Let me expand a little on the over all picture...

This is the same as creating old fashioned doorway pages. The difference is, instead of hosting them all on one domain, we want to put a page or two in as many different places as we can.

This concept is also exactly the same as "spinning articles" and submitting them to various directories. Difference is we are "submitting" them to places where we have control over the articles and all the benfits.

Submitting articles is also another linking method that can use "spun" material, I just feel it is better to spend a majority of your time building your own network. You don't need to get each article "approved" and you have more control over the page than you do with submitted articles.

Another old school SEO term is "hallway page". They were kind of like site maps, their only purpose was to have links to OTHER pages, doorway pages, to get them indexed.

In other words, "hallway pages" are used to lead the search engines to the "doorway" pages.

We want to consider this concept with our network, especially tin sites. Every page you create can easily link to 5-15 of your other resources. Use your tin sites as "hallway" pages. Use your articles and content as a means to get links to all your other sites.

This includes any page that links to you. If you have a page that's been Dugg, link to the page on digg.com. Same with your social bookmarks. Same with directories, screen saver sites, any decent page that links to you, you want to try to include.

You want to continually point links to other pages that point links to your other pages...And on and on...

You want the engines to constantly find links to your stuff and it's up to you to make sure that once they find one page in your network, the spiders will find more and more and more links all pointing to more pages with more links.

Try to mix in a good amount of high quality links to sites you don't own along with your own links. It can't hurt to put your links "next to" sites that have a lot of respect.

Pick your major niche and find the few major sites your probably can't compete against any way...The kind that has a million links or more. This will give your sites more respect and your links to them won't make any difference since they already have so many.

Quickly:
Put as many words on as many pages as possible.
Use these pages to link to more pages.
Mix in links to highly respected sites with your own.
