Which factor has a higher impact on conversion rates: aesthetic design or technical performance?

All answers to this question.

When it comes to the checkout phase, performance is the ultimate psychological trigger for trust. A slow or "laggy" payment page makes users nervous about whether their transaction went through or if their data is secure. We helped an e-commerce client last year who was obsessed with a "premium" checkout look that used heavy scripts. By stripping those scripts and making the transitions instantaneous, their cart abandonment rate dropped by 22%. While the design needs to look professional and clean, the "feel" of a fast system does more to build trust than a fancy gradient or custom font ever could.

Sharon, that's interesting, but wouldn't a site that looks like it was made in 1995 also scare people away even if it was lightning fast?

• Kyle, you're right, there's a baseline of "modernity" you have to meet. Nobody is suggesting a text-only site. The sweet spot is "Invisible Design"—where the UI is so clean and the performance is so fast that the user doesn't even notice the technology. They just focus on their task. If the user is thinking about how the site looks or how long it’s taking, you’ve already lost their primary attention.

I've always found that "performance" is actually a feature of good design. If it doesn't work well, it isn't designed well. They aren't really separate things.

• I agree with Heather. High performance is a sign of a high-quality product. It shows the company cares about the user's time and resources.
