Its always good as a rule of thumb if you are making bank, and i mean MAKING BANK, to mix in traffic to somewhat water down conversion rates, because when I get the dreaded "where do you get your traffic from?" phonecall, I can tell them that I took the offer url directly and hyperlinked it in some articles and some text on my blog, as well as mixed it up with some traffic sources, which would explain my high conversion rate and not make me look suspicious. By having a nicely ranked site in alexa, the amount of clickthroughs you get on hyperlinked text will seem plausible to your AM and, voila, no banned account.
