This is the worst Christmas present possible. Well, Google had no choice and the apology was not a stellar one (not that it could have mattered).
If I recall correctly, Google once penalized Google Chrome for doing shady SEO [1]. Although it was not as brutal as this which sends them to the equivalent of Siberia.
My Questions.
1. I normally search "<song name> rapgenius". Now, it is no longer on the first few pages. Is that not against Google's goal of giving the searcher what (s)he wants?
2. Probably the only way for RapGenius to counter this would be to go heavy on AdWords. Is that not a bit conflicted on Google's side?
Hopefully this punishment will not be permanent. I would hope they have learned to tone things down sometimes.
This may be a lesson in disguise as they would be forced to think of how to survive without SEO. If they can survive now, they will be doubly badass when this penalty is lifted.
