Here’s a free tool that can help you in understanding what users click on your webpage. ClickHeat is a visual heatmap of clicks on a HTML page, showing hot and cold click zones. And since it’s free, you get to host it on your own server and keep all of the recorded data.
Included features are:
– Low logging activity: a very few function calls to log a click, no server load rise should be noticed (have a look at Performance & optimization)
– Screen sizes and browsers are logged, making possible the tracking of liquid CSS layouts (100% used width).
Tips: Sounds good to be used with split testing your landing pages.
