Finding your true bid floor: walk it DOWN, not up.

Finding your true bid floor: walk it DOWN, not up.
Everyone starts low and raises till volume comes. Backwards.
Start at a bid you KNOW wins auctions → get volume → then lower in 10% steps every day delivery holds.
The step where volume drops off a cliff = your floor. Sit one notch above it.
Starting low means you never learn if the offer converts or just can't buy traffic. Walk it down.
