What is Google Merchant Centre?
Google Merchant Centre is Google's service they use to enable you to manage your products on their platform.
Using our Google Shopping feed, you can simply give Google Merchant Centre a special URL to an "XML file" which means that every time you add/update/delete items from your website they'll get updated on Google.
(not there can be a delay based on how frequently they update)
To use it, simply go to the "Marketplaces" section of your website manager.
