Confused about CCA bidding? Think of it as a bake sale.
You walk up and say: "I have $100 to spend, and I won't pay more than $5 per cookie."
That's your two settings:
max budget = $100 (how much you commit)
max FDV = $5/cookie (your price ceiling)
As long as cookies cost $5 or less, you keep buying. The moment everyone's fighting over cookies and the price crosses $5 โ you stop. Unspent money sits until you rebid or claim it back.
So get in early. Pay less. Be smug about it later. ๐ฅ
