We're doing some reputation management for a client, where we're trying to push an unfavorable search result off the front page of Google. The problem is that the unfavorable search result is from a site with only five links to that particular page, yet the result refuses to budge because it's ranking high due to the power of its domain. We've built loads of social media profiles, links to our client's sites, etc, but the page in question won't get off the first page.

Do any of you have any suggestions or tips on anything else we can try?
