Traffic Analyzer = Traffic + Analyzer

Traffic: Traffic is volume of visitors to a website. Traffic is the currency of online success, but is not the only factor. Massive, low grade traffic to a website with poor content will inevitably result in failure
Analyzer: Analyzer is an instrument or device or a tool, which can determine qualitatively and quantitatively the components of the traffic.

This is basically a tool to analyze the traffic or the nature of the traffic. We use AWSTATS for this purpose but if the website is hosted on some other server, than AWSTATS needs to be installed and configured.
Report: Following things are analyzed and mentioned in the detailed report
- Summary
- Number of visits in a day
- Weekly report
And there are n number of ways and m number of parameters with which you may analyze a particular URL.
