If you guys aren’t already familiar with Persuasive Design, I suggest doing some reading on the subject. You’ll find it fascinating!
I first began studying persuasive design back in 2007 when I had to write copy for the Sears/Kmart websites. Let me tell you, it was no easy task. How do you get tens of thousands of people to purchase items with the least amount of words as possible?
Users don’t want to think about what they’re reading. Keep it short and simple. You will find your conversion rate per task to be higher by doing so.
If you want your users to do something learn how to get them to say “YES.”
Here are 6 powerful compliance triggers to get users to say “yes” from http://www.copyblogger.com/get-to-yes/.
1. Reciprocation
2. Commitment & Consistency
3. Social Proof
4. Liking
5. Authority
6. Scarcity
BTW, my favorite one is Scarcity. In the world of e-commerce I believe it is the biggest component of selling large quantities in a cyclical, short period of time. We performed A/B testing using different words and phrases such as Limited Quantity, Sale Ends Soon, Limited, x Days Left, etc. so that users felt compelled to purchase an item before it was too late. I will admit that sometimes I felt bad about doing so, but it’s the nature of the beast. If you want to sell, use the tools of persuasion. Check out a previous post of mine Amazon.com Lightning Deals … time is running out! and see it in action.
Researching on the Web will give you even more valuable data and test cases that you can use in your arsenal when trying to explain the ROI on some of your UX decisions.
