I have recently launched a couple of ads. The results have become a bit redundant. I have raised my budget per day to 100.00 and gone as low as 40.00 per day and I'm still yielding the same results??? My budget is always maxed out at the end of the day, and I get two sales a day every day no more no less. RARELY... I'm mean RARELY i yield three . The site is a retail home air filter site. I've also noticed geographically they have been close in proximity day by day? Has anyone had results that have been suspect?
