I think the most attractive ad is the one which speaks about a product someone wants and at a very convenient price. So, maybe we should post TripleClicks products on different websites and when people want and/or purchase, they find out both about TripleClicks and SFI.
Also, we should not forget making this repeatedly, 5...6 times every day, both on one or two differents famous sites, and on less known sites, so that as many categories of people to notice them.
