Here's the deal:

Assuming that you want to fly under the radar, you'll want to make your traffic look as "real" as possible. Normally a site will have a ton of impressions (banner views) then a few of those will click through, then some of those clicks will convert. If your traffic swarm traffic is hitting the affiliate link directly, this counts as a click. If you're running a banner creative and you have a ton of clicks and very few impressions, this may or may not look suspicious. That really depends on the merchant representative and what he's looking for and how competent he is.

If you're running a text link creative, then they won't be expecting impressions anyway, just clicks. However in this case, when they look at the referrer it will still presumably show trafficstorm, which again may or may not look suspicious.

Basically, the result of all of this is dependent upon the merchant's rep at the other end of the CJ deal. Some of them are completely incompetent. A couple of years back I threw some incentive traffic at an offer and did 12k over the course of 6 months before the guy realized the leads weren't backing out and he decided to close the relationship on cj. He still paid all the commissions though, even after he closed our relationship. This can easily work the other way though, CJ is just a middle man and the merchant can reverse your commissions for any reason or for no reason whatsoever.

In summary, if you're running a banner creative you'll want a ton of impressions, a few clicks, with some of those clicks turning in to leads. You do NOT want 100 impressions, 2000 clicks, and 1500 leads.
