How Warby Parker Crushed Buyer Fear with a Guarantee
See how eyeglasses brand Warby Parker used risk reversal and guarantees in their Facebook ads to dominate the online eyewear market.

Introduction
Buying prescription glasses is a big deal. You wear them on your face every single day! When Warby Parker started selling glasses on the internet, people thought they were crazy. How can you buy glasses without trying them on first?
The Challenge
Warby Parker had a massive friction point. People liked the styles and the prices, but they were absolutely terrified that the glasses would look bad on their specific face shape.
The Ad Strategy
They used the "Risk Reversal" and "Trust Badge" ad hooks. Their ads featured a beautiful pair of glasses, but the main text wasn't about the glasses at all. The big, bold text said: "Try 5 Pairs at Home for Free." They made it perfectly clear that if you didn't like them, you could send them back and pay zero dollars.
The Results
By offering a crazy guarantee right on the image ad, they completely destroyed the customer's fear. Millions of people ordered the free trial boxes, and a huge percentage of them ended up buying a pair. Warby Parker disrupted the entire eyewear industry.
The Key Takeaway for Your Store
If people are nervous to buy your product online, offer a powerful guarantee and put it in big, bold letters right on your ad image. Make them feel totally safe.
