I’ve been seeing a new trend for about the past 6 months or so. The trend is buying old domains with PR5, throwing up a copy of PHPLD with a free template, calling the directory a “strong PR5″ directory and charging for links. These directories are dead easy to spot, just look for the unusual name coupled with a lack of quality!
I don’t recommend you spend any money at all buying links at these directories. If they accept free listings, go ahead but don’t pay! Generally, the owners of these directories are just out to make a quick buck and will not spend any time or effort on building the traffic and popularity of the directory. We’ll see the evidence at the next PR update, but I am guessing most of these domains will lose some if not all of their PR and incoming links.
I am not saying putting directories on old domains is not a good thing to do, but like with any other directory or website, the owner has to work at it. I still believe there will come a time when a lot of directories will be dropped out of the index and only the unique, well promoted directories with added features for both users and submitters will survive.
So if you’re thinking of starting a directory, be prepared to put in some work. If you look at the top directories, their owners have put many hours into promoting and building a quality site. And the results pay off, becuase webmasters will pay to have their site listed there.
