If you want users to complete your form, remember one simple rule: the less, the better. So, reduce the number of fields to the minimum. How to do so? Ask yourself a basic question: 'Which fields are critical for me and which I can cut out?' To simplify your form, consider hiding such fields as 'Address 2', 'Discounts', and 'Company Name' (they're used quite rarely) behind a text link until they’re needed.
