I recently posted a long and detailed article about the importance of heat-maps for improving user experience.
I used the tool called CrazyEgg to get the heat map for this blog. This is a detailed review of the features and pricing of CrazyEgg heatmap tool.
CrazyEgg provides a 30 day free trial of their service and to activate it you would need a working international credit card. They will check if the credit card is active and they will start your trial.
You will not be charged anything upfront. But if you do not cancel your account, your recurring billing will be $108 a year or $9 a month effectively. In the basic plan you will be able to track and get data for 10 different pages.
