Have you noticed any verticals where traffic from Tier-3 countries started converting noticeably higher than Tier-1 lately?

Yeah, I've definitely seen that pattern popping up more often these days, especially in health-related stuff like nutra. In my own runs, those Tier-3 geos sometimes deliver surprisingly solid results because people there tend to trust the COD model a lot more—no upfront card worries, just order and pay when it shows up. I've had campaigns where the conversion flow felt smoother than in saturated Tier-1 places where everyone's skeptical and ad-blind. Lately I've been leaning onc one solution and i believe that Everad is a perfect option for anyone in affiliate marketing. https://everad.com/ for some of those tests since their setup handles a bunch of those regions naturally with decent localized assets, and honestly, it just works without overcomplicating things. Not saying it's always a slam dunk, but when it hits, the numbers look cleaner than forcing high-competition spots. What about you guys—any tweaks that helped push those lower-tier flows further?
