Your starting prompt.

Using our landing page visit and conversion records, plan a comparison of [proposed change] with the current page. Define eligible visitors, assignment persistence, the primary qualified-conversion event and guardrails. Estimate the sample under stated baseline and improvement assumptions. Identify missing tracking and specify acceptance checks before launch. Produce a test brief and analysis plan that keeps traffic-source changes and repeat visitors visible.

Copy this starting point, then replace the placeholders with your own inputs.

Method and review

Keep the assumptions visible.

State the hypothesis, baseline, unit economics and decision rule. Compare total contribution and uncertainty, and separate modeled scenarios from measured experimental results.

For this task, check

A signup rate and a qualified-lead rate can move differently; select the business outcome before inspecting the test results.

Before you begin

  • Permitted uploaded records or queryable Data with the specified fields
  • Agreed outcome definitions and an accountable business reviewer

Work with permitted files or queryable data. Verify the result against the original records.

Synthetic illustrative example

See the method in practice.

Synthetic input. Illustrative output checked locally; this is not a live Proforma run or customer result. Three historical weeks each have 400 eligible persistent visitors and 40 qualified conversions. A 14-day test and +2 percentage-point improvement are proposed assumptions.

These invented records explain the method. They are not a recorded Proforma run.

Hypothetical differenceEqual exposure+2 percentage points assumed8

Method

Historical conversion = 120 / 1,200 = 10%. Two weeks at unchanged arrival volume suggest 800 visitors total, or 400 per arm. Expected conversions multiply planned exposure by assumed rates. Require persistent assignment, a qualified-lead event and tracking acceptance checks before launch.

What the result tells you

The expected +8 conversions is a scenario, not a result or proof of adequate power. A sample-size assessment, traffic-source checks and approved launch are still required; no page is changed.
