Checkout Optimization: How to Reduce Cart Abandonment by 40%

Cart abandonment is one of the biggest challenges in e-commerce. On average, 70% of visitors leave their shopping cart without checking out. That means billions in missed revenue, but also a huge opportunity to recover.

In this guide, we share the proven optimizations we implement for our e-commerce clients at Saerens Advertising.

The Numbers That Matter (2025)

Metric	Value
Average abandonment rate	70.19%
Mobile abandonment	85.2%
Desktop abandonment	72.6%
Annual missed revenue (US)	$18 billion
Recovery email open rate	39-42%
Recovery email conversion	10.7-11%

Why People Drop Off: The Top Reasons

1. Unexpected costs (48%): shipping costs, VAT, and handling fees that only become visible at checkout
2. Account required (25-26%): nobody wants to create another account
3. Complex checkout process (18%): too many steps and form fields
4. Limited payment options (13%): preferred payment method not available
5. Security concerns (18%): no trust in the webshop
6. Just browsing (43%): not ready to buy

Proven Solutions

1. Show All Costs Early

48% of abandonment comes from unexpected costs. The solution:

• Show shipping costs on the product page or in the cart
• Use a shipping cost calculator based on postal code
• Communicate free shipping thresholds clearly

This alone can reduce abandonment by 15%.

2. Offer Guest Checkout

25% drop off due to required account creation. Always offer a guest checkout option. Account creation can happen after the order.

3. Streamline the Checkout Process

• Reduce form fields. The ideal is 12-14 fields (the average webshop has 23!)
• One-page checkout can increase conversion by 21% vs. multi-step
• Show a progress indicator
• Enable auto-fill for faster input

4. Mobile Optimization

With 85%+ mobile abandonment, this is essential:

• Mobile-first design
• Fast load times (53% leave if it takes longer than 3 seconds)
• Mobile wallets (Apple Pay, Google Pay)
• Thumb-friendly buttons
• Minimize typing on small screens

5. Build Trust

18% drop off due to lack of trust. Add:

• Trust badges and security certificates
• Quality marks (Trusted Shops, etc.)
• Customer reviews and ratings (reduces abandonment by 11-15%)
• Clear return policy (can reduce abandonment by 28%)
• Payment method logos

6. Multiple Payment Options

• Credit card, PayPal, Klarna
• Buy Now Pay Later (BNPL), a growing preference especially among younger shoppers
• Apple Pay, Google Pay for fast checkout

Recovery Strategies

Abandoned Cart Emails

With 39-42% open rate and 10-11% conversion, these are your best recovery tool:

• Send the first email within 1 hour for best results
• Use a 3-email sequence
• Include product images, names, and prices for personalization
• Strategically offer discounts or free shipping as incentives
• Add low stock alerts or time-limited offers for urgency

Exit-Intent Popups

Average conversion: 17.12%

• Offer discount or free shipping at the moment of leaving
• Mobile-optimized, easy to close
• Gamification (spin-to-win wheels) increases engagement
