Currently I have my standard shopping campaign set up in "single product ad groups" so one SKU per ad group. This seems to be working great since I can easily identify and weed out negative keywords and control max CPC at the SKU level.

One thing I cannot control is the overall budgeted spend at the SKU level. I have SKUs on my website that are $50 and others that are $8000. I want to be able to control the amount that I'm budgeting for each of these independently. An $8000 SKU will obviously need and deserve a larger ad budget.

In your experience, does it make sense to split your stores SKUs up into separate campaigns to get that level of control over spend? Is there a third option that I'm not aware of yet since I'm relatively new at this (in-house not agency).

Thanks!
