Sritharan, In order to investigate your Unique Visitors for your website, there are Analytical tools such as Google Analytics. Not only the GA, but there are also tools available to track all the traffic-related metrics. I prefer the GA tool.
To identify your unique visits, You need to have a Google Analytics tool and follow the below steps.
- Open Google Analytics
- Click on Audience from the left-hand side menu
- Choose Overview
- Set the date range from when till when you want the data
