How do I optimize the checkout process for higher conversions in ecommerce?

To optimize the checkout process, streamline the steps, minimize form fields, and offer a guest checkout option to reduce friction. Display a clear progress bar to show users how many steps are left. Provide multiple payment methods, including popular options. Highlight trust signals like secure payment icons and customer reviews. Ensure the process is mobile-friendly and consider exit-intent popups to reduce the abandoned cart rate and boost conversions.
