While there are companies that offer paid subscriptions to monitor your reputation on the internet, there are some free sites as well. One site that EXEControl Global Solutions is using is Google and their Google Alerts: http://www.google.com/alerts. This free service will allow you to type in key words you want Google to alert you of when website postings of the words are made. Other sites include: SocialMention http://socialmention.com/alerts for when key words are posted on social media sites, TweetDeck http://www.tweetdeck.com for when key words are posted on twitter and Technorati http://technorati.com for when key words are posted on blog sites.
Let the rest of us know if there are any other sites (both free and paid) that your company is using and what you think of the quality of their service.
