Prompt
Act as a UX and conversion rate optimization (CRO) specialist for e-commerce.
Store: {{store}}, which sells {{products}}.
Platform: {{platform}}.
Current checkout, step by step: {{current_checkout}}.
Available data: {{data}}.
Main market: {{market}}.
Deliver, in this order:
1. A map of the current checkout with every step, the fields requested and the decisions the user makes.
2. A heuristic audit per step: issues found, severity (critical, high, medium or low) and the evidence or principle behind each one (cognitive load, surprise costs, trust, forced account creation, form validation, mobile usability, accessibility).
3. If funnel data exists, identify the step with the biggest drop-off and suggest hypotheses that explain it. If not, list which analytics events to track.
4. An improved checkout proposal: steps, order and fields, with real microcopy for buttons, errors and trust messages.
5. Recommended payment and shipping options for the stated market, and why.
6. A prioritization table (impact, effort, confidence) and the first five changes you would make.
7. An A/B test plan for the top improvement: hypothesis, primary metric, guardrail metrics and a rough sample size.
Constraints:
- Do not invent conversion figures or industry statistics: any reference you cite must be verifiable; otherwise mark it as [VERIFY].
- Prioritize mobile.
- State which changes {{platform}} supports natively, which need an app or plugin and which need custom development.
- If you are missing information about any step, ask me.How to use it
- Walk through your checkout on a phone and note every screen and field.
- If you have Google Analytics or platform reports, add the drop-off rate per step.
- Start with the high-impact, low-effort fixes.
- Validate major changes with an A/B test before rolling them out to all traffic.
Usage example
Store: Alba Skincare · Products: natural skincare · Platform: Shopify · Abandonment: 72% between cart and payment.
Sample output
2. Heuristic audit (excerpt)
| Step | Issue | Severity | Principle |
|---|---|---|---|
| Forced sign-up | Requires an account before showing shipping | Critical | Forced account creation, friction |
| Address | No autocomplete or proper mobile keyboard | High | Mobile usability |
| Shipping | Cost appears late | High | Surprise costs |
| Payment | Card only | High | Trust and payment preferences |
3. Biggest drop-off
The 72% drop-off sits between cart and payment, exactly where forced sign-up and shipping cost appear. Hypothesis: someone buying a gift on their phone doesn't want to create an account.
4. Proposed checkout (mobile first)
- Cart with estimated shipping shown.
- Email + address as a guest. Button: "Continue to shipping".
- Shipping and payment on one screen. Button: "Pay $34.90" (sample amount).
- Confirmation with "Create your account in one tap".
Sample error: "Please check the ZIP code: it should have 5 digits."
5. Payments for the US
Cards, Shop Pay, PayPal and Apple Pay / Google Pay [VERIFY availability on your Shopify plan]…
