Glossary term: Google Death Penalty
The complete, and potentially permanent, removal of a website from the Google index. This can happen for any of a number of techniques that run afoul of Google's guidelines, but the most common activities to cause a Google death penalty are cloaking, invisible text, and doorway pages.Most famously, the German website of BMW was removed from the Google index for the usage of doorway pages with redirects. Unlike most websites, they were able to be reinstated into the Google index after only one week.
