An interactive, smooth and easy to access website can hold audience longer than a complicated code stuffed non creative website.
For every website good numbers of customer traffic is the main object and each minute visitors stay on the website counts,
it means the longer visitors stay the more it causes good rank for the website. Basically the main reason behind the huge demand for a web designer over a web developer,
ignoring the fact that the first one can be a non technical person, is to keep the front end design eye catchy and easily accessible.
