Contoso Toys has decided to create a "catch-all" campaign with an all-products product group in it. As a best practice, how should they bid in this scenario?

The selected answer option, Have lower bids and a low campaign priority setting, is correct because when creating a "catch-all" campaign with an all-products product group, it's generally recommended to bid lower and set a low campaign priority. The "catch-all" product group typically includes a broad range of products, many of which may not be as high-priority or as well-performing as other targeted product groups. By setting lower bids and a low campaign priority, Contoso Toys ensures that this broad group does not dominate the campaign budget or outbid more relevant product groups. This approach helps manage the campaign efficiently, directing more resources to the specific products that are likely to generate the highest returns, while still allowing the "catch-all" product group to run with minimal impact on the overall performance.
