That is certainly eye opening and it's really amazing news. Hopefully in future the rankings could be fairly decided on usefulness and merit than who can buy or trick the most links.
Anyway so how would you explain the rankings of sites in this article? I thought all that was going for these guys were just the insane amount of links pointing to their site.
Interesting, but this does not seem to match empirical evidence by the likes of Ahrefs, which suggests that links are by far the most important ranking factor.
