It’s the most important button

• Choose a color that is both contrasting and fits your brand
• Make sure the Add to Cart button attracts the most attention on the page, compared to other buttons or links

Be descriptive

Test descriptive labels for the button. For example, if you promise to deliver the next day, you could test a button that says Buy Now to Get It Tomorrow.

Other ideas from GrowCode:

• Buy Now to Get 50% Off
• Buy Before 5 PM for Free Delivery
