You can include more than one poll unit on a page by placing multiple copies of the integration code in the HTML code for your page. Make sure that you use different ID attributes for the <div> element in each placement of the integration code.
When more than one poll unit is included on a page, each instance is unaware of the others and, importantly, the questions being asked in the other instances during that page visit. Thus, it is possible for a respondent interacting with multiple instances of the poll unit on the page during a single page visit to be asked the same question more than once.
