Creating Positive Pages to rank above the unwanted indexed pages/negative press.
Press Releases/Articles with reputed profiles.
Web 2.0 Submission (very helpful)
Requesting the removal of pages from webmasters.
ORM is a strategic approach and the strategy always depends on the the current search results, keyword(Search Term), Search Engine(google.com, google.co.uk, google.ca etc) negative links and the positive links.
So without checking the search results and keyword its very difficult to tell you the exact effective work plan. I request you to please send me all details before working on it!
