Just to see what happens!
Maybe, like eBay, you'll find the answer is "not much."
Remember the Parable of the Pizzeria - are your ads creating new sales, or just claiming credit for sales that were already going to happen?
Give yourself a month to answer these questions:
- What's the true impact of eliminating paid advertising?
- How does this compare with the claimed ROI of my paid ads program?
- What would I do with my ads budget if I didn't need it?
