Everything in Clicky is up-to-the-minute real time. Not just a few things (*cough* Google Analytics). Everything.
Most reports provide a high level of detail on every segment of visitors. You can filter and sort by any column to quickly find what's working and what needs improvement.
Individual visitors and actions
Clicky lets you see every visitor and every action they take on your web site, with the option to attach custom data to visitors, such as usernames or email addresses. Analyze each visitor individually and see their full history.
In addition to standard per-page heatmaps, Clicky also lets you view heatmaps for individual visitor sessions, including segmentation. For example, you can view heatmaps only for visitors who completed a specific goal. Heatmap data is real time.
You (and only you) will see the on-site analytics widget in the corner of your web site. See you how many total visitors are on your site and how many are on the page you're currently viewing, with the ability to view those visitors right from the widget. Heatmaps and heatmap segmentation can be launched from the widget as well.
Clicky alerts you when your site goes offline so you can react immediately. Your site's uptime is monitored from 5 geographic locations around the world and alerts are only sent when a majority of the monitoring servers agree that your site is down.
