What happens if only a small percentage of users answer the questionnaire?
This depends on what you mean by “small”. In a postal survey, for instance, 10% response rate is considered normal. If you are basing your statistics on server usage statistics then be sure you know what these statistics are showing and how they are calculated. If you do find a very small WAMMI response rate as compared to your site usage, we would recommend that you set up a “user panel” consisting of 20 to 40 regular, committed users, and get an undertaking from them to visit your site in a certain period and fill out the WAMMI questionnaire for you. You may also find this user panel useful for other activities when you are improving your site. The user panel may be small compared to your estimated hit rate, but you will have the satisfaction of knowing that this is quality data.
