Google Alerts is a great way to keep track of what is going on online. If you have a Gmail account you can set up an alert for a specific term and Google will email you when that term is posted on the internet. You can set it up to email you immediately or less often.
You can manage your alerts and change their settings or even delete them.
This is what the alert email looks like. It puts the key term in bold so you can see how it is used in context.
Why would you want to set up an alert? If you are like me, you want to know when you are being discussed on the internet. Another great way to use it is to see if someone is talking about your blog, wiki, podcast or other content you have created and posted online.
I love to use it to see who is posting about a pet project of mine: #comments4kids.
