Ask HN: Anyone have experience with Trada.com?

I used Trada on a partner's project for several months in summer 2010 (for a self-help product sold online). Since then Trada have improved their platform but I haven't tried it again. Our budget was $3000/month (the minimum required to establish a Trada campaign). We'd had a successful PPC campaign before using Trada and were hoping to improve sales volume and efficiencies. After six weeks, we halted the Trada campaign because we were burning through our budget. Our unit sales increased 1.5x but our costs increased 2.5x. We found that the Trada "optimizers" were incentivized to maximize traffic but not cost-per-action. Our Trada rep told us that if we stuck with it, our CPA would improve and incentives would shift to a CPA-based reward system. But we were losing so much money on each sale with the increased PPC expense we had to halt the campaign. Trada is legit and we were treated well by our rep and the optimizers. I learned some things about how to improve a PPC campaign. But the operation that was in place when they launched last year was not optimal for our small "mom and pop" ecommerce business. It was better suited for a large online agency or consumer brand business that could spend $10,000 and recover the upfront learning costs in improved sales over six or more months. Again, they have changed their platform in the last few months so maybe it works better now for businesses like mine. But expect to drop a lot of coin before seeing results.
