Case: a conversion-cap rule that stopped overspending a capped offer by $900/day

The problem: an offer had a daily cap of 50 conversions. Past the cap the network silently stopped approving, but the tracker kept sending traffic to it at full tilt — paying for clicks that could never convert.

What the logs showed:
— On a typical day, the 50th conversion landed by 2pm
— From 2pm to midnight the campaign spent ~$900 driving traffic to a dead offer
— CR after the cap was hit fell to near zero, dragging the daily average down

The rule we built in Keitaro:
1. Set the offer's conversion cap to 50 inside the tracker, not just on the network's side
2. Configured the flow to redirect traffic to a backup offer once the cap was reached
3. Added a second rule to resume the primary at 00:00 when the network's cap reset
4. Set a notification at 45 conversions so the buyer had a heads-up

Outcome:
— Post-cap spend on the dead offer dropped to zero
— The backup offer captured ~$600/day of that redirected traffic at a positive ROI
— Net swing roughly $1,500/day in EV between stopped waste and recovered revenue

Mirror every network cap inside the tracker and set a fallback. The tracker should never feed a closed offer.
