Simple set up and works

I have tried a few different Schema apps, one was never updated, and had little support to explain how to set it up. Another was extremely complicated to set up, and was not free after you set up a few pages.
This Schema app is simple to set up, gives you special markup for contact pages, and about pages. It also allows you to give a SameAs for your articles.
Most importantly, the markup doesn’t give any errors in the structured data testing tool. Really well done app. I think its the best one for Schema on WP
