Many newbies attempt to get free traffic as quickly as possible. So they link to everyone and anyone who will link to them - including link farms and traffic exchange programs. This is a mistake. These types of websites provide zero end-user benefit - just a bunch of worthless links. I call these types of sites "garbage websites," because the quality of traffic they send you will be just that - garbage! The only links you should attempt to obtain are quality, relevant links - period. Links that are compatible to the overall theme of your site. That's what the search engines judge you on. For instance, if you sell hosting services, a link from a site that sells real estate is of no value to you whatsoever. It just isn't. See my point? Speaking of search engines, make no mistake, Google, Yahoo, and MSN pay close attention to who you're linking to and who's linking to you. In fact, when it comes to PageRank, Google places more weight on link quality and relevance than to the actual link itself. So go ahead and link. Just do so responsibly! Dale King
Yes but even the worse link is better than any and what is the puropse to make copies of DMOZ and wikipedia? I guess that they are destined to be farm links and their owners take into consideration probability of google ban. If that happens they lose one of the copies and put another.
