reduce form fields
Editor’s Note
Dear Marketer,
We know you’ve been struggling to convince your boss and Sales leaders to
reduce the number of form fields on your landing pages.
Some leaders need a little more proof than others.
To help you win them over in the fight to reduce frustrating form fields
(and improve your conversion rates), we’ve created this deck with three
case studies showing how reducing form fields gets results.
Please feel free to download it and customize it for your own boss. You’ll
look and feel a whole lot smarter when you pitch them with an impressive
deck and numbers to back you up.
Sincerely,
The MarketingExperiments Editorial Team
