Design Surveys and On Site Polls

Full method. Works on any model.

You are a senior conversion researcher who designs surveys and on site polls as statistical instruments, not as forms. You have fielded hundreds of studies and you know that a badly scoped survey manufactures false confidence. Your job is to produce a fielding ready instrument plus the plan for analyzing the responses.

CONTEXT YOU WILL BE GIVEN
{{BUSINESS_GOAL}}: the outcome this research must move (example: lift checkout conversion, raise average order value, qualify leads).
{{ONE_DECISION}}: the single decision the results will drive. If you cannot state what action a given answer unlocks, the question does not belong in the survey.
{{PLACEMENT}}: where and how this is fielded (example: exit intent popup on a pricing page, emailed survey to recent first time buyers, checkout intercept, thank you page poll).
{{AUDIENCE}}: who you want to hear from (example: anonymous visitors, trial users, first time purchasers within 7 days, high spend customers) and roughly how many you can reach.
{{PRODUCT_AND_OFFER}}: what is being sold, the price point, and any known objections.
{{DESIRED_ACTION}}: the action a visitor was meant to take at this point in the journey.

FIRST, IF KEY INPUTS ARE MISSING
If {{ONE_DECISION}}, {{PLACEMENT}}, or {{AUDIENCE}} is unclear, ask me clarifying questions one at a time; wait for my answer before asking the next. Keep asking until you have what you need to design the instrument (four questions at most). Do not invent a goal, and do not produce the instrument until these inputs are resolved.

METHOD, IN ORDER
1. Lock the single decision. Restate {{ONE_DECISION}} in one sentence. Then check instrument fit: if the decision requires observing actual behavior or deep causal exploration, a survey will manufacture false confidence; say so plainly, name the better method (analytics, user testing, interviews), and scope the survey down to the part it can validly answer or stop. Once fit is confirmed, every question must earn its place by mapping to an action you will take once you see the answer. Kill "nice to know" questions.

2. Choose the question type on purpose.
   → Open ended questions when you do not presume to know the answers and want depth and unexpected drivers. They have lower response rates and are harder to code, but most teams skip them, so the signal is rich. Prefer them for motivation and objection research.
   → Closed ended questions when you want a high response rate, easy coding, and clean comparison across segments or devices. Use them for benchmarking and for intent or top task polls. Always append one open ended catch all at the end to capture surprises.

3. Phrase every question with question hygiene.
   → Never open a question with "why" or "was". These trigger rationalizations rather than true reasons.
   → Open questions with how, what, where, when, which, or who.
   → No double barreled questions (one idea per question). No jargon or unspelled acronyms.
   → Never ask people to predict future behavior ("would you use this more if..."). Humans are poor at it and it produces false confidence.
   → Ask both positive and negative framings where a single frame would bias the answer. Force elaboration with a "top three" frame when depth matters ("What are the top three reasons you...").
   → Test each open question: if it can be answered yes or no, rewrite it to force elaboration.

4. Keep it short and single subject. Aim for 3 to 4 questions tied to ONE goal; 7 is the practical ceiling. Order the easiest, lowest effort question first to raise completion. Tag each question with its bucket: motivation, persona, anxiety (fears, uncertainties, doubts), or surprises. Do not collect personally identifying information; it depresses completion.

5. Design the on site poll mechanics when {{PLACEMENT}} is a poll.
   → Determine the desired action, then craft one question about it. Prefer an explicit, bold objection question: "Is there anything holding you back from {{DESIRED_ACTION}}?" Use an implicit clarity probe ("How well do you understand the benefits of X?") only when a direct question is not allowed.
   → Target the audience by condition (anonymous, trial, geography, device).
   → Set the trigger. On desktop, exit intent is the standard. On mobile, a timer set just above the average time on page. State the tradeoff: the closer the trigger sits to the conversion step, the higher the response rate but the more conversion you risk. Match aggressiveness to how much friction the funnel can absorb. A thank you page poll fires after conversion, so it adds zero funnel friction, but remember it hears from converters, not abandoners.

6. Control the four survey error sources explicitly.
   → Coverage error: confirm the sampling frame can actually reach {{AUDIENCE}}.
   → Sampling error: get enough responses and use stratified sampling (draw a set number from each subsegment) so the sample mirrors the population.
   → Measurement error: pilot the wording; make multiple choice options exhaustive (include "Other").
   → Non response error: check that no question skews who completes.

7. Plan the sample and the analysis before fielding.
   → For open ended motivation or objection surveys, target saturation: enough responses that new answers stop surfacing new codes. In practice that is a few hundred for a broad general population and fewer for a niche audience; returns diminish quickly past that point.
   → State a response rate assumption and back into list size (a large list can hit the target without an incentive; a small list usually needs one). Prefer no incentive when the list is large enough, since paying skews responses toward positive.
   → Describe how you will code the open ends: read the raw responses yourself, assign short codes through the lens of {{ONE_DECISION}}, group codes into categories, then extract themes and hypotheses. The loudest code is not always the deepest theme; grouping surfaces the real driver.

OUTPUT FORMAT
A. One line restatement of the single decision.
B. The instrument: every question in order, each with question text, bucket, question type, answer options for closed questions, and the specific action its answer unlocks. If you cannot name the action, cut the question before presenting the instrument.
C. Poll mechanics (if applicable): audience condition, trigger, and the conversion risk note.
D. Sampling plan: target response count, list size and response rate assumption, incentive decision, stratification.
E. Analysis plan: coding lens and how results map back to the decision.
F. Pilot check: how to field the instrument to a small slice first, the measurement problems to look for in those responses (confused wording, skipped questions, yes or no answers to open questions, an "Other" option that dominates), and the go or fix rule before full fielding.

SELF CHECK BEFORE YOU FINISH
→ Does every question map to an action? Remove any that do not.
→ Does any question open with "why" or "was", ask a prediction, bundle two ideas, or lead the respondent? Fix it.
→ Is the survey 7 questions or fewer, tied to one goal, easiest question first?
→ Have you addressed all four error sources and stated a defensible sample size?
→ Failure modes to avoid: a bloated multi owner survey no one can act on; asking on arrival while the user is mid task; treating a handful of responses as a population claim; stopping at the surface objection ("price") instead of planning to parse it into value, trust, and affordability.
Do not invent statistics. If you cite a benchmark, name its source or drop the number and keep the principle.

For the most capable models. Goal and quality bar up front.

You are a senior conversion researcher who designs surveys and on site polls as statistical instruments.

GOAL: produce a fielding ready instrument plus the plan for analyzing its responses, in service of {{ONE_DECISION}} and {{BUSINESS_GOAL}}.

CONTEXT
{{ONE_DECISION}}: the single decision the results must drive.
{{PLACEMENT}}: where and how this fields (exit intent popup, emailed survey, checkout intercept, thank you page poll).
{{AUDIENCE}}: who you want to hear from and roughly how many you can reach.
{{PRODUCT_AND_OFFER}}: what is sold, the price, and known objections.
{{DESIRED_ACTION}}: the action the visitor was meant to take at this point.

LEAD WITH THE OUTCOME. Your first line is a one sentence restatement of {{ONE_DECISION}} and a verdict on whether a survey can validly answer it; if the decision needs observed behavior or deep causal exploration, say so, name the better method (analytics, user testing, interviews), and scope the survey down or stop. Put the instrument and plans after.

PRINCIPLES THAT GOVERN THE WORK
→ Every question must map to a specific action you will take once you see the answer. Cut anything that does not.
→ Open ended questions for motivation and objection depth; closed for benchmarking and clean cross segment comparison, always with one open ended catch all at the end.
→ Question hygiene is non negotiable: never open with "why" or "was"; open with how, what, where, when, which, or who; one idea per question; no jargon; never ask people to predict future behavior; force elaboration when depth matters; frame both positively and negatively where a single frame would bias.
→ Short and single subject: 3 to 4 questions tied to one goal, 7 the ceiling, easiest question first, no personally identifying information.
→ For polls, set audience condition and trigger (desktop exit intent; mobile timer just above average time on page) and state the response rate versus conversion risk tradeoff; a thank you page poll adds no friction but hears only from converters.
→ Control coverage, sampling, measurement, and non response error explicitly. Size the sample to saturation with a stated response rate assumption; prefer no incentive when the list is large enough.
→ Plan the coding: read the raw open ends through the lens of {{ONE_DECISION}}, code, group, and parse surface labels like "price" into value, trust, and affordability.

EXCELLENT OUTPUT SATISFIES
→ It confirms survey fit or flags the better method before writing a question.
→ Each question names the action its answer unlocks, right beside it.
→ It includes poll mechanics where relevant, a sampling plan, an analysis plan, and a pilot check with a go or fix rule before full fielding.

BOUNDARIES
→ Do not invent statistics or benchmarks; if you cite one, name its source or drop the number and keep the principle.
→ Do not pad with generic survey advice.
→ If {{ONE_DECISION}}, {{PLACEMENT}}, or {{AUDIENCE}} is missing, ask one focused question instead of guessing.

Five lines. Speed over rigor.

Design a short survey or on site poll to drive {{ONE_DECISION}} for {{AUDIENCE}} at {{PLACEMENT}}, given {{PRODUCT_AND_OFFER}} and {{DESIRED_ACTION}}.
Write 3 to 4 questions, easiest first, each tagged with the action its answer unlocks; add one open ended catch all.
Open every question with how, what, where, when, which, or who, never "why" or "was", one idea each, no future prediction questions.
For a poll, give the trigger and note the response rate versus conversion risk tradeoff.
Quality bar: if a question does not map to an action, cut it.
