As the SEO Ninjas reported yesterday Google have been penalising websites all over the Internet in terms of their visible PageRank. Some sites have been hit as hard as dropping from a PR10 to a PR6. Perennial Google victim John Chow, who due to a previous Google punishment doesn’t even rank for his own name, has dropped from a PR6 to a PR4.
The popular theories for these punishments range from selling paid links to simply removing Google’s Adsense (not much chance of me doing that ;)). It must be said though that even with PageRank penalties such as these it shouldn’t effect your SERPs at all.
The fact that MrDaz.com is unaffected is actually slightly offensive. Why haven’t I been penalised? Ah well, never mind.
