We are thinking of conducting a Max-Diff study to test 6 commercial ad videos (30 seconds each). The videos are not entirely different from one another, but only different at a couple of places during the entire video (in terms of the tagline, product shown).
We wanted to reach out for help to see if Max-Diff is the best way to do this or are there any simpler / better / more creative alternates we could go with? (like doing a pairwise testing for A vs B, C vs D, E vs F on three screens and then another one to compare and rank all the individual winners). Also, what would be the key consideration points when conducting such a Max-Diff test?
Our sample size is 800, we are looking at gen pop and the total length of the study will be ~10-12 mins.
Please let us know your thoughts or if you have any other questions. Thank you in advance for your help,
