All surveys end with a final page that appears when the respondent clicks the Send button. If you are creating tests or quizzes, you can add information about the result and additional comments on the end page. You can show respondents different end pages based on their responses.
Depending on your logic, you can use multiple end pages and redirects in the same form, but respondents will only see one end page or redirect.
On the final page, you can add a button redirecting the respondent to the indicated website. For instructions on how to add a redirect, see this article: Redirect after survey completion
