Google Analytics is one of the popular tool to measure site traffic and now Google has now added a new feature to Analytics called Intelligence. With this new beta feature, you can create alerts for your analytics account. You can create daily, weekly and monthly alert. Analytics Intelligence constantly monitors your website’s traffic. Anytime something significant happens, it adds an automatic alert in your Intelligence reports. If your bounce rate suddenly jumps on one of your referrals, Analytics Intelligence creates an alert.
You can create an alert for variety of conditions like traffic, city, country, campaign, keywords etc and you can also set the condition when the alert is triggered. You can also apply an alert for multiple profiles. The alerts can be accessed from Intelligence menu on the sidebar.
