A HighRankings Forum thread asks how does one distinguish between a good and bad web directory. Web directories are often the first step for many link building campaigns. The obvious directories that come to mind to submit to are dmoz.org and Yahoo’s directory. But many people like Best of the Web as well.

The question is, how does an SEO or webmaster know which directories are quality and which are not. This gets more important when you are submitting to niche directories.

Here are just some points, off the top of my head, to look for when evaluating a directory.

Age of directoryIs the directory indexedIs your listing category in the directory indexedNumber of links to the directoryDomain age of directoryDoes directory require a link backPageRank of directory’s home pagePageRank of the category of your listing in your directoryDesign of directoryHow large is the directory

Again, these are just the things that came to my mind as I wrote this post. If you have more to add, please do.
