Deffination:

A web analytics is  a series of reports of quantitative indicator of the behavior of the visitors of the website. It tracks the movement of visitor and the reason of his/her visit. In other words, it provides the clear report of the performance of your website and the trends. From these reports and trends the website owner creates and implements more effective program to increase sales.

Web Analytics are based:

• Collection of visitor’s data from logfiles, and
• by tagging each webpage with a Javascript.

A third web analytics method is a combination of the two whereby more relevant data can be produced than what is possible with either of the two methods.

Web Analytics Terms:

Number of visits means that how many visitors landed on any page of your website from any source. In the case of log files of server, it will log several files for each visit, while the page-tagging script will only consider the page as a whole seen by the visitor. In either case, each web analytics data will clearly identify if the visitor is new or has come before.

Page Views means different for the two web analytics methods. While tagging script considers the whole page as one request, the logfile on the other hand will record multiple hits (one for each file, including images, .js and .css) within a single page-view.

Hits denotes requests for files from server and is recorded only in logfile.

Unique visitors means new visitors, it is noticed by logfiles as well.

The length of time a visitor spends in seeing a website.

The keyword phrase used to arrive at the website.

The unique IP address and therefore the country from where the visits generated

Visits duration

Files type etc

Data transfer to and from the server is always recorded in server’s logfile with clockwork precision. And these files can be easily viewed in web analytics programs such as Webalizer, Awstats, etc. which analyze raw logfile data and portray valuable visitor information in easy-to-follow graphics.

What is difference between Logfile and Page Tagging:

• Logfile analysis is usually already available in the server. Page tagging is an outsourced option, which means that visitors’ data is captured by provider’s remote server.
• Logfile analysis can be viewed only in provider’s website, while Google Analytics and ClickTracks are examples of page-tagging web analytics.
• Since page tagging requires javascript to be installed on every webpage, there is always a possibility that some visitors’ browsers do not allow the script to run. Whilw logfiles have no such issue.
• Logfiles enter transfer of all files, including images and scripts, and therefore certain parameters like hits and page views are not as accurate as with page-tagging web analytics.
• While logfiles record visits by search engines, page tagging does not.
• Logfile web analytics record failed visits too. Page tagging takes a request into account only when a webpage is successfully displayed.

Web analytics is a type of feedback from visitor which is available all times. These reports are a great source by which you can analyze relative strength and weakness of your website. From these, you can find which pages are most visited and which keywords are more related to your web site.
