Every survey is made up of Pages and Questions. You can choose from a range of questions and place them on a single page or spread them across several pages. All the questions on a single page will be displayed to the respondent at once. If questions are spread across multiple pages, only one page is displayed at a time with a button for the user to click to advance to later pages.
It's always a good idea to break up large surveys into multiple pages. As each page is completed, the respondent's information will be checked for errors and prompted to make any necessary changes. This way they won't get too far before filling out the correct information.
