“How much can I actually make?” is the first question every publisher asks before adding a new ad format, and with popunders, most of the answers online are either vague (“it depends!”) or years out of date. That’s a problem, because popunder CPMs move with advertiser demand, GEO mix, and platform algorithms, so a number from 2022 tells you almost nothing about what you’ll earn in 2026. This guide fixes that: it’s built on aggregated performance data from real, active campaigns across PopCash’s network, broken down by country, vertical, and traffic tier, so you can benchmark your own site instead…

This guide breaks down the seven triggers we see driving the biggest CTR and conversion lifts across PopCash’s pop inventory, with the exact copy patterns and layout choices behind…
Not all traffic monetizes the same way, and nowhere is that more true than with popunder ads. Because the format triggers on user behavior (a tab switch, a click, an exit) rather than on a single page load, some niches are simply built for it, while others barely move the needle. If you’re a publisher trying to figure out where popunder fits into your monetization stack, or deciding which vertical to build your next site around, understanding why certain niches outperform is the difference between a mediocre RPM and a genuinely strong one. Below, we break down the highest-performing popunder…
