The Value of Web Statistics

The answers to these questions can be found using web statistics.

What are web statistics?

Intranets are usually run on a webserver. This webserver not only provides pages to users, but tracks exactly which pages are accessed and when.

This information can be analysed by a web statistics package (also known as a "log analyser") to provide considerable information about the usage of the intranet. While exactly what statistics can be gained will vary, depending on the package used, a good package will provide you with:

• daily and monthly summaries
• graphical charts of usage
• number of hits and pages
• most popular pages
• largest amount of downloads
• overall network traffic
• browsers used to access the intranet

It may be possible to gain considerably more information than this, so shop around, and see what web analyser software is available for your platform.

Who can make use of web stats?

Everyone.

All major webservers (such as Apache, IIS, iPlanet, Netscape) have either built-in web statistics packages, or are well- supported by a wide variety of both commercial and freeware packages.

If you are the administrator of your webserver, you can install software directly on the server. Alternatively, as long as your administrator can provide you with the server logs, you can run statistics software on any workstation.

An example: webalizer

The following examples were generated using Webalizer, a completely free web statistics program that works well on Apache and Linux. While there are many other packages on the market, they will give similar results to those shown here.

Beside each sample is the list of questions (see the beginning of the article) that can be answered using the provided information. Note that some questions are best answered by using a number of the provided statistics.

Graph of monthly usage

Shows at a glance the overall state of intranet usage, as well as the growth or decline in usage.

Questions answered:

• How heavily used is the intranet?

• Is the usage growing or falling?
  This graph will clearly show whether usage is increasing or falling. If usage is going down, or not growing at a reasonable rate, it's time to starting thinking about further marketing your intranet.

  If growth is poor, you might also want to check whether your users are struggling to understand the design of the intranet. This can be done using some simple usability testing.

Table of monthly usage

This shows the same information as the previous graph, but in a numerical format that lends itself well to in-depth analysis.

Questions answered:

• How much load is the intranet placing on the network?
  The total number of kilobytes downloaded will show the load on the network generated by your intranet. Most packages will also show a breakdown by hour, or even minute.

  This information may be of value to your network administrators: if nothing else, it may reassure them that the intranet is not adversely impacting the overall speed of the network.

• How heavily used is the intranet?
