12 eCommerce changes that actually move the conversion needle
We've run hundreds of experiments across eCommerce stores. These are the 12 changes that consistently improved conversion — with data to back it up.
We track everything. Over several years of running eCommerce programmes, certain changes have proven reliably effective across different brands, markets, and product categories. These aren't universal laws — test everything on your own store — but they're where we start.
Show products in real context
User-generated photos and lifestyle imagery consistently outperform studio shots in A/B tests. People want to see the product in a setting that looks like their life. Add a section for customer photos to every product page — it doesn't need to be polished.
Put social proof next to the buy button
Star ratings, review counts, and recent purchase signals ("24 people bought this this week") belong immediately adjacent to the Add to Cart button — not hidden below the fold in a reviews tab. Proximity is everything.
Fix your size/variant selectors
Poorly designed variant selectors (tiny radio buttons, unclear sizing guides, out-of-stock variants that aren't clearly indicated) are silent conversion killers. Every variant selection that confuses a customer is a lost sale.
Show shipping cost and timeline on the product page
The number one reason for cart abandonment is "unexpected costs at checkout." Show shipping cost (or free shipping threshold) and delivery estimate directly on the product page. Remove the uncertainty before it becomes abandonment.
Sticky Add to Cart on mobile
On mobile, users scroll. If the Add to Cart button scrolls off screen, you're creating friction. A sticky CTA bar on mobile — appearing after the primary button scrolls out of view — consistently lifts mobile conversion 10–20%.
Kill the account wall
Forcing account creation before checkout is one of the most expensive UX mistakes in eCommerce. Always offer guest checkout. You can invite account creation post-purchase, when the customer already trusts you.
Reduce checkout steps
Every additional step in checkout increases abandonment. Autofill, address lookup APIs, single-page checkout layouts — these aren't nice-to-haves. In our testing, reducing from 3-step to 1-page checkout lifts completion rates 15–25%.
Add a visual progress indicator
For multi-step checkouts you can't eliminate, a clear progress bar ("Step 2 of 3") reduces abandonment by setting expectations. People abandon when they don't know how much further they have to go.
Trust signals at the payment step
Security badges, payment method icons, your returns policy, and a phone number or chat option — these belong at the payment step, where purchase anxiety peaks. Add them directly above the "Place Order" button.
Build your abandoned cart sequence properly
Three-email abandoned cart sequences consistently outperform single emails. Email 1: 1 hour after abandonment (reminder, no discount). Email 2: 24 hours (address the most common objection — size? returns?). Email 3: 72 hours (offer, if you use discounts at all).
Mobile-first everything
If you're not designing and testing on mobile first, you're optimising for the minority. For most DTC brands, 65–75% of traffic is mobile. If your mobile conversion rate is less than half your desktop rate, you have a mobile problem, not a conversion problem.
Measure page speed as a conversion metric
For every 100ms of additional load time, conversion rate drops 1–2%. A 3-second page is not a technical problem — it's a revenue problem. LCP should be on your weekly conversion dashboard alongside CVR and AOV.
One more thing: prioritise correctly
Don't try to implement all 12 at once. Prioritise by impact × ease. Sticky mobile CTA and guest checkout are high-impact, low-effort. Social proof placement is high-impact, medium-effort. Start there. Build a testing cadence, measure properly, and compound improvements over time.
