During Cobiro's setup process you can select all the products you want to have included in your feed for Google Shopping. This feed will fetch information about your products from your website on a daily basis and look for updates of specific product attributes (prize, availability, size, etc.). All products you have not selected during the Cobiro setup will not be part of your Shopping campaign. When you modify, add or remove a product in your online store that is also part of a category that you selected to advertise during the Cobiro setup, all changes will be automatically integrated into your Cobiro Shopping campaign. When you update products that are not part of your initial category selection you need to contact Cobiro's Customer Success Team and inform them about your changes. The same applies when you want to stop or start advertising a whole category.
