A hero header on the page refers to the large header that grabs the attention at the top of the webpage. It is also called the hero banner and is often featured with compelling images and nice introductory content. Some websites may also use videos and other representations to put out the key message, a tagline, and even a call to action.
Hero headers are important in creating the first impression, and this can make or break the engagement with the user. Its main goal is to hook the user on what the website sells and engage with them until they perform a desired action.
