Only ask for the information they need. The more fields you ask visitors to fill out in your form, the less chance you have of them completing your offer. If your conversion requires a form, get the bare minimum of what you need – you can always ask for more info on the thank you page once the deed is done. While most users don’t have a problem providing their name and email address, asking for info about phone numbers and date of birth can cause your drop off rate to skyrocket to 50%. The rule of thumb is not to include more than seven fields in your lead gen form on your landing page.
