In episode 155 of Semantic Mastery's weekly Hump Day Hangouts, one participant asked whether having Rich Plugins for FB and GMB reviews allows one to add review schema to a homepage with a review slider.
The exact question was:
I bought the Rich Plugins FB and GMB reviews that BB mentioned a while ago. I've added a GMB review slider right on the homepage. I'm new to Schema, but would I be able to add review schema to the page because of this? If so, is there anything I should watch out for?
In the video, Bradley mentioned that if you have bought the pro version of Rich Plugins, it automatically adds schema markups and structured data on the website. One should remember to select the proper option on the Rich Plugin setting so that it can properly mark up the structured data and provide rich snippets in search results. Bradley also highly suggest contacting the developer for any issues.
