What is a key advantage of using progressive polling forms in Marketo?

Progressive polling forms in Marketo are designed to enhance the user experience by dynamically updating the fields presented to users based on their previous submissions. The primary advantage of using these forms is their ability to gather incomplete information over multiple interactions. When a user submits a form, Marketo remembers the information already provided. On subsequent visits, the form will only display new fields that the user has yet to complete, thus reducing redundancy and improving completion rates.

This approach not only streamlines data collection but also helps maintain user engagement by not overwhelming them with questions they have already answered. By fostering a more personalized experience, marketers can effectively enrich their prospect profiles with relevant data without frustrating the user. This dynamic updating capability differentiates progressive polling forms from traditional static forms, which ask for the same information every time and potentially decrease the likelihood of form completion.
