Move up the ladder, and you'll encounter a few paid services that can not only monitor your online reputation but also help you manage it more actively. Many of these offerings are targeted at very large companies with full-time ORM needs, but a few have options suitable for smaller concerns.
Reputation.com: On its site, Reputation.com claims that "it takes advanced (and patented) technology to 'make your good stuff go up and your bad stuff go down'" in the arena of search engine results, online reviews, and forum comments. If your line of work tends to attract cutthroat online-review activity--the company specializes in assisting medical doctors and the hospitality industry, for example--having an amalgamated way to keep your finger on the pulse of what's being said about you, in real time, might be worth the investment. Business monitoring starts at $49 a month, and "Monitor + Control," which remediates negative material online, is priced based on how much damage control needs to be done. The company says that the typical small business pays about $1000 per year. (Full disclosure: The author's brother is a Reputation.com employee.)
Trackur: This pricey service--depending on options, fees range from $18 to $377 per month (and more, for managed monitoring)--performs deep dives into the Web, turning up mentions in news stories, in forum discussions, and on social media. The results appear in tabular form, and are accessible via a dashboard that tracks the mood of conversations directed at your business. In my experimentation with the system, it marked all stories uncovered as "neutral" in sentiment. The company does not offer services to help remove negative material.
