Rich Snippets

Which rich snippets do you want?
https://developers.google.com/structured-data/rich-snippets/

If you want rich snippets for products then you need an e-commerce plugin that supports Schema.org markup for products. If you want rich snippets for reviews then you need a reviews plugin that supports Schema.org markup for reviews.

Reviews probably. Can you point me in the right direction for both?

These are just two plugins that do this but you’ll want to do your own research:
WooCommerce for products
WP Customer Reviews for reviews

Thank you. I will look into it and discuss it with my team and client.
