I have not seen them in my Google Analytics, but two days ago Google announced some powerful functions in their latest update to Google Analytics. Among the interesting new features is the Analytics Intelligence:
We’re launching the initial phase of an algorithmic driven Intelligence engine to Google Analytics. Analytics Intelligence will provide automatic alerts of significant changes in the data patterns of your site metrics and dimensions over daily, weekly and monthly periods. For instance, Intelligence could call out a 300% surge in visits from YouTube referrals last Tuesday or let you know bounce rates of visitors from Virginia dropped by 70% two weeks ago. Instead of you having to monitor reports and comb through data, Analytics Intelligence alerts you to the most significant information to pay attention to, saving you time and surfacing traffic insights that could affect your business. Now, you can spend your time actually taking action, instead of trying to figure out what needs to be done.”
