OPTIMIZING FORM FIELDS
1. Cost doesn’t just exist where monetary transaction exists. Any time you ask a prospect to give up something (material or mental), there will be an implicit/explicit cost.

1. Cost doesn’t just exist where monetary transaction exists. Any time you ask a prospect to give up something (material or mental), there will be an implicit/explicit cost.
2. There are two factors that impact the cost as it relates to requesting a prospect to give up information.
• The amount of information required
• The nature of the information required

OPTIMIZING FORM FIELDS
Have you eliminated (or made optional) as many unnecessary fields as possible? Are the forms organized to reduce friction? Are they sequenced to the visitor’s thought-sequence. Is your value proposition being expressed throughout the entire conversion process? Have you provided clear justification for all the high-anxiety producing form fields? Do you have security seals? Privacy policy? Does your error messaging clearly lead your visitor to completing the form?
Form Field Checklist

KEY QUESTION
But what about business objectives? What about lead quality?

WHAT ABOUT QUALITY?
Didn’t making a form field optional hurt the
lead quality?

3. Marketers can leverage costs (both amount and nature) in order to determine the optimal number of required form fields.
