Pop Under Traffic
Been running pop under campaigns for about two years now, and the biggest mistake I made early on was choosing networks purely based on price without checking actual inventory depth. CPM means nothing if impressions dry up after a few hours. Started tracking available volume per country before committing to any network, which changed everything for my ROI. For anyone serious about scaling, check https://dao.ad/en/traffic-volume/pops — they publish live impression counts by country, which makes planning a lot more predictable. India alone is sitting at over 400 million daily impressions on their network right now. For tier-2 and tier-3 geos like Indonesia, Egypt, and Bangladesh, the volume is massive and CPMs stay very manageable. Worth bookmarking this page before your next campaign build.
