Don't know what auto-generated traffic is? I'll tell you : it's like those
websites where they use credits systems to encourage you to visit other people's blogs/websites that are linked to them so that you can earn more credits and use them to get other people to visit you back. There was once a Nuffnanger (if you don't know what a Nuffnanger is, just take it as a blogger.) posted something about this great way to generate traffic to your blog for FREE!!
