I have a competitor who always ranks very on alot keywords relevant to our business and using Open Site Explorer I note they have a tremendous amount of links. I also noticed that it appears their web company has gone out and set up numerous websites with relevant content, and then have linked back to the competitors main site. Is this kosher? I ask because before I settled on my current domain name, I purchased several keyword rich domain names; should I be thinking of setting up websites with relevant (and original) content and link back to my main site?
