I think the hits are either (a) computer generated, or (b) generated by a group of people in Taiwan who are paid to click on the advertised links. Most of my online users are from the U.S, but to receive such a large number of visitors from Taiwan, eventhough I didn’t have any Taiwanese pages, casinos, or Taiwanese link or advertising partners is very suspicious. Also, 99% of my registered players are from the U.S. I don’t recall one being from Taiwan. Personally, I think you’re getting ripped off. Here’s what you can do… Set up a unique profile for that paid advertising traffic and send all those visitors to that profile. If you still receive 1000s of hits and no sales, then you’ll know what I mean.
For example
create a page and call it advertiser1.html
Set up a unique campaign and call it advertiser1
Send all this traffic to this page and see if you get any sales.
