When editing the questionnaire, you can specify a static display of the introduction in the introduction settings.
If a respondent clicks on the Introduction page and then leaves the survey without clicking anything else, the respondent is given a status of '3' and is recorded in the database as a non-valid unit. If this is not desired, we can enable static display of the introduction, which means that a respondent who clicks on the survey and is shown the introduction will not be recorded as a respondent until they click on the next page. In this case, the respondent will only be recorded in the database when they click on the next page.
Static display of the introduction is particularly recommended if the survey is published as an embed on a web page or to avoid false (computer-generated) clicks on the survey.
Additionally, to avoid fake clicks on the survey, the introduction can be set to display and verify with a CAPTCHA test, where the respondent must first prove that they are not a robot (program).
