Questionnaires and web trials allow research workers to reach a far wider target market than traditional paper forms, telephone or face-to-face interviews and can be conducted in a cheaper cost. This will make them a popular tool to get market research and customer research as well as factors research. However , irrespective of their many advantages they come with some negatives which can challenge the validity of the results.

To counter this, you can use an online marketplace including SONA devices (often used for undergraduate evaluating at universities), MTurk or Legendary to recruit participants.
