If you believe an article about you, your client or employer is unfair, the first step is to stay calm and keep a cool head. The more impeccable your conduct is, the easier it will be to get the problem fixed. Don't just remove it, but start engaging editors on the Talk page of the article. A few things to keep in mind include:
- Is the company's viewpoint represented? Wikipedia's "Neutral Point of View" policy dictates that all viewpoints be represented fairly. In most cases, this means including the company's perspective, as well as opposing viewpoints.
- Does the controversy consume most of the article? The only practical way to balance an article that only covers controversies is to research, write and code the rest of the article and offer it for consideration by the site's editors.
- Does the content follow the rules? If the critical or controversial content only uses primary sources, such as court records and press releases, and there are no independent, secondary sources (like press articles) that cover it, you may safely ask an editor to simply remove it.
- Is the content bias or are you? Thoughtfully consider whether the Wikipedia page is actually bias. Wikipedia just regurgitates information found in credible sources like the media. An article is typically bias only if it is not representative of the available independent body of literature.
- Are the editors being reasonable? Some editors may be inexperienced, bias, have an axe to grind or a strong point-of-view on the subject. If you feel that's the case, consider involving more editors by advertising your request for discussion at a relevant WikiProject or the Conflict of Interest Noticeboard.
