Blog profits

Just had an idea on how to improve traffic to my free e-book blog @ http://makeclickbanksales.blogspot.com
visit money making forums with visitors that are looking for reviews on the products I am offering free downloads on and basically give them the link to my blog, sounds simple but more hits hopefully offers more adsense income.
I'm very interested in adsense as a lot of "gurus" say they can gain $100 cheques monthly from adsense on blogs and I've made only $2.99 from March '09 to September '09, very poor. The problem I have though is that I've only used it on sales pages which can detract from sales on that particular site and at best make you $1 adsense income. 1st rule of sales pages...do NOTHING that will take visitors away from your site. Offer NOTHING to distract them from making a purchase.
Anyway I'm hoping to get my blogs ultra popular, which I believe they should be as they offer something I haven't seen elsewhere, which is unbiased, non-sales related advice. When my blog is ultra popular they should generate adsense profits without detracting from sales on my other sales pages.
