Most online stores do not lose sales in one dramatic moment. They lose them in small ones: a surprise shipping charge, a search that returns nothing, a form that rejects a postcode, a vague returns page, a delivery date that slips without warning. Each feels minor. Together they decide whether a visitor becomes a customer, and whether that customer comes back.
Ecommerce customer experience (CX) is the discipline of finding and fixing those moments. It is not a logo refresh or a loyalty scheme. It is the practical work of making every step from search result to second order feel easy and safe.
This guide maps the moments that cost the most sales, shows what research says about why shoppers leave, and gives you a step-by-step audit you can run this month.
Key Takeaways
- Customer experience covers discovery, product evaluation, checkout, delivery, returns and support.
- Unexpected costs, slow delivery, trust concerns and forced account creation are leading reasons shoppers abandon checkout.
- Baymard’s benchmark found 65% of large US and EU ecommerce sites had mediocre or worse checkout UX.
- Clear policies, accurate delivery promises and easy returns protect both conversions and repeat purchases.
- Measure CX with behaviour data and direct customer feedback, then fix the biggest drop-off first.
Why Customer Experience Decides Ecommerce Revenue
Baymard Institute’s running list of 50 cart abandonment studies puts the average documented online cart abandonment rate at 70.22% (page updated September 2025). Some abandonment is unavoidable, since many people add items to save or compare. But Baymard’s own survey of US shoppers shows a large share of exits are caused by the store experience itself.
| Reason for abandoning checkout (US shoppers) | Share | CX fix |
|---|---|---|
| Extra costs too high (shipping, tax, fees) | 40% | Show full costs early; review your free shipping strategy |
| Delivery was too slow | 20% | Offer faster options and show delivery dates on product pages |
| Did not trust the site with card details | 19% | Visible security cues, recognised payment methods, reviews |
| Site wanted me to create an account | 18% | Offer guest checkout |
| Checkout too long or complicated | 17% | Remove fields and steps |
| Website had errors or crashed | 17% | Test checkout across devices and browsers |
| Return policy not satisfactory | 13% | Clear, fair, easy-to-find return terms |
| Could not see total order cost up front | 12% | Cost calculator or estimate in cart |
Source: Baymard Institute, excluding the 42% who said they were "just browsing". Shoppers could choose multiple reasons.
Baymard’s checkout benchmark of 344 top-grossing US and EU sites also found that 65% had mediocre or worse checkout UX, and estimates that the average large-scale site could see a 35% increase in conversion rate through better checkout design. That is a potential, not a promise, but it shows how much revenue sits in usability.
The Moments That Lose Sales
1. Discovery and first impression
Shoppers arrive on product and category pages from search, ads and social, not just your homepage. If the landing page is slow, cluttered or does not match the promise of the ad or search snippet, they leave. Fast pages and clear headings are basic CX.
2. Search and navigation
A search that returns zero results for a common spelling mistake is a closed door. Filters that do not match how people shop are a maze. Our guide to ecommerce site search covers how to fix both.
3. Product evaluation
Shoppers need size, compatibility, materials, delivery date and total price to decide. Missing information creates doubt. Strong photos, honest reviews and clear copy all help; see our guides to product photography and writing product descriptions.
4. Checkout
The research above points to the same few fixes: no surprise costs, guest checkout, fewer fields, familiar payment methods and helpful error messages. Our dedicated guide to checkout optimization walks through each.
5. Delivery and communication
After payment, anxiety rises. Order confirmation, dispatch and tracking messages reduce "where is my order?" contacts. In the US, the FTC’s Mail, Internet, or Telephone Order Merchandise Rule also requires sellers to have a reasonable basis for the shipping times they state, and to get consent or offer a refund if they cannot ship on time.
6. Returns and support
A returns process is part of the sale. Clear policies increase confidence before purchase, and smooth returns protect loyalty afterwards. Google also lets you surface returns information in search results:
“display return policies alongside your products and in knowledge panels in Search results”

How to Audit Your Ecommerce Customer Experience: Step by Step
- Map the journey. List every step from search result to repeat order. Nielsen Norman Group describes a journey map as "a visualization of the process that a person goes through in order to accomplish a goal". Our customer journey mapping guide shows how to build one.
- Pull the funnel data. In analytics, measure drop-off between product view, add to cart, checkout start and purchase, split by device. Our guide to GA4 ecommerce tracking covers the setup.
- Shop your own store. Buy a product on mobile as a new customer, then return it. Note every hesitation.
- Read the support inbox. Tag tickets by theme. Repeated questions show where pages are unclear.
- Ask customers. Run a short post-purchase survey and an exit survey on checkout.
- Prioritise by impact. Fix the step with the largest drop-off and the clearest cause first.
- Test and measure. A/B test major changes where traffic allows, and track conversion, returns and repeat purchase rate.
Measuring CX
| Metric | What it shows | How to collect |
|---|---|---|
| Conversion rate by device | Overall ease of buying | Analytics |
| Checkout step drop-off | Where friction sits | Analytics funnel report |
| Customer Effort Score | How easy a task felt | Post-purchase or post-support survey |
| CSAT | Satisfaction with a specific interaction | Survey after delivery or support |
| Net Promoter Score | Likelihood to recommend | Periodic customer survey |
| Repeat purchase rate | Whether the experience earns loyalty | Store or CRM data |
Common Mistakes
- Revealing costs at the last step. The top abandonment reason in Baymard’s data is extra costs.
- Forcing account creation. Let people buy first and create an account afterwards.
- Over-promising delivery. Optimistic dates that slip damage trust and can create legal risk.
- Hiding the returns policy. Link it from product pages, the cart and the footer.
- Fixing based on opinions. Use funnel data and customer feedback to choose what to fix.
- Forgetting the post-purchase experience. Delivery updates and helpful follow-ups, such as those in our guide to post-purchase emails, turn first orders into repeat customers.

Frequently Asked Questions
What is ecommerce customer experience?
It is the sum of every interaction a shopper has with your store, from finding you in search, through browsing and checkout, to delivery, returns and support. Good CX makes each step easy, clear and trustworthy.
What is the biggest cause of lost online sales?
In Baymard Institute's survey of US shoppers, the most common reason for abandoning checkout (excluding people who were just browsing) was extra costs such as shipping, tax and fees being too high, cited by 40%.
How do I measure customer experience in ecommerce?
Combine behaviour data (conversion rate, checkout drop-off, return rate, repeat purchase rate) with feedback measures such as customer satisfaction (CSAT), Net Promoter Score and Customer Effort Score, plus support ticket themes.
Should I force customers to create an account?
Generally no. Baymard found that 18% of US shoppers had abandoned an order because the site wanted them to create an account. Offer guest checkout and invite account creation after the purchase.
Does customer experience affect SEO?
Indirectly. Fast, usable pages and clear policies help users and support signals such as Core Web Vitals, and Google can show return policies alongside products when you configure them in Merchant Center or with structured data.
Conclusion
Great ecommerce customer experience is rarely about one big idea. It is about removing the small frictions that make shoppers hesitate: surprise costs, missing information, long forms, vague delivery and difficult returns. Map the journey, measure the drop-offs and fix the biggest ones first.
