Popunder ad formats – classic vs tab-under vs mobile

What would you choose?

Not all popunder formats perform the same. Classic popunders open behind the current window and reveal themselves when the user closes their tab. Tab-unders are similar but live inside the browser tab itself. Mobile popunders behave differently because phone browsers handle windows in their own way. I've tested all three across multiple verticals. For dating offers, classic popunders on desktop still work best for me. For mobile subscription offers, mobile popunders convert way better because the user flow is smoother. The platform I'm using now supports all three formats in one dashboard so I don't have to juggle multiple accounts.
