Whether favorable or not, web pages, articles, and blogs can’t be removed from the web by anyone other than the site owner — although they can be demoted so they are less readily found. (Legal action or request for removal can be considered, though might ultimately draw more attention to the problem.)
Rather than focusing on the negative, we work with clients to build a deliberate online reputation, which includes a variety of different content types and media (owned, earned, paid, and community). At the same time, we continually measure how our reputation building efforts are impacting the client’s stated goals.
