ClickTale is, I would say, a brand-new applied tool; its founder is Tal Schwartz. It is said that this tool can increase the view rate of your blog and your advertising revenue (similar to Crazy Egg). Because it has an automatic tracking function that allows you to easily understand how your readers are reading your blog and see how their mouse moves. However, it is currently still in the beta stage, the company is conducting an online survey. I speculate that there will be a short period where it's free at first, but then they will start charging. This is an inevitable process for an authoritative product to grow. Moreover, it is unknown whether it can support Chinese blogs. We need to keep tracking it.
