Form design is a critical element. A good form lifts conversion; a bad one drives users away. Up to 80% impact on conversion.
Number of fields
Fewer is better. An 11-field form converts 120% worse than a 4-field one. Only what you need.
Label position
Above the input is best. Inline saves space but disappears. Float label is modern.
Input design
Border, 12-16px padding, 5-8px border-radius, clear focus state.
Placeholder
An extra hint, not a label replacement.
Required/optional
Use * for required or \"(optional)\".

email, name, tel, address. The browser fills in automatically.
