This video goes over the basics of WordPress MU and how you can use it to produce a large number of websites that attract visitors.

The developer shows the basic administration panels in WordPress MU that allows you to add new blogs and manage all of your sites from a single Dashboard.

Using WordPress for this reason is up to you. You could just use it to manage a number of different sites or you can gather together content for the specific reason of making money.

The video host notes the use of Google Adsence which is really one of the best features for all websites. Google ads can be targeted and limited specifically by you for your site or you can allow google to read your page and then pick an ad that matches.

The video also states that you can purchase content for reposting.

This is really not necessary and is probably not something you really want to do. If you can write a page in 10 minutes by keeping your WordPress Browser open while you visit other sites and then build your own content this is probably best. If you repost content you buy then you know there are other people doing the same thing and your visitors searches will be split across all of the people that bought that content.

So take a little time an personalize your site that way people come back.

Anyway for a preview of WordPress MU
