What is the difference between a private and a public catalog?
A public catalog will be indexed by search engines like Google and Bing, while a private catalog will be ignored by them. A private catalog will therefore only be accessible to people who know it's link which is perfect when you want to send a catalog to a specific customer or if you want your wholesale prices to remain private. If you want to share your catalog to as many people as possible, make it public.
In order to change the privacy setting of your catalog, click on the toggle button located on the top bar menu while you are editing your catalog.
