Make sure that you are doing what you have to do to make content about your company as positive as possible.
If after some time, things are not changing and you find that you cannot rid your company of negative online content, then it might be wise to consult with experts. There are a number of companies now whose sole business model involves defending online reputations. Investigate these companies thoroughly. This is an emerging industry business model. Find out what they can and cannot guarantee, and what costs they associate with the guarantees they make before you jump at what they offer.
