am I the only one that this happened to?

i tried a few adwords campaigns, and i thought i did exceptionally well at picking my keywords, they were as targeted as I think they could be, but that's beside the point. the ads i thought were good too.

I had the the ad then linked to my website that redirected them to the clickbank page, and i know im not supposed to do that, but i wanted to see if just a little money could be made.. and no money was made.

i was getting good click thru ratios and all, but no one was buying or signing up.. i tried this with several products and campaigns..

im at a loss for an explanation. i just reverted back to articles, adsense and blogs, but i still want to exploit adwords.. i dont want to be a quiter...
