Ecommerce conversion optimization is the work of turning more of the traffic you already have into buyers. Most of it is small fixes, not rebuilds. And most of the money is not on your product page. It is in your checkout.

Start there. Baymard Institute's meta-analysis of 50 studies puts the average cart abandonment rate at 70.22%. Seven of every 10 people who add something to a cart leave without buying.
Some of that is unavoidable. Around 43% of shoppers say they were just browsing. Strip that group out and look at the reasons you can fix, and the ranking is clear:
Why people abandon Share Extra costs too high (shipping, tax, fees) 48% Site made them create an account 26% Checkout too long or complicated 22% Did not trust the site with card details 19% Total cost not shown up front 17%Source: Baymard Institute, updated September 2025. Shoppers could pick more than one reason.
Read that list again. Not one of those is a design problem. They are all things you decided, and can undo. Baymard puts the gain from better checkout design at about 35% more conversions for the average large store.
Here are 10 things to work on, roughly in the order they pay off.
1. Fix the cost surprise
This is the big one, and it is first for a reason. Nearly half of the people who abandon do it because the price went up at the last step.
Shoppers do not mind paying for shipping. They mind finding out about it after they have picked a product, entered an address, and started to feel committed. The cost itself is not the problem. The surprise is.
Show the full cost early. Put shipping on the product page or in the cart, not on the final screen. If you cannot afford free shipping, say the number out loud at the start and let people decide with the real figure in front of them.
2. Kill forced account creation
One in 4 abandoners leave because a store made them sign up.
Offer guest checkout. Then ask if they want an account after the order is placed, when they have a reason to say yes. You still get the email from the order. You lose nothing except the people who were never going to make an account in the first place.
3. Shorten the checkout
Around 1 in 5 abandon because checkout felt too long.
Baymard's testing suggests most checkouts can cut 20% to 60% of their form fields and still collect everything they need. Go through your own checkout on a phone and count the fields. Then ask what each one is for. Second address line, company name, title, phone number: each one needs to earn its place, and most cannot.
Show progress while they work. "Step 2 of 3" tells someone the end is near. It is a small thing that reduces the urge to give up.
4. Earn trust at the payment step
About 1 in 5 people abandon because they did not trust the site with their card.
That is a design problem you can solve with signals rather than words. Show the payment logos you accept. Show that the connection is secure. Show a returns policy that a person can read in under a minute. Put reviews near the buy button, not buried on a tab three scrolls down.
5. Offer the payment methods people use
Card and PayPal are table stakes. Apple Pay and Google Pay matter more than they used to, because they skip the form entirely on a phone. Buy-now-pay-later matters in some categories and not others.
Do not add every option you can find. Add the ones your customers ask for, then check whether anyone uses them.
6. Make the mobile experience the main one
Mobile abandonment runs far higher than desktop. Published figures vary by source, but the gap is consistent: roughly 80% on mobile against 66% to 73% on desktop.
Most stores still design on a laptop and check the phone at the end. Flip that. Build the phone version first, then let the desktop version be the easy one. Thumb-reachable buttons, no pinch to zoom, a keyboard that shows numbers when the field wants numbers.
7. Speed up the pages that matter
Page speed affects conversions, but not evenly. A slow blog post costs you little. A slow product page or cart costs you orders.
Compress your images and serve them in a modern format. Put a CDN in front of the site. Then stop. Chasing a perfect score on a speed test is a good way to spend a week on something worth less than fixing your shipping display.
8. Show the product properly
People cannot pick it up. Your images are doing that job.
Multiple angles. Scale shown against something familiar. Detail shots of the parts people worry about, which are usually the fastener, the seam, or the finish. Video helps for anything with movement or assembly. A 360-degree spin helps for shoes, bags, and hardware. It does nothing for a candle.
Write the details people search for. Dimensions, materials, weight, care instructions, what is in the box. Every unanswered question is a reason to close the tab.
9. Use reviews where the decision happens
Reviews work, and they work best next to the buy button rather than on their own page.
Show the unflattering ones too. A page with nothing but 5-star reviews reads as fake, and shoppers now look for the 3-star ones first to find out what is wrong with the product. Answering a bad review in public is worth more than hiding it.
Ask for reviews with an automated email after delivery, not at the moment they order. Nobody can review a thing they have not received.
10. Test, but test the things that matter
A/B testing is not a strategy. It is a way to settle arguments.
Do not run a test on button color when your shipping cost appears at step 4. Fix the known problems from the table at the top of this page first. Test the things you cannot reason your way through: which product goes on the landing page, what the offer is, how you describe the guarantee.
You also need enough traffic for a result to mean anything. Below a few hundred orders a month, most tests will tell you nothing, and acting on a false result is worse than not testing at all.
What conversion work cannot fix
Every tactic on this page makes a first order more likely. None of them make a second one more likely.
That is a different job, and for most stores it is the bigger one. You can spend a quarter lifting conversion from 2.1% to 2.4% and still have a business that has to buy every customer twice. The stores that get out from under rising ad costs are the ones where a meaningful share of revenue comes from people who already bought.
Conversion work and retention work also share a boundary, and it sits at the cart. Everything above is about removing the reason someone leaves. What happens after they leave is a different system: the abandoned cart flow, the checkout abandonment flow, and the post-purchase sequence that turns one order into a habit.
Fix the checkout first. Then build the flows.
Where to start this week
- Go through your own checkout on a phone and count the form fields
- Find the exact screen where shipping cost first appears
- Turn on guest checkout
- Move your reviews next to the buy button
That is a morning of work and it addresses the top 3 reasons people abandon. Everything else on this page can wait.
