Confirmed: blacklisting 140 zones turned a −12% campaign to +24%
A pop buyer was deep red on a finance offer across a major source, down −12% over $9k spend. Instead of killing it, they pulled the zone-level report.
9% of zones were generating 80% of the loss — bot-heavy 'site' placements.
— blacklisted 140 zones (out of ~1,600)
— same offer, same source, same budget
— ROI flipped to +24% within 6 days
The campaign was never bad. ~140 zones were poisoning the whole average.
— confidence: high
