With eBay rumored to buy StumbleUpon and Google announcing plans to develop a StumbleUpon competitor, the need for “real-time analytics” has skyrocketed. The main thing about these services, and services like Digg, is that they cause sudden traffic spikes, instead of the evenly distributed swell that Google index inclusion creates. As such, there are important hosting and social networking elements to consider. First, you must be able to sustain maybe 100,000 visits in a single day. Second, you must be able to identify when such surges are occurring and take action on THE SAME DAY to leverage the new traffic. Do you have a call-to-action on that page? Is all the traffic bouncing? For these reasons and more, you need HitTail, and the ability to watch your referrer traffic in real-time. Watch the Digg Effect, the StumbleUpon Effect, and soon, the Google Effect, in real-time.
