Most forms these days are bloated with too much distractions.
On any page that a user is supposed to focus, delete all navigational elements that distract them from the goal.
This means ...
- Remove the primary navigation
- Hide the footer
- Make the primary container of the form narrower (500px vs. 1100px).
You'll find more users will go through the forms, quicker, leader to a higher conversion rate across the board.
