Google offers a great FREE service called Google Alerts.
Google Alert is an automated Web search service that can help people and businesses monitor the Internet for developments and activities that could concern them. Results are sent to subscribers daily by e-mail.
Google Alert can, for example, track new online appearances of a person’s name, a business name, or a particular Uniform Resource Locator (URL). Add www.sofiblog.com and www.mortgagehorror.com to your Google Alerts.
Individuals can use the service to monitor what is said about them on the Web. Businesses have found the service useful for keeping informed about blogs, markets and competition.
