A lot of people come out strong then complain that their campaign died. It died because you let it die. Running banner ads on POF is not an auto pilot thing. IT's a daily GRIND. You must create new ones and delete bad ones DAILY.
Use this one not so secret tip and you will do far better on POF then you were.
I even go so far as to create a campaign for each day of the week. I run it for 24 hours, then pause it. Run the next one. Repeat that for 7 days then restart back at day one.
