Tips to Optimize Checkout for More Sales
Having a great tool is a solid start. Pair it with these strategies for even better results:

And remember: People don’t want to think too hard when buying. A smooth and simple experience leads to more happy customers — and more money in your pocket!
One More Thing: Test Everything
Every store is different. So, test your checkout page to see what works best. Try new layouts, colors, and payment options. Small changes can lead to big results.
