Three things every checkout should do before you optimize anything
Before you A/B test button colors, get the fundamentals right: page weight, address autofill, and a payment method customers actually want to use.
Most checkout teardowns we run end the same way: the team is debating button copy, and the real issue is that the page takes four seconds to interactively respond to a click.
Before you A/B test anything on checkout, get these three right.
1. Page weight
A checkout that takes more than two seconds to become interactive on a mid-tier mobile network is leaving conversion on the table. The fix is usually obvious once you look — third-party analytics scripts, an over-eager chat widget, fonts that block render.
2. Address autofill
If your address field doesn’t accept the browser’s saved address with one tap, you’ve added five seconds of typing for every customer. This is one of the highest-ROI fixes available and takes about an hour.
3. The right payment methods
In some markets, offering only cards costs you 15–30% of potential revenue. Look at where your customers are. If a meaningful share are in regions that prefer wallets or local rails, add them through payment options.
If you’re using Plandalf hosted checkout, the first two are handled by default and PayPal slots in alongside Stripe with a couple of clicks.
