I have a social bookmarking site http://slurke.com which receives an average of 1000 UVs a day. I was earning around $2 since last month. But for the last 2 days though traffic has increased i don't find any clicks and the same ads are displayed on my site. What could be the reason? Is it due to crawler error problem?
you have to change ads placement right to left and if you have on top then put under contents and after few day change place again.
