This brings us to the key issue of ethical SEO. Search engine optimization is still a very new concept to most companies. Even the most respected companies can make mistakes in this arena, either by choosing the wrong SEO service, or by trying to avoid hiring an SEO service altogether by bringing it in house with well-intentioned but unqualified people. For example, BMW's German site was recently removed temporarily from the Google index for using doorway pages--something that is not considered an ethical SEO practice. It stands to reason that your competitors are also not immune to violations.
