For a brand selling lots of products with a budget, what is the ideal number of products per category to start with in a PLA campaign?

The selected answer option is correct because when starting a PLA (Product Listing Ad) campaign, it is ideal for a brand to begin with 5-30 products per category. This range provides a balanced approach that allows the brand to test a reasonable number of products while maintaining a manageable campaign structure. Starting with 5-30 products per category ensures that the campaign has enough diversity to reach a broad audience and gather meaningful data on performance, without overwhelming the advertiser with too many variables. It also allows for optimization based on which products perform best, making it easier to adjust bids, targets, and strategies as needed. Starting with just one product may not give enough variety for robust performance insights, while starting with 100 products could lead to a more complex campaign that is harder to manage and optimize effectively, especially with a limited budget. Therefore, 5-30 products per category strikes a good balance for initial testing and optimization in PLA campaigns.
