1. To monitor reputation — I have Google Alerts set up to send me a notification if an article is posted regarding my company or company name.
2. Industry News — I hate to be the last to know new news. So, I have a Google Alert set for new PPC articles. This ensures that I don't have to wait for someone else to "share" the article. And, I stay on top of the best of current PPC news!
How do you use Google Alerts?
