You can visualize real time data in Google Analytics. Google Analytics Real-Time is a set of new reports that show what’s happening on your site as it happens.
Measuring social media impact
Example: one way to use these reports is to measure the immediate impact of social media. When a new blog post is published and a tweet, with Real-Time it is possible to see the immediate impact in the site traffic.
Another way to use Real-Time is to make sure campaign tracking is correctly implemented before launching a campaign. When getting ready to launch a new campaign it’s critical to make sure your measurement plan is working before you start driving visitors to the page. With the Real-Time reports you can find out in seconds whether you’re getting the data you want in Google Analytics.
