For the longest time, I have been averaging about $.79 cents per click. For the past week, I have dropped all the way down to an average of $.38 cents per click. Why is this? Anyone else experiencing this?! Will it go back to normal?!
The PPC depends on the number of visitors on your site, or the traffic in better term. May be your traffice has dropped a bit to make it low on click. However, there may be some other problem also, you should wait for some more time to check it and then react.
