Motivation: Current
Why do we need to analyze log files?
• More and more consumers use the internet as their primary source of decision making
• Companies not optimizing their internet presence will face a competitive disadvantage
• Usability testing cannot be afforded by many SME• Usability testing cannot be afforded by many SME
• Log files are a comparatively cheap and easy way to obtain large amounts of usability data
• Log files contain vital information about the web site visitor actions

Project goals
• Investigate the navigational behavior of website users by means of web analytics users by means of web analytics
• Discover navigational patterns that suggest usability problems (e.g. disorientation on a website)
• Develop a new pluginthis navigational behavior in order to detect such this navigational behavior in order to detect such usability problems
• Improve the competitive advantages of SME

• In our case: Structure of website
• Link between log files and structure of page
• Easy integration into existing architecture:

Realisation
Two components setup:
1. Hierarchy crawler: • Analyses structure of website• Platform independent (Java)
2. Piwik-plugin: • Links hierarchy data with log files• Deals also with existing log file data• Different analysis functions
