The website that you created either helps or harms your company or customer in all sorts of ways. Unfortunately, it can be really difficult to measure customer intent and gauge how well your website is performing unless you really talk to consumers about their experience. Also, it is good practice to get an overall user experience from the current web trends.
An online website feedback survey will be helpful in this case. From a developer's point of view, the PrimeFaces community forum (to have a look at this forum, visit http://forum.primefaces.org/viewforum.php?f=3) is also a good place to discuss how to create a better design. Users usually give feedback about what's missing in the design and what needs to be removed. Then, after receiving the feedback, you can redesign your website with the required theme changes according to customer requirements.
In this way, you can design a user interface that is commonly used and expected by many users.
