Before you start we recommend re-syncing your shopping feed to Optmyzr on the 'Manage Merchant Feeds' page. This will allow Optmyzr to get the latest state of the feed to compare against the shopping campaign.
Setting it Up
Select a shopping campaign from the campaign tree on the left. This will run the refresher on all active ad groups in the campaign and show results.
By default, the new product groups and ad groups created will inherit the bids from their respective level at Everything Else node. You can choose to overwrite the bids using the "Set Bids for Selected".
To do so, review the product groups to be added (Additions), select the ones you want to change bids for, and press "Set Bids for Selected". This specifies that only the new additions will get these new bids.
Send Email once Applied
Once you click apply, you will have the option receive an email once optimization is applied. This way, you won't have to wait for the process to finish loading. You'll be notified if there were any errors, and/or if the changes were applied successfully.
The Shopping Refresher can be automated to run on a schedule, allowing you to re-sync your feed automatically.
