Most conversion advice is a pile of tips with no ranking, so teams burn weeks A/B testing button colors while their checkout leaks money on mobile. Conversion optimization works when you fix the biggest leaks first. This is the order we'd actually work in — highest revenue impact at the top, vanity tweaks at the bottom.
1. Fix checkout friction first
Checkout is where intent turns into revenue, and where most of it dies. Every extra field, forced account creation, or surprise cost at the last step sheds buyers who were ready to pay.
- Offer guest checkout — never force account creation before purchase.
- Show total cost, including shipping, as early as possible. Surprise fees are the top abandonment cause.
- Support Apple Pay, Google Pay, and Shop Pay so returning buyers skip the form entirely.
- Keep it to as few steps as the flow allows, with a visible progress indicator.
This is almost always the single highest-leverage area. Start here.
2. Make the store fast
Speed is conversion. A store that takes several seconds to become interactive loses buyers before they see a product. Chase Core Web Vitals — LCP, INP, CLS — as a revenue metric, not a technical one.
Compress and lazy-load images, ship less JavaScript, and serve from a CDN. On mobile especially, every second of load time is measurable lost revenue.
3. Earn trust above the fold
Shoppers decide fast whether a store is legitimate. Reduce that friction:
- Real product photography and clear, honest descriptions.
- Reviews and ratings on product pages.
- Visible return policy, shipping timelines, and support contact.
- Security and payment badges near the buy button.
Trust signals don't feel like CRO, but they move the numbers.
4. Design for the thumb
Most traffic is mobile, yet many stores are still designed desktop-first. Tap targets should be large, the add-to-cart button should stay reachable, and forms should use the right mobile keyboards. Test the entire purchase on a real phone, on real mobile data — not just a resized browser window.
5. Recover the carts you lose
Not every abandonment is preventable. Win some back with automated abandoned-cart emails and, where appropriate, exit-intent offers. A well-timed reminder recovers a meaningful slice of otherwise-lost orders at almost no cost.
Measure like it's revenue, not opinions
Instrument the funnel — product view, add to cart, checkout start, purchase — so you can see exactly where buyers drop. Change one thing, measure the segment it affects, and keep what wins. Optimization without measurement is just redecorating.
At Doktouri we treat conversion as an engineering problem: measurable, testable, and tied to revenue. If your store gets traffic but not enough orders, let's talk.
