Fix the bucket before you pour more in
When sales are flat, the instinct is to buy more traffic. But every visitor who reaches the checkout and leaves has already been paid for. Improving the last three screens of a store usually returns more than any ad campaign.
Open your own store on your phone, on mobile data, and try to buy something. Then work through this list.
Speed
1. Does the product page appear quickly on a phone connection? Test on a real device, not on office Wi-Fi. Large images and third-party scripts are the usual culprits — our Core Web Vitals guide covers how to find them.
2. Does anything jump while the page loads? A button that moves as you tap it is a lost sale and a mis-tap on something else.
3. Does "Add to cart" respond instantly? If nothing visibly happens, people tap twice — or leave.
The form
4. Can a customer check out without creating an account? Offer account creation after the order, when it costs them nothing.
5. Are you asking only for what you need? Every optional field is a reason to stop. If you do not ship physical goods, you may not need an address at all.
6. Do the right keyboards appear? Number pad for card and phone, email keyboard for email, and address autofill switched on. These are small HTML attributes with a large effect.
7. Are errors shown next to the field, in plain language? "Invalid input" at the top of the page helps nobody. Never clear a form because one field was wrong.
Payment and trust
8. Are the total, shipping and tax visible before the final step? A surprise at the last screen is the classic reason people abandon a cart.
9. Do you offer the payment methods your customers actually use? That includes wallets such as Apple Pay and Google Pay, and the local methods common in each country you sell to.
10. Are returns, delivery times and contact details easy to find? People look for them at the moment they hesitate.
Mobile
11. Can everything be done with one thumb? Buttons large enough to hit, nothing important hidden behind a hover, and the main action always in reach.
Recovery
12. What happens when a payment fails? The customer should stay on the same screen, with their details intact and a clear message about what to try next — not be sent back to an empty cart.
Then measure
Once the obvious problems are fixed, set up funnel tracking so you can see where people drop out: product page, cart, details, payment, confirmation. The step with the biggest drop is the next thing to work on. Without that data you are guessing.
If the checkout is slow or rigid because of the platform or theme underneath it, the fix may be structural — see Shopify, headless or custom for the options. Checkout audits and rebuilds are a regular part of our e-commerce development work.
