Your first project as the new web designer at Smart Design is to increase web traffic to help boost web orders. Before you begin redesigning the website, you look at the website analytics. Why is this step important?

The correct answer is letter "D": It will let you know how the visitors are using the site and where there might be problems.  

Explanation:

Web traffic refers to the concurrency of users to a determined webpage. It reflects the amount of people surfing the web page at a given point in time but reports could also provide information about peak hours of use, most visited features of the site and average time spent. At the same time, web page traffic reports may record frequent errors of the site that could allow a web designer to have an idea of where improvement is needed.

Therefore, the new web designer at Smart Design should review the website analytics to spot problems of the site and solve them so the flow of purchasing orders can be executed faster.
