If all your products are listed on a central, index page somewhere then you can answer "yes" to this question.
For instance, you have an online shop which lists out all your product titles even though the products themselves all have separate sales pages.
Examples:
https://www.perrymarshall.com/products/
http://www.sacredscience.com/store/commerce.cgi
http://www.kinoyoga.com/shop/
If you have no central, index page or your products are scattered across multiple selling platforms, please answer "no".
