The tool helps you sync your shopping campaigns with your product feed by removing the product groups that are no longer part of your product feed and creating product groups for products that were added.
The Shopping Refresher only recommends product groups when the associated 'Everything Else' group is included. If it is excluded, the tool will ignore new products that were added to the feed under that split because the assumption is that anything that falls into 'Everything Else' should not show ads.
Right now, the optimization works only at ad group level. If you would like to refresh multiple ad groups simultaneously, you can try the Shopping Refresher Pro
You can access the Shopping Campaign Refresher optimization here.
Before you start using the optimization, we recommend resyncing your shopping feed in Optmyzr on the "Manage Merchant Feeds" page. This will allow Optmyzr to get the latest state of your feed.
Once the system displays the results, you will have the option to set bids for the new and the existing product groups. You can choose to set a bid manually or to inherit the bid from the parent product group.
