The most common issue that may cause the campaign to not run or run too slow, is a bid set too low. If your campaign doesn’t start or you receive very little traffic, try increasing the bid and see if this helps. TFPro is based on a real-time bidding system so if many other users target similar goals, you may need to increase the bid to get access to more visitors. It’s a good strategy to start with a small bid and then increase it slowly until you reach the desired number of visitors each day. Immediately starting with a high bid could mean that you end up paying more than you need.
