I recently had my book promoted on www.integrativepractitioner.com, which has over 6000 members, and with one email campaign, my sales rank on Amazon went from around 500,000 overall to around 25,000! I'm told you're considered an Amazon best-seller if you can reach the top 100 in any category. Imagine if you combine 50 of these blog, email and promotional campaigns over a short time period, and I can see how any author can become an Amazon best-seller.
