People who are complaining about not getting any traffic after using software like Boomarking Demon or Social Bot...maybe your websites aren't what people want to see? If you don't have an a good looking or interesting site, of course you won't get any good traffic. That's not the softwares fault.
Also if your backlinks aren't being indexed by Google or the other search engines, you won't see any improvements on your link quantity and therefore, no improvements in traffic.
You need to make sure the pages you are submitting your links to are being pinged. I believe SEO Nuke does this but I can't justify the high subscription fee. For that kind of money, you could just hire an outsourcer to do all this work manually which if you find the right person (and I emphasize the word if), is a much better option.
Problem with us all is we look for the easy solution to all these time consuming tasks involved with SEO and marketing, and then become disillusioned when these solutions don't produce the results we expect. I believe some of these software solutions over promise to draw in customers which is a shame.
Bottom line is for me... all this works takes time. You can either do it yourself or pay someone else to do it for you. Catch 22.
