Web site statistics l.jpg

Web Site Statistics

  • This presentation will:

    • Give a (very) brief overview of what Web statistics are

    • Consider why we need them

    • Focus on the analysis of usage data created by your Web site

    • Look at what other criteria, besides Web server statistics, can be used to provide performance indication

Sustainability Workshop, London, 16 May 2002


What are web statistics l.jpg

What are Web Statistics?

  • Web statistics are produced by the Web server software

  • Information (such as IP address, name of resource) is recorded in a log files

  • It is also possible to configure your server to record more information (such as referrer details)

  • The log files produced are mainly accurate

  • However interpretation of the statistics can be misleading

Sustainability Workshop, London, 16 May 2002


Why do we need them l.jpg

Why do we Need Them?

  • They indicate how popular your site is

  • They show how successful your marketing strategy has been

  • They can be used in management reports

  • They can identify gaps in service provision

  • They predict and plan for future load patterns

  • They allow you to monitor performance levels

  • They can be used in consideration of deployment of new technologies

  • They can inform and motivate contributors

  • They can show who your users are

  • NOF have asked for them

The http process l.jpg

The HTTP Process

  • A user clicks a link or enters a URL

  • The remote web server downloads the HTML page

  • The HTML page is interpreted and any inline objects are also downloaded:

    • Each image (occurrence of <IMG SCR=“image1">)

    • Background image or sound

    • External JavaScript or stylesheet files etc.

  • The user follows a path through the site making new requests till they leave your site

Summary

Each individual users request for a page can produce multiple requests at the remote server and generate multiple hits.

Viewing web statistics l.jpg

Viewing Web Statistics

  • Server log files are available to view…but may not make a lot of sense on first look

  • The Analog program (Cambridge University) was one of the first packages to provide a graphical summary of web log file.

Web statistics terms used l.jpg

Web Statistics: Terms Used

  • Hit

    • Any information requested from a site - this includes HTML pages, pictures, forms, scripts and files downloaded

    • Can be affected by redesign, robots, caching etc.

  • Page Views (or requests/impressions)

    • The number of pages viewed

    • Extensions such as .htm, .html, .asp etc.

  • User Sessions

    • Series of requests from unique IP address within a period of time (more accurate if registered users

    • Issues with firewalls, institutional caches etc.

Sustainability Workshop, London, 16 May 2002


Interpretation issues l.jpg

Interpretation Issues

  • Profiling users - can we track users easily?

    • You can’t tell the exact identity of your users

    • Using IP addresses, domain names of visitors

    • Following paths – entering and exiting the site

    • Registration

  • Caching

    • Browser caching and institutional/ISP caching

  • Robots

    • Necessary enable your resources to be found

    • Robots generate hits

  • Quality??

Log analysis tools l.jpg

Log Analysis Tools

  • There are many tools available:

    • Analog: free, easily automated. However little data-mining capabilities and management graphs limited.

    • WebTrends: Popular desktop package. Several versions. May be expensive for reporting on multiple Web sites.

    • Webaliser, WebVisit, HitList, Reportmagic etc.

    • A list is available at http://uk.dir.yahoo.com/Computers_and_Internet/Software/Internet/World_Wide_Web/Servers/Log_Analysis_Tools/

Externally hosted services l.jpg

Externally-Hosted Services

http://www.sitemeter.com/

  • Two services have been used extensively by UKOLN: SiteMeter and NedStat

    • Advantages:

      • No software to buy, install, configure and run or powerful PC to run software on

      • No log files to manage

      • Uses "cache-busting" images

      • Can monitor extra features

    • Disadvantages:

  • Limited data-mining

  • Lloss of Ownership of data

  • Dependency on external service

  • Fails to monitor text browsers

Conclusions
