Or is it a very high SEO single domain where it is loaded with Google juice / banner ads?
I keep reading different variations and out of all the lists out there this one should give the facts.
Take care and kind of glad it is a paid site as it keeps the not so serious away
The way to great rankings is to have a great website. Fill it full of great content that is useful and interesting to readers. If it doesn't have that, then it doesn't deserve to rank well anyway.
I think most webmasters would make better use of their time by improving their sites then trying to figure out how to get them to rank well. Because if they improved their sites then the rankings would follow naturally.
Here's a sample mention in Google Answers:
These pages look very much like the result of a "link farm". Google
has been programmed to "Zero-rank" (essentially blacklist) websites
that participate in link farms.
Search engines can often detect link farms -- look up the Stanford paper on "Combating Web Spam with TrustRank" for just one method they may use to identify the spammy links.
