The case for autocomplete is grounded in checkout data. The address step is one of the slowest, most error-prone parts of a form — and one of the most impactful to optimise.
The numbers that move
How to measure your own uplift
- Baseline checkout completion rate before launch
- Time spent on the address step
- Address error and correction rate
- Failed-delivery and address-change support volume
Put it to the test
Add lookup with the address autocomplete API and read the mechanics in autocomplete & conversion rate. Back to the checkout hub.
Frequently asked questions
How much does address autocomplete improve conversion?
Results vary by store, but reducing the address step to a single search consistently cuts form time and errors, improving checkout completion — especially on mobile where typing friction is highest.
What metrics show autocomplete ROI?
Track checkout completion rate, address-step time, address error/correction rate, and failed-delivery volume before and after enabling autocomplete.
Is autocomplete worth it for small stores?
Yes — even modest uplifts in completion plus fewer failed deliveries typically outweigh the low per-lookup cost.
