Web traffic can be defined as the volume of data that is transferred to and fro by the visitor for a particular web site. It is measured on the basis of number of visitors and number of pages they visit. Any web traffic tool will consider the incoming as well as outgoing traffic so as to know which pages are popular and which not.

From the analytics view point it gives valuable information about visitors data in relation to website pages. Lets have a look on few of them:

• Total number of visitors for specific page on site.
• Geographical location and network details.
• Average for number of page views and time spent by visitors.
• Most popular pages across different categories.
• Entry and exit statistics for understanding the visitor navigation behavior.
• Referring sources from where traffic is being generated.
• Server responses for error handling.

Note that not all the web traffic tool will provide all above mentioned details but these are the most valuable features that are expected. Lets have a look on these different web traffic monitoring tools one by one.
