 * In Google Structured Data Testing Tool, the website that I provide support with,
   the [nutrimedical.gr](https://www.nutrimedical.gr) is getting the errors below.
 * Are those errors going to be fixed if I install WPSSO JSON?
 * Thanks

 * Those look like warning and errors related to a Schema Article type or sub-type.
   And yes, WPSSO Core and its WPSSO JSON add-on would fix those.
 * And seeing as you use WooCommerce, you’ll probably want the WPSSO Core Premium
   plugin for its WooCommerce integration module, and the WPSSO JSON Premium add-
   on for its Schema Product support.
