If you exchange your time for web traffic you should work only on sites that constantly produce results. Overwise you'll waste your time which is the most valuable resource.
By results, we mean signups and sales. After all, it is what we expect when posting our ads.
I published the most recent list of best converting sites on my blog. Read that list and see if you are missing out on any of these great traffic sources. Spend your time only on sites that are proven to convert.
Thanks.
