I've got an ecomm client that is experiencing some supply chain uncertainties related to their product. It's caused us to start thinking about throttling ad spend as a result. I want to do it in such a way as to not throw off the algorithm and force it to relearn. Right now we're spending around $450/day in a single CBO campaign. Which of the following should i do? A - Turn off ads completely until issue is fixed, then turn back on, never adjusting daily spend B - Cut budget in half in the short term, then when supply chain issue is fixed just double the budget back to where we were C - Keep daily budget the same but pause the campaign every day when 50% spend is reached
