By now you should have a good idea of what Virtual Real Estate is and why it's to your benefit that you start a network of your own VRE sites depending on the model you choose.

In the last installment of this series I covered "Article Directories".

In this part of the VRE series I'm going to cover "Web Directories" in general and then give you some examples of what they might be and look like.

An "Web Directory" is simply a directory on the World Wide Web that specializes in linking to other web sites and categorizing those links. For more detail go to: www.googleincomemachine.com. Web Directory owners will often allow site owners to submit their site for inclusion. Then human editors will review their submission and if accepted, will be added to their database.

The one thing about Web Directories is they are often used as part of a website marketing strategy for being indexed in the major search engines like Yahoo!, Google, MSN to name a few.

The main strategy behind someone submitting there website to a directory is that a new site needs to quickly build inbound links from reputable sources. In doing this they will get a higher ranking within search engine results under there target keywords depending on the PR(popularity ranking) of that directory or inbound link.

That's the basic run-down of what an Web Directories purpose is and why they make a great VRE business model.

Web Directories can be and target anything you want them to. It's your directory, so you make the decision as to what it is about.

So, with that said, here are 3 directories that I think will give you a good idea of what to expect:

Also, pay special attention to where those Google Adsense ads are positioned because this is KEY to getting a good CTR(Click Through Rate) with your Google Adsense ads.

Now, at this point, it's up to you to make the decision on whether or not this is the type of VRE business model you want to use and start.
