When creating a website, we track all previously defined goals. We may want to inform, sell or just build our email list. We then think about it, arrange the content purposefully and maybe try with A / B tests, which is better accepted by the users. But that can cost a lot of time and is actually more of a tool for fine adjustment. In the beginning, the question should rather be how users perceive and use our website.
Bing, the search engine from Microsoft, has now released an open source tool that will help. With Clarity a replay session is made, so to speak, with which one can follow the user behavior. A heatmap is used, but also a scrollmap is included and mouse movements, clicks, etc. can be tracked in individual user sessions. So website operators can understand exactly how the website is used and where problems may occur, or which areas are not even looked at. With this knowledge, the website can then be adapted to the needs of the user.
As a small but nice extra, Clarity also makes it easy to see if you have become a victim of malware, because the sessions display the content that the user sees. If something else is displayed here than your own website, you can react quickly.
