Is my product idea viable based on these results? I've got an idea for an e-book so I set up a fairly crappy 1-page site and ran an AdWords campaign to test the market for the e-book. The users fill out name and address, then hit a 'continue purchase' button which then shows an error, so no cc info is actually taken. I consider this a "conversion" when it happens. My $39.99 e-book would be breaking even, i.e., just enough revenue to cover the AdWords campaign right now. On the one hand my product viability looks bad. On the other hand, with a real website, some AdWords optimization, and some SEO work, it seems like it would be doing a lot better. So my question: Is my e-book idea worth pursuing? (I realize it's hard to answer without a lot more background.) I won't into the product details but here are some of the AdWords numbers. Again, my cost per conversion is about equal to the cost of the AdWords. I'm getting about 3% CTR on my search campaign and 0.07% on my display campaign. Sample size is *really* small now-- 120 total click-throughs. My AdWords are pricey, about $1.30 apiece. I'm getting about 4 purchases for every 120 click-throughs. I'm a newbie so any comments appreciated.
