After you log in, what kind of options do you have for questionnaire creation? Are you able to upload survey questions that you already have and use them in your questionnaire? Do they have a template library filled with pre-made surveys? If they do, how big is it and how many different areas of research do they cover? If you just need to start from a blank template, what sort of options do you have? Can you pick from over 30 different question types, including basic multiple choice and advanced types that employ multimedia? Can you also include branch logic in your surveys?
When you go with QuestionPro, you can have all of these features, plus more.
