Professional survey

A professional survey is a systematic questionnaire that the target audience fills out online, usually by filling out google forms. Professional surveys can vary in length and format. The data is stored on a website and the testing tool usually provides a certain level of data analysis in addition to a professional expert review. Several professional online survey softwares are present worldwide like, SoGoSurvey, SurveyGizmo, SurveyMonkey, Qualtrics, and so on.
