I’ve also had poor conversions with overture uk. With the quality of the traffic the most I would pay is 50 cents a click. From what I can tell the traffic is as fraudulent as the next PPC.
Back in the day gamblehouse and casinoprophet would pay upwards of $40 a click on overture USA. It’s rumored that they had kickbacks. The reason for this is it would drive the price up for everyone else.
I’m assuming something similar is happening at overture uk.
Then again, if they get high rollers here and there it might warrant spending that much.
