“From what it looks like, the German websites of car maker BMW have been kicked out of the Google index. BMW.de at this time has a PageRank of 0. A search for BMW Germany, which only days ago yielded BMW.de as a top result, now doesn’t show any sign of BMW.de at all. Instead, BMW.com — BMW’s international site — is on top for this search. The reason for the ban is likely to be that the BMW websites have been caught employing a technique used by black-hat search engine optimizers: doorway pages. German and international bloggers last week were quick to spread the news.”
