It behaves similar to Category. But if you do not have any Tag then this field is populated with Sub category. Visitors can filter products based on sub category as well along with category.
This option governs what you want to display below product image. You can display Product Title , Rating and Review count or any combination of them.
Add to Cart
If this option is enabled Add to Cart button is displayed on Shop page below the Product Image and options you selected in Show option.
You can change the Text displayed on Category drop down. For example if you have Music store then you can change it to something meaningful and matching to your content like Artists. So visitors can filter the Music with different Artists.
This one is similar to Category Text but is applicable for Tag drop down (or sub category drop down).
Products per page
This option helps you decide number of products you want to display on first page of Shop. This number should not be too large as it will impact page load time. This number should not be too small as well. You can set this number along with Product Image size as per your store need.
