There are three different Rule Types in your Sales & Orders account

Update Bids

These rules will only operate to adjust product bids for either Bing or Google. Rules can be operated separately or combined for either channel.

Add Products

These rules will only operate to add products to campaigns when they don’t already exist (such as when new products are added to your feed and sent to Merchant Center). Rules can be operated separately or combined for either channel.

Advanced Users: Tag Rules

Tag Rules are a new way for you to connect the dots between campaign/product performance and your product feed. Tag Rules are only available to Full Access Plan users on $50/mo plans and higher and who also have access to the Advanced Modify Add-on for the feed tool.
