Beyond Excellent Support!

Before trying WPSSO Schema JSON ID, I wrote a question on the weekend, not expecting a reply until Monday or later. Well, JS replied within 20 minutes! The installation was straight-forward. The configuration was intuitive and easy to understand. I could refer to their helpful documentation if I had questions about a specific item. I did as much of the setup as I could, but when I got stuck, I contacted support and got quick replies each time! Because of the unique structure of my site and the number of pages, I had to create a custom script. Luckily, JS was there to help and he was fantastic! Everything's now ready to go. And it's still the weekend!

Simplifies schema

Works well, simplifies the complexities of schema markup for WordPress users, has informative messages. I went for the paid version up front, so can't really review "free" - Bit pricey, but at least it's one time, not recurring.
