Explanation:
Campaign Priority determines which products you want to get displayed from in case you have multiple Shopping campaigns running with similar products. In that case the deciding factor will not be bid, but the campaign priority if you set it to High.
When you have the same product in multiple Shopping campaigns, you can determine which campaign should participate in the auction for that product with campaign priority. Your campaigns already have a priority: Low. But you can change this priority to Medium or High. These priorities determine the bid for any product that the campaigns share.

Campaign priority is useful when you’re advertising the same product, for the same country, in multiple Shopping campaigns.
This article explains how campaign priority works and how to set it up for your Shopping campaigns.
Before you begin
To use the campaign priority setting, you first need to Create a Shopping campaign.
Remember campaign priority is only important if you have multiple Shopping campaigns that promote the same product.
How it works
When you have the same product in multiple Shopping campaigns, you can determine which campaign should participate in the auction for that product with campaign priority. Your campaigns already have a priority: Low. But you can change this priority to Medium or High. These priorities determine the bid for any product that the campaigns share.
Campaign priorities determine bids using these rules:
- The highest priority campaign will bid. If one campaign has a higher priority than the others, the campaign with the higher priority will bid. For example, imagine 2 campaigns share a product. One campaign has a High priority, and the other has a Medium priority. The bid from the High priority campaign will be used, even if the bid in the Medium priority campaign is set to a larger amount.
- If the highest priority campaign runs out of budget, the lower priority campaign bids. If the campaign with the highest priority runs out of budget, the next lower priority campaign will place the bid. Continuing with the previous example, when the budget for the High priority campaign is used up, the bid from the Medium priority campaign will be used.Note about ad delivery: When you set a campaign to use the Standard delivery method, your budget will be spread evenly throughout the day. So to reserve funds for later in the day, a High priority campaign might not participate in an auction even if the budget is not yet exhausted. Instead a lower priority campaign that is not reserving funds might participate in the auction. Learn more about ad delivery.
- When multiple campaigns have the same priority, the highest bid is used. If multiple campaigns all have the same priority, the campaign with the highest bid for that product will participate in the auction. For example, if 3 campaigns share the same product and have a Low priority, the highest bid from any of the 3 campaigns will be used.
