Online feedback forms come in many different shapes and sizes. To initiate these different types of feedback forms on a website or mobile app, two different methods are used: a passive approach (e.g. a feedback button on the side of your website) and an active approach (e.g. triggering a feedback form when a customer reaches a certain goal on the website, or when a visitor leaves the page).
