Product groups are eligible for the Bid Simulator:
- Anytime after a product group is created in a Shopping campaign
- Once a budget cap has been reached for a product group
- Once the average cost-per-click (avg. CPC) is close to the maximum cost-per-click (max. CPC) bid
- When Product Listing Ads have been included in enough auctions or accrued enough impressions
Product groups are eligible for the Bid Simulator
The Bid Simulator collects and analyzes data from ad auctions on Google from the previous seven days, while considering information such as the quality of your ads, your competitors’ bids, and product data.
But keep it in mind that:
- The Bid Simulator is available when Shopping ads for a product group have been included in enough auctions or accrued enough impressions to generate a sufficient estimate of potential performance with a different bid amount. If you don’t see the Bid Simulator, you probably need to let your ads run for a little while longer or try to participate in more auctions by increasing your bids or providing higher quality product data.
- The Bid Simulator isn’t available for “excluded” product groups with no bid.
- The data displayed in the Bid Simulator for your “current” bid is a projection based on your traffic over the previous 7 days. If you recently changed your bid, you may notice notice a discrepancy between the “current” data reflected in the Bid Simulator and the actual data available in your account.

Want to increase or decrease your bids for your Shopping campaign, but not sure how it would affect your performance? The Bid Simulator can help bring clarity to how different product group bids could affect your traffic by estimating what your advertising results could’ve been over the previous seven days, if you’d set different bids. Use this tool from the “Product groups” tab to gauge what bid amount is likely to deliver the performance you want, with the budget you have. Then, quickly apply your new bid to your product groups, or across all subdivisions of a product group.
This article explains which bid simulators are available for Shopping campaigns, how they work, and how to use them in your campaign.
How it works
The Bid Simulator collects and analyzes data from ad auctions on Google from the previous seven days, while considering information such as the quality of your ads, your competitors’ bids, and product data. The tool then uses this information to estimate how certain changes to your bid would have impacted your clicks, cost, impressions, and conversions.
You can use the Bid Simulator to gauge performance for an individual product group, or for a product group with subdivisions.
Here are some things to keep in mind when using the bid simulator for a product group with subdivisions:
- You can view bid changes in aggregate and model changes for non-excluded product groups, even when individual product groups might not have enough data for this on their own.
- You can use bid scaling to see what might happen if you increased or decreased all of your bids for product groups within the subdivision by a specific percentage (10%, for example). Then you can apply the bid adjustment across these product groups with just a few clicks. Note that bid scaling isn’t available if any of the product groups are subdivided by item ID.
- You can model what happens if you changed all of your bids in the subdivided product group to a fixed value. If you choose to apply one of these product group-wide bid changes, your ad group default bids will be changed to this fixed value, and your product group-level bids will be removed.
- Bid changes across many product groups can increase traffic significantly, which could cause you to reach your budget limit. We’ll show you the projected cost for bid changes, and you might need raise your budget to make the most of your bid adjustment.
