Vivian owns an art supply store and traffic for her “painting” product group is increasing. To optimize the performance of her painting products, Vivian should:
Update the inventory by removing certain products
Subdivide the product group and move budget allocation to the best performing products
Add promotional text that says “Best selling” to the ad group
Increase the maximum cost-per-click (max. CPC) bid for all products
You can subdivide up to 7 levels for each product group in any order you want. You can have a product group for all your products and bid the same amount for all of them. In the opposite way, you can also have smaller product groups organized by brand or product category. Keep in mind that you can’t set a bid on a product group that has been subdivided–you’ll set bids on the product groups without subdivisions.
