I have seen few directories with zero links/content having page rank. Is this possible that we can achieve page rank with out any content?
well I think PR is not entirely on content-depending, it has other factors to consider such as quality and number of backlinks
May not be faked, these directories may be setup of existing domain names that had just expired but their PR remained intact. I guess for most of such directories, their PR will return to zero unless they really work hard on keeping the existing links.
wisdomtool hit the nail on the head. Domains with pr, that show no backlinks, are most likely either dropped domains or domains picked up in auction. There are many directories being launched these days with dropped domains, so what the OP notes is actually quite typical.
You can find many parked domains having PR. So you know how good google's PR is Expired domains and redirection are the well known methods. I wonder if there are more such methods to get PR without backlinks/content.
As others have mentioned, page rank has nothing to do with content- it has to do with the backlinks that a domain has. It is possible for a directory to have page rank and no content/links at all. All the directory would need to do is simply buy a bunch of backlinks and/or submit their site to a couple hundred junk directories and most likely in about 6 months after doing this the directory will attain some page rank.
Very strange that I also have some directories that gain PR but not have contents. It recieved PR from high PR sites that link to.
I think the real question one should ask is "If you have doubts about the quality of the PR the directory has (especially when it has zero or little backlinks), why deal with the directory?". I usually stay away from them as I have personally monitored one new directory with high ranking PR having its PR drop during the PR exercise and many people paid good money to get listed when it was at the high ranking PR. Ouch!
I don't understand why to create new directories. Today directories seems to have very low importance. ;-)
