People who start and stop.
WHY THEY STOP
Too many fields A field they do not want to give An error they cannot resolve Uncertainty about what happens next It is difficult on a phone
THE ERROR PROBLEM
Unclear errors stop people entirely.
Errors should name the field and say what is wrong, beside that field.
THE PHONE NUMBER FIELD
Some hesitate to give it.
Stating why you need it helps: "So we can call you back with a quote."
VALIDATION
Should be forgiving.
A phone number rejected because of a space or a country code loses the enquiry.
REQUIRED FIELDS
Mark them clearly.
Only make required what you genuinely need.
THE SUBMIT BUTTON
Say what it does. "Send enquiry", not "Submit".
MOBILE KEYBOARDS
Set field types so the right keyboard appears.
WHAT TO TEST
Deliberately trigger every error and see what the visitor experiences.
