I tried 2 methods to increase traffic and sales on my website.

I tryed Google adSense for advertising my website, but I was not very happy with the results I got.

I googled 'opt-in email advertising' and tested each week the companies I found there (used the first ones listed on that page).and got a lot of traffic, but the sales did not increase too much. Acceptable results I got for taketheinternetback.com because it delivered quite good results in terms of generated visits and conversion.
