It is difficult to compare Wikipedia to any other domain because everyone believes there is a different set of rules for Wikipedia but let's say for the moment that isn't true.
What evidence would there be to suggest that Wikipedia is not whitelisted? All the evidence I have seen suggests otherwise. If most websites used the heavy interlinking strategy that Wikipedia employs, this would be deemed over-optimization. Wikipedia is non-commercial and poses no threat and/or lost income opportunity for Google. I've seen a number of "case studies" before on some less than desirable forums where blasted spam links were pointed at Wikipedia, .Govs and .Coms. Wikipedia has never budged in these supposed case studies, while .Govs fall a bit and commercial .Coms disappeared.
Today it is going to be warm, and the kids would sure like to go for a swim. So I search for a swimming pool. Wikipedia sits at #2. Do people really need a definition for a swimming pool or is just used as filler material to make all of those paid ads look more appealing? There definitely is no shortage of paid ads in Google these days. :)
hmmm... you mean it puts DIYSEO out of business don't you?
Not at all. They just need to follow what the big boys are doing. That is buy links in bulk and have the capability to remove them in 24 hours when caught so their penalties are revoked in a week or two. I can't tell you how many small business websites we do design work for that have corporate competitors that not only have internal SEO departments that buy a lot of links, but also build complete non-competitive websites just for the links. But how well will this strategy work for small businesses anyway when Google's algorithm favors corporate brand over any other signal? I suspect being the first small business website at the bottom of page one or top of page two may have some value, but not enough to be worth the effort to attain it.
