Website testing

Some tools to :

  • Analyse the behaviour of internet users when using different scenarios of a website, and examine the difficulties they have…
  • Analyse how user friendly a website is in terms of navigation, content, functionality and its clarity…
  • Analyse the global perception of a website in terms of service, and in particular identify the needs which are not satisfied (or hardly satisfied), unnecessary or lacking functions

Based on the observation of the behaviour of the internet users targeted this qualitative survey can be carried out either face to face or by interviewing the people on the screen.

These observations enable an analysis of the ergonomics of the website and how functional it is according to the 7 criteria of usability :

  • Compatibility : the website’s capacity to integrate with the activity of users…
  • Steering : the capacity of the website to guide and orient the user, to enable the user to find his/her way around
  • Homogeneity : the capacity of the website to preserve a basic logic for use which is consistent
  • Adaptability : the capacity of the website to adapt to the different strategies of the users according to their objectives and their habits… 
  • Action control and management of errors : the capacity of the website to interact with the user, and to limit incorrect orientations, by emitting messages.
  • Concision : the capacity of the website to present brief and clear information to optimize the time spent and improve access.
  • Relevance : the capacity of the website to prioritize the headings and themes, whilst taking into consideration the different levels of reading according to where the user is situated.

The key stages

Survey fieldwok

  • The participants are asked to consult the website and/or to buy something
    - The consumers interviewed will be given an objective for their task
    - Left to surf freely, they must achieve this objective.
    - Their experience is observed closely while it is actually taking place.
    - Afterwards, an in depth interview is conducted

The analysis, in several stages

  • Detailed evaluation of remarks about each surfing
  • Analysis of the different types of experience, the difficulties encountered
  • Drawing up of a comparative chart containing objective and measurable criteria (time spent on each phase/or action, number of screens displayed, number of pages not visited…)
  • Synthesis of the results according to the criterion of usability

The composition of the sample

  • Each test is made, individually, with 5 to 8 people from the same target.
    According to J. Nielsen and T. Landauer, 85% of the problems of usability of a web site can be detected by a sample of 5 users. These figures have been confirmed by the tests that we made : It is preferable to carry out several tests during the development of a website or to focus on functional or target sub-sets rather than to use a bigger sample for a single test.
