Most e-commerce teams over-think CRO. Before you build a complex experimentation program, ship these 12 well-known tests — they reliably move revenue and cost very little to try.
Key takeaways
- Speed is a feature; sub-2s LCP changes conversion math.
- Trust badges and reviews are still under-used on PDPs.
- Reduce checkout friction before you discount.
- Test one variable at a time, then layer wins.
01
PDP — Product detail page
Your PDP is the highest-leverage page on the site. Start here.
- Sticky add-to-cart on mobile
- Reviews above the fold with star summary
- Real shipping ETA, not 'usually ships in 1–3 days'
- Pay-later option (Klarna / Afterpay) on the price line
02
Cart and checkout
Most stores leak 60%+ at checkout. Each of these typically recovers 1–4 points of conversion.
- Express checkout (Apple/Google Pay) at the top
- Guest checkout, with optional account creation post-purchase
- Single-page checkout for orders under $100
- Trust block: returns, secure-pay, support, all visible
03
Site-wide trust and speed
Hard wins that compound across every page.
- LCP under 2.0s on mobile
- Visible support contact in the header
- Free-shipping threshold in the announcement bar, updated dynamically by cart value
- Order tracking accessible without an account
Wrapping up
Run them in this order, give each test 2 weeks of real traffic, and stack the winners. Most stores find 8–15% blended conversion lift in a quarter.
