You are right and it is not in theory only. All those money making gurus are doing it though not many will reveal it, they have more than 100s of these niche sites. Imagine just making 50 backs per blog. The sum is really quite substancial.

I’ll be happy if I can maintain 20 such blogs. LOL.

I have recently managed to take over a couple of abandoned blogspot blogs, and after getting my daily post for Karlonia out of the way, spent some time doing keyword research for them and posted one original “anchor article” so that the content could begin to be indexed. Having never worked with the Blogger platform before (my main site uses WordPress), I found it surprisingly easy and also had the opportunity to install AdSense blocks for the first time.

I’m not really sure about the actual income potential of these little sites, but since there are no hosting expenses involved with maintaining them, I figured that it couldn’t hurt to post some content, aim a few backlinks at them, and see what happens. According to what I have read at other blogs and forums, if I let them “marinate” for a few months and gain some positive PageRank from Google, they can be used for private sales of text links in addition to whatever AdSense income they may generate. Theoretically, if this process can be repeated enough times with additional sites, this will add up to substantial revenue over the long term.
