We are interested in running a purely quantitative remote web-based user test with 100 specific users. Where we show them different design variations of a concept and ask them to vote for the one they like best. Then we will tell them the purpose of the design and ask them to vote again. This test would be sent out to targeted users, conducted remotely and self-service via a questionnaire/presentation type format.
The goal is to get another level of feedback about some new design variations we are trying in addition to the more qualitative user testing sessions we are doing.
Are there any key things or best practices we should be aware of and/or focused on when trying such an approach?
