Enforcing your break-even ceiling automatically
Instead of manually updating bids when auction prices fluctuate, you can encode this break-even ceiling directly into Visprisca using Rule Engine Optimization (REO). Visprisca will dynamically bid up to your optimal price without ever crossing your margin threshold.
Rule Example: "If clearing CPM > $24.00, drop bid multiplier or pause placement."
