Mind if I ask what your FB test was like? Most people who "test" on FB don't wait till results are statistically significant, particularly with conversion data.

Mind if I ask what your FB test was like? Most people who "test" on FB don't wait till results are statistically significant, particularly with conversion data. Beyond that, you typically need to test at a loss initially, get data, and then optimize to profitability as you dial in your targeting and test new creative (which you absolutely need to do given how quickly banner blindness sets in on FB). Also, have you tried paid search? And if you don't already have one I'd consider an affiliate program. Gives bloggers another incentive to write about you, and you have a very "PR-friendly" business concept.
