In my search for a good advertising network I came across clicksor.com. I created an advertiser account and set up my campaign and deposited $20.
My campaign was approved within a day and a Clicksor support staff called Sylvia sent me an email telling me that my campaign was approved.
About 30 minutes after I received this email something really weird happened, I was looking at my Google Analytics account on the website's real time statistics (where it shows the visitors currently on the site live) and I noticed that from zero visitors it went to 45 in a minute! I thought great! This is awesome, of course it didn't last long, about 5-7 seconds later ALL the visitors were gone, no exceptions!
I logged in to my Clicksor account and guess what, $20 gone. Just like that!
I switched to Analytics again and I saw that 45 visitors from Clicksor came to the site the exact same minute and ALL of them stayed exactly 5 seconds, 100% bounce rate.
Let me just clarify that I use many other advertising venues for the website and the average visit time of the last 2 weeks was 2 minutes and bounce rate in 60%.
I replied to the Clicksor support staff, Sylvia, asking her what's going on, a day passed, then two, then three... No reply. I created a new support ticket and waiting for 2 days, up to this point, I didn't receive an explanation from Clicksor and will be filling a complain on PayPal for a refund, I will post the results from PayPal here.
The bottom line is that I will not suggest to anyone to try Clicksor. The support didn't even make an effort to justify the situation. $20 were going in 10 seconds and all visitors were bots, stay away.
Sorry for the long post
