<b>Heard: floor prices are quietly eroding on mid-tier pop sources</b>
The pattern: a source holds a $0.80 floor for tier-1 mobile, then six weeks later you're winning the same geo at $0.45 with no volume gain. That's not your bidding getting smarter — that's the source backfilling with resold inventory and padding impression counts.
Our read: when win rate climbs but conversion-per-thousand stays flat, you're buying dilution, not a discount. Pull a sub-source breakdown before you scale on the 'cheaper' floor.
