It has been proven that fewer fields lead to more visitors, and therefore, more revenue per year. This is very important to consider not only when creating a business card website , but also when creating a landing page . After Expedia removed just one field from their signup form, their sales skyrocketed, and it turns out that this one extra field was costing them $12 million per year. According to marketingtechblog.com, your conversion rate can increase by 50% if you reduce the number of fields to 2-3. And yes, this means that you are losing about half of your sales due to an overly long signup form. Can you afford that? Probably not.
2. Use responsive placeholders
Floating labels are very often used in registration forms: they are simple, elegant and very user-friendly. Their advantage is that they combine the advantages of a simple placeholder and text that appears in the upper left corner of the field. When you click on the corresponding field, the placeholder text disappears and moves to the upper left corner of this field. This way, the user will never get confused about what information he should enter in a particular form field.
