Users Love the WPSSO Core Plugin

★★★★★ – « Unlike competitors, you can literally customize just about every aspect of SEO and Social SEO if you desire to. […] This plugin has the most complete JSON-LD markup out of any of them, so you won’t have any errors and warnings in search console for WordPress or WooCommerce sites. You can go crazy customizing everything, or you can just set and forget. There aren’t many plugins that allow the best of both worlds. » – kw11

★★★★★ – « This plugin makes getting sites structured data ready extremely easy, and it works flawlessly without any issues. It shows messages on the top bar every step of the way to alert you of any issues until everything is set up correctly. It made all my ecommerce products pass Google’s validation tests. Great work. » – marguy1

★★★★★ – « 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

Broke my product page. While this was resolved with an update, who knows how long my product page was reporting errors to clients. I despise any plugin that causes fatal errors. TEST TEST TEST TEST TEST. We are not your guinea pigs.

After ages trying to figure out how to fine tune the SEO of my website and failing miserable I came across this plugin. That just has all the settings I needed a more. At first the warning flashes seemed intimidating but its just trying to help by shouting THIS IS NOT DONE FIX IT. They you do and then no more warning message.

Have used numerous plugins that claim to be able to boost our SEO optimization, etc etc. Ended up with WPSSO over year ago and wish we’d started using it earlier.  While it is not the easiest plugin to utilize initially as you really do need to have a basic understanding of Schema types and how they are best utilized and implemented. However, once you get it dialed in, WPSSO Core and the various Premium editions we use have really helped with our visibility with search engines as well as social media sites understanding our content.  Plus, the support for the Premium level is fantastic! Nothing is without a few hiccups, and the WPSSO team does a stellar job of working with me to improve the plugin when needed.

I've been asked to rate this plugin. I have had it for a week or so. I am unsure about its benefit to my site. I don't see great advances in increased visits to the site. There might have been some improvements to the visits but it is unclear. The sole purpose of the plugin is to increase hit rate. Hence 3 stars. It is also complicated to set up. And you get tons of messages. Don't really like it.

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.

  • {minor} = New functionality was added or improved in a backwards-compatible manner.
  • {bugfix} = Backwards-compatible bug fixes or small improvements.
