Google Alerts are notifications that selected search terms  are appearing on websites. For example, I have Ralston360 and 360View as Google Alerts. I receive weekly notification (you can choose your own timing) that these terms are appearing on other websites. This notification helps me to see when someone is ‘talking’ about my company. Good stuff.

If I am unclear here, here is Google’s definition: “Google Alerts are emails automatically sent to you when there are new Google results for your search terms.” You can learn more by going directly to Google Alerts.
