Perhaps so but I had decent conversion rates for the day right up to a couple of hours ago - just went 2k clicks without a single conversion.I find Monday-Thursday's better days. Typically, on the Friday's and weekends, you have many college students ready to go out and don't have time to go through the while IQ test. They will practically jump out of their apartment at the sound of their cell phone. So try running the campaign on other days, it should at least convert a little better.
And now the conversions are starting to come again. Something was definitely wrong.
