Parasites: I consider parasites to be Facebook, YouTube, LinkedIn and soup.io and I occasionally use Amazon (as I hastily wrote a small ebook for my niche so I could use a product page legit) and I know there are more but these are the only ones I use.
Web2.0: I only use Wordpress, Typepad, Jimdo, about.me, webs.com and blog.com - I never use blogger.
This is how I do it (not saying it's perfect but it works for me)...
I create 6-10 web2.0's/parasite pages to my money site. Some of these I have had for a couple of years but there are a few that I have only created in the last few months. I use different identities and different email addresses (and I use HMA - hide my ass) whenever I create these identities. I always do an about us page and each one has a couple of posts BUT I always link out to authority sites as well such as newspapers and other media sites.
I then create 2 web2.0s/parasites to each web property in tier 1, again using different web identities and do the same process as above.
I then use GSA to send links to these tier 2 properties BUT on my latest run, I only sent links to a couple of the tier 2's but also tried a Magic Submitter campaign aimed at the rest of these tier 2's.
My rankings are pretty good - I'm in the top 3 for my main keyword which gets about 20,000 searches a month. It may not seem a lot but the income for this type of business is very lucrative. I should also point out that my main money site was launched in February 2008 and has almost 3,000 pages indexed in G.
