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


What makes WPSSO Core better?

Makes sure your content looks great on all social and search sites – no matter how it’s crawled, shared, re-shared, posted, or embedded!

WPSSO Core makes sure that all social crawlers, search crawlers, web browser extensions, mail and messaging apps (Facebook Messenger, iMessage, Skype, WhatsApp, etc.), and embedded object / iframe content, always get accurate and complete information about your webpage content, business, and authors.

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 your existing content automatically and offers fine-tuning and customization options for just about anything and everything. 😉

WPSSO Core is language / locale aware, which means you can customize your site information, social page URLs and Knowledge Graph for different languages!

WPSSO Core and its optional add-ons offer meta tags and Schema markup for Facebook / Open Graph, Google’s Knowledge Graph SEO, Google Rich Card SEO, Google Merchant SEO, Mobile Web Browsers, Pinterest Rich Pins, Twitter Cards, Weibo and many more — including complete markup for images, videos, extensive eCommerce product markup, mobile 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 content!

Includes advanced quality assurance features and options:

  1. Checks for minimum / maximum image dimensions and aspect ratios.
  2. Shows notices for missing and required images.
  3. Verifies webpages for duplicate meta tags.
  4. Validates theme header templates for correct HTML markup.
  5. Checks and warns of any missing PHP modules.

★★★★★ — “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

Frequently Asked Questions

Advanced Documentation and Notes


This Plugin Set Does It All… and More! Great Support

We needed to fix up the JSON-LD / Schema markup on our site, and after some research, landed on WPSSO. I don't regret that decision one bit -- this software set does EVERYTHING (we've had to buy a couple of the pro plugins to get what we want). Our blog's now compliant and the search engines can properly sniff it out, unlike before. WPSSO's Support is extremely responsive, and the support / coding staff has even added two sets of functions that helped us with our theme programming! Best WordPress Plugin support I've ever had. Thanks WPSSO crew - keep it up!

Great Puglin

This plugin solve so much problems to begins webmasters in SEO and Markup and more, very intuitive, easy to instal adn config. recommend the premium, but the free is amazing if you no need premium features. 5 stars

Kudos for a great, useful and well-written plugin!

The WPSSO is a *really* well written piece of code. I had a specific issue a third-party plugin which had an issue with it's own filters/actions and the author of WPSSO (JS) helped them out directly. Improvements to the codebase of any one plugin benefits us all. Much kudos for an active opensource attitude. Much kudos for this plugin!

Pricey Bait and Switch

As a satisfied long-time user of NGFB Pro I am totally disgusted with WPSSO. It may be a quality product as its predecessor product was but one has to ask why and what benefit do users such as I get from this "forced" move other than the opportunity for Morrisset to replenish his wallet with his customers $$$$. From a simple straight forward plugin to a "core" plugin that does nothing much unless additional plugins (the ones needed for it to provide the same functionality as NGFB are not free, including the Core Pro) are installed. Documentation is less than useless, none of the settings for the multitude of social media are explained or even mentioned (the user is supposed to be the expert in these, obtaining this information from where, who knows,) installation instructions, especially for NGFB users, is lacking in useful guidance on steps to take to remove NGFB and whether settings will be lost when WPSSO is installed. The simplest of questions submitted to support receive curt, unhelpful, dismissive responses. In short, WPSSO seems to be a solution in search of a problem with no discernible benefit to the user. If you are a NGFB user and happy with it, don't waste your money on WPSSO. Recommend looking for another plugin.
