For Tier 3 gambling push traffic, a good CPC range usually falls between $0.001 and $0.005. These geos tend to have cheaper traffic, so starting low makes sense. It allows you to collect data without spending too much. If you're testing new creatives or angles, it's safer to begin on the lower end and slowly increase the CPC if you see good engagement. Since Tier 3 countries often convert well with simple landers and catchy hooks, keeping CPC low helps you stay profitable, especially if you're working with a low-payout offer. Make sure you monitor the CTR closely and look at conversions. A cheap CPC with no conversions might still mean wasted budget. Some platforms also offer automated bidding—just be careful with that in these regions. What kind of CPCs have you seen in your campaigns?
