IMAO, neither is perfect. Going for all-in-one-page has already been described in the previous answer.

On the other hand, one question per page is quite boring and monotonous. Survey designer should keep in mind that participating a survey is a favor from the user, not the other way. Keeping the questions interesting, concise while effective is the way to go. And mind the click count. Loading different pages on slower networks as well as on mobile will quickly render the user frustrated.

In your scenerio, i would group the 10 must-ask question into just 2/3 pages while keeping the order of the questions random, unless sequence between questions is necessity.

I would keep "make-it-interesting" as top-priority.

Survey designer should

• keep in mind that participating a survey is a favor from the user, not the other way around.
• Keep the questions interesting, concise while effective.
• And, mind the click-count. Loading individual pages on slower networks, as well as on mobile, will quickly frustrate the user and push him subconsciously to give up.

In your context, i would

• group the 10 must-ask questions into just 2/3 pages
• keep the order of the questions random, unless sequence between questions is necessity.
• keep "make-it-interesting" as top-priority. Effectiveness will follow.
