Just give it some time. To get more traffic you may want to write and submit articles to the popular article directories, and if you are in a niche that would be good for list building you should be collecting names and email addresses and do some follow up marketing with these individuals with an autoresponder service. When I started list building I increased my profits a lot. Just my opinion
Got my first sale! $20 in the bank!! Took me 240 clicks to a selection of ebooks from 10,399 visits to my site but I'm finally off the mark.
Yeah, its a nice little earner. If I could do 10 a month I would be overjoyed. Might do a few reviews on the site on the ebook instead of just text links in the side bar.
