Reverse SEO is the process of removing (technically de-ranking) websites other than your own from the first pages of Google.
Reverse SEO has become one of the most effective strategies for minimizing the impact of bad publicity within the search engines’ organic listings. It is an online reputation management (ORM) tool of SEO consultants who manage Online Reputation Management. Too often, companies become targets for negative press online.
Reverse SEO can be used to suppress negative publicity that targets your company in Google, Yahoo, and Bing. By pushing bad press onto the second, third, and fourth pages of Google, those pages will be prevented from gaining traction or attention.
