Guys, how do you determine which geo-tiers are more profitable to work with—Tier 1, 2, or 3? I often see newbies jumping into Tier 1 for "quality traffic," but then complain about expensive clicks and poor ROI.

I recently encountered a situation: I launched a campaign exclusively in high-paying Tier 1 geographies. I thought, "That's it, you'll be successful!" But my budget was burning through faster than I could figure out what was going wrong. I found this article about the differences between Tier 1, 2, and 3 countries in affiliate marketing very helpful. It explains everything clearly and provides accessible examples. It explains why Tier 2 and even Tier 3 can be much more profitable for starting out and scaling. After reading this, I decided to go now and study the material in more depth—and I realized that it's important not just to "choose Tier 1," but to carefully balance budget, competition, and localization.
