7 Tips for Checkout Optimisation to Boost Your Conversions!

E-commerce checkout optimization is the process of reducing friction between a shopper's decision to buy and the completed transaction. A poorly designed checkout drives up cart abandonment, which averaged 70.22% worldwide in 2026 (Baymard Institute). Here are 7 tips to help you improve your checkout and boost conversions.

‍

1. Why does a mobile-first checkout matter?

‍

By 2025, mobile devices accounted for roughly 59% of global e-commerce sales (Statista), and that share reached an estimated 60% in 2026. Mobile traffic now represents about 75% of all e-commerce visits, yet mobile conversion rates still lag behind desktop (2.9% vs. 4.8%).

‍

Ensure your checkout process is designed with mobile users in mind, offering a responsive design and large, easy-to-click buttons.

‍

For instance, Amazon's one-click checkout is a prime example of a mobile-first approach that significantly reduces cart abandonment rates.

‍

‍

2. Offer guest checkout options

‍

Forcing users to create an account can be a significant barrier for first-time shoppers. If required to create a new user account, 23% of users will abandon their shopping cart. Baymard Institute's 2026 benchmark confirmed the same figure.

‍

By offering a guest checkout option, you increase the likelihood of visitors completing their purchase.

‍

For example, Nike allows shoppers to check out as guests, speeding up the process and increasing conversion rates.

‍

‍

3. How short should the checkout process be?

‍

The checkout process should not exceed 30 seconds, according to research by Forter. That 30-second window even includes the mandatory time for credit card security verification. The average checkout flow has 5.1 steps from cart to order review (Baymard Institute, 2026).

‍

Cut unnecessary form fields, use autofill functionality, and provide clear instructions.

‍

ASOS does this well by offering a clean, single-page checkout experience that minimizes distractions and accelerates the process.

‍

‍

4. Showcase trust and security

‍

In 2026, online security remains a top concern for shoppers.

‍

Display trust symbols like SSL certificates, secure payment badges, and customer reviews to reassure customers their data is protected.

‍

For example, Shopify-powered stores include a secure payment icon, and the platform is Level 1 PCI DSS compliant, ensuring maximum security for their users.

‍

‍

5. What payment options should you offer?

‍

Digital wallets are now the dominant online payment method globally. In 2025, digital wallets reached 4.4 billion users worldwide (Juniper Research), and that number is projected to exceed 5.2 billion by 2026. Apple Pay, Google Pay, PayPal, and regional options like iDEAL and Bancontact keep growing their share of checkout transactions.

‍

To cater to a diverse audience, provide multiple payment options: credit cards, digital wallets, Buy Now Pay Later (BNPL), and local payment methods popular in your target markets.

‍

Take Zara, for instance, which accepts Visa, MasterCard, PayPal, Klarna, and more, catering to a wide range of customers across Europe.

‍

‍

6. Optimize for speed

‍

A slow checkout process can lead to cart abandonment. Research shows that a 2-second delay in load time can increase bounce rates by up to 103%.

‍

Optimize your website's load time by compressing images, using a content delivery network (CDN), and minifying CSS and JavaScript files.

‍

‍

7. Use exit-intent pop-ups to reduce cart abandonment

‍

Exit-intent pop-ups detect when a user is about to leave the checkout page and display a targeted message, such as a discount or free shipping offer. This tactic can help recover up to 20% of abandoned carts.

‍

Look at fashion retailer H&M, which offers a 10% discount code to visitors about to abandon their carts, enticing them to complete their purchase.

‍

By implementing these 7 tips, you can improve your customers' shopping experience, decrease cart abandonment, and increase your conversion rates. Keep analysing and refining your checkout flow as payment methods, devices, and shopper expectations continue to shift.
