If you’re running pop traffic, keeping your blocklist fresh is important. You don’t have to update it daily, but waiting too long can waste your budget. Many affiliates check their sources weekly or after running a new campaign. Once you see a placement bringing fake clicks, zero conversions, or very short visit times, it’s better to block it right away. Some bad sources look good at first but later turn out to be useless. That’s why reviewing your data regularly helps. You don’t need a long blocklist to begin, just stay consistent with updates. What are your thoughts on keeping a clean blocklist when running pop traffic?
