The best part is the price and its cost efficiency. The price of this tool is very low and hence it can be used even with small budgets. We have tried this tool for all the campaigns of our company and its performance is very good. I never faced any technical issues while using this tool on a daily basis. I have heard that its accuracy in terms of showing the exact click area on a page is not accurate enough. But other than that it works best for the whole. It has helped us track the traffic and page views and its also good to check the number of impressions. It also helps in reducing bounce and improving the CTR. I like that we can get an accurate picture of our customers' attention patterns in real time. The interface is very easy to use and it also provides great insights into how visitors interact with our website. It's also super helpful to have our analytics integrated with Google Analytics so that we can see both sets of data at once. Nothing really! We are using this tool to monitor our audience engagement and to optimize our website content.
