I have a domain name that is two years old, but I have only recently (past 4 months) begun to do anything with it. It is an e-commerce site with approximately 80,000 pages. I also have a few extra sites dedicated to specific categories. These sites then link back to the main site. I would appreciate it if someone could give me some general advice on how to get started. I would prefer to be more "safe" as opposed to more "aggressive." In general... what can I do? Would it be a bad idea for me to pay one of the XRumer services to blast my main domain with links, given that it is already two years old? What about my extra, outside sites? Would those better ok / better? Are there any PDF's / books / etc... that you would recommend that someone in my position go over? Thanks.
