Wikipedia can be a tremendous asset to an online reputation. Wikipedia articles are almost always the first or second result in a search. They are known for being generally trustworthy and receive lots of search traffic.
Additionally, most investors and journalists begin their online research with reputable, neutral resources like Wikipedia. So having a Wikipedia page is crucial of you are noteworthy enough to get approved for one.
However, there is one concern I must raise at the outset. The number one rule in reputation management is that you try to control all the channels of everything said about you. A Wikipedia page opens you up to someone publishing unflattering material that might have been reported.
If this happens you need to have enough positive information to contest and bury it.
Make sure that you do enough preventative maintenance so that you need not worry about things that might not happen.
