I would think it would be less valuable to pay for traffic with the intention of a sale only to direct them to your page about the sale which directs them to a sales page of the product.

It seems redundant even, unless of course you have some hardcore know-how and your review is really on par. But, that would mean your advertisement would have to be very specific.

If I click an ad that claims this product can cure nipple aches or whatever, only to find myself on a page with a review of a product. I might just hit my back button and go to the next entry.

I guess it would be interesting to see some cross-testing.

Good Post, I’m actually in the process of trying a cross-testing. Using two different products however that focus on keywords that generate roughly the same numbers. Though I’m not using PPC at all, just free targeted traffic.
