rank Math SEO, SEO Ultimate, The SEO Framework, WP Meta SEO, Yoast SEO, and more).

Customize the plugin settings for different languages:

Text, image, and video related options are WordPress language / locale aware, which means you can easily switch languages and customize these options for different front-end webpage languages.

Coded for maximum WordPress performance and compatibility:

WPSSO makes full use of all available caching methods — along with offering advanced caching features like pre-seeding in background. WPSSO Core and its complementary add-ons load only the libraries and classes they need, keeping their code small, fast and light. All code is fully tested and compatible with the latest version of WordPress and PHP v7.x (WordPress v4.2 and PHP v5.6 or newer is required).

Users Love the WPSSO Core Plugin

★★★★★ — “This plugin has been a lifesaver in terms of making our images and links and descriptions look beautiful everywhere we post them! It’s so easy to use and the preview functions are incredibly helpful.” – lotusblooms

★★★★★ — “What a fantastic plugin. If you want to fix all the errors in search console for structured data, this is the plugin to use. Love it.” – goviral

★★★★★ — “This plugin saves me so much time, and it has really lifted my SERP rankings. Most of my keywords I now rank 1-3 position. I also noticed after about a week that my impressions have gone up at least 75%. I upgraded to the pro version which gave me even more options.” – playnstocks

★★★★★ — “Yoast on steroids! As an SEO marketer, I love using Yoast for my basic on-page SEO. But Yoast only allows you to enter basic Open Graph social settings. This plugin gives you SO many more options on completing the Open Graph for Facebook, Twitter cards, Pinterest etc. If you use WordPress, I totally recommend using this plugin to help with better rankings in the SERPS!” – gregmontag

Notes and Documentation


This plugin deleted/wiped out all my content!!! Do not bother with this plugin, thank god I have backup and was able to restore. Cannot be trusted
Exactly what I needed. Unlike Yeast SEO, the free version gives you all necessary options to add required meta info to web pages.
This plugin does all the work on its own. Just set it and forget it. No heavy duty setup and incorporates well with my website Theme. It makes it easy for site users to share and follow. Keep up the good work. Thanks for making it available to us.
Great program, great results and great support! five stars!
Have been using this plugin for well over 2 years now. Very broad - you will not need anything else. Developer appears to have dedicated their life to it which makes it, in my humble opinion, a perfect SEO plugin.

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).
