If you want to anger customers, I have the strategy for you:

Make your web form, signup for, or job application abnormally and unnecessarily long.

A report from Marketo said that when a form went from nine fields to five, form conversion rates improved by 34%!

It is amazing how many web forms are unnecessarily long.

Make it easy for people to get started. Especially if those people are not ready to purchase.

How will you know how they are ready? They will tell you.
