| Mechanism | Effect | Evidence |
|---|---|---|
| Processing animation | +10-20% CVR uplift | The "analysing your results" delay creates perceived effort/value. Users who see a processing step before results are significantly more likely to engage with the recommendation. Labour illusion effect (Norton, Buell 2011). |
| Price-after-value | +30% CVR uplift | Showing the personalised recommendation and match % before revealing price anchors the user on value rather than cost. Standard in quiz commerce (Care/of, Hims, Noom). |
| Gamification (scratch cards) | 7.17% CVR benchmark | Scratch-to-reveal mechanics exploit the variable reward loop. Used successfully by Spin-a-Sale, Wheelio, and similar Shopify apps. Effect is strongest for first-time visitors; repeat visitors show fatigue. |
| Personalisation language | +15-25% CTR on CTA | "Based on your [profile name] pattern" outperforms generic "Buy now". The Barnum effect (personal validation from general statements) drives engagement with the result. |
| Score/number | +12% engagement | Showing a numeric score (even somewhat arbitrary) gives users a concrete reference point. Score-based reveals have higher share rates than text-only results. |
| Fewer questions = higher completion | ~5% drop-off per question | Each additional question beyond 3 adds ~5% abandonment. The sweet spot for purchase-oriented quizzes is 3-5 questions. Below 3, perceived personalisation drops; above 6, completion suffers. |
| Cost comparison anchoring | +18-22% CVR for price-sensitive segments | Reframing cost as "less than your daily coffee" is the #1 converting price anchor in the supplement space. Particularly effective when the user self-identifies their current spending. |
| Pre-education (micro-content) | +8-15% CVR for considered purchases | Brief educational content before a quiz increases perceived expertise and trust. Particularly effective for science-backed products. Must be under 30 seconds total reading time or engagement drops. |
The dopamine keyword cluster represents the highest-volume, lowest-competition entry point for Brainzyme:
| Brand | Quiz Type | Questions | Reveal Mechanic | Differentiator |
|---|---|---|---|---|
| Care/of | Vitamin recommendation | ~12 questions | Personalised pack builder | Custom packs (high AOV) |
| Noom | Weight loss assessment | ~20 questions | Projected timeline | Long quiz = investment effect |
| Hims/Hers | Health assessment | 5-8 questions | Recommended treatment | Medical framing |
| Mind Lab Pro | None | — | — | No quiz (opportunity gap) |
| Hunter Focus | None | — | — | No quiz (opportunity gap) |
| Brainzyme | Dopamine symptom match | 2-4 questions | Scratch card / score ring | First nootropic quiz with neurotransmitter angle |
The traditional DTC supplement path (ad → product page → purchase) has a fundamental problem for considered purchases: the user must self-convince that the product is right for them. A quiz inverts this — the page tells the user why the product matches their specific situation, making the purchase feel like a natural next step rather than a leap of faith.
Key strategic advantages of the quiz approach:
The quiz is designed for a direct purchase conversion path (not lead magnet/nurture):
| Var. | Name | Hypothesis | Key Difference | Questions |
|---|---|---|---|---|
| A | Control — Scratch Card | Gamification (scratch-to-reveal) increases engagement and share rate, driving higher CVR | Canvas scratch card with confetti on reveal | 4 |
| B | Score-First (No Scratch) | Removing gamification reduces friction for serious buyers; the score ring alone provides sufficient engagement | Animated SVG ring gauge + counting number, no scratch card or confetti | 4 |
| C | VSL Hybrid (Pre-Education) | 3 educational insight cards before the quiz increase trust and perceived expertise, lifting CVR for considered purchases | 3 dopamine insight cards → 3 questions (not 4) → scratch card reveal | 3 + 3 insight cards |
| D | Comparison-Led (Cost Anchor) | Anchoring on existing daily spend (coffee/energy drinks) reframes FOCUS PRO as a savings, not an expense | Cost comparison cover, Q3 asks current focus method, reveals savings calculation | 3 |
| E | Ultra-Minimal (2 Questions) | Maximum completion rate from minimum friction; tests whether fewer questions outweighs reduced personalisation investment | Only 2 questions, no gamification, shortest possible path to recommendation | 2 |
Flow: Cover → Q1 (afternoon feeling) → Q2 (focus behaviour) → Q3 (desired outcome) → Q4 (frequency) → Analysis animation (4s) → Score counter + scratch card reveal → Product recommendation
Reveal mechanic: Canvas-based scratch card using globalCompositeOperation: 'destination-out'. When 35% of the surface is scratched, the card auto-clears with confetti animation, revealing the profile name and match %.
Profiles: 3 profiles (Low-Fuel, Scattered Signal, Burnout) mapped from Q1+Q2 answers, with severity boost from Q4 (+0/+3/+6).
Primary hypothesis: The scratch card creates a variable reward loop that increases engagement and emotional investment in the result.
Flow: Identical to A through analysis, then: SVG circular ring gauge fills over 2s while score counts up → Profile title + match % fade in below → CTA button appears.
What it tests: Whether the scratch card gamification is net positive or net negative. Some audiences (professionals, older demographics) may find scratch cards gimmicky. The ring gauge provides a "medical dashboard" aesthetic that may better match the science-backed positioning.
Risk: Lower engagement/share rate if the gamification was driving social sharing. Mitigated by the score still providing a shareable number.
Flow: Cover → 3 insight cards (dopamine facts, each 1-2 sentences) → Q1 → Q2 → Q3 → Analysis → Scratch card reveal → Recommendation.
What it tests: Whether brief education before the quiz increases trust, perceived expertise, and ultimately CVR. The insight cards prime the user to understand WHY dopamine matters, making the quiz results feel more credible.
Trade-off: Longer total path (3 extra taps) may increase drop-off. Compensated by dropping Q4, keeping total interactions equal to Variation A (7 taps for both). If pre-education works, it could justify a full "dopamine guide" lead magnet funnel later.
Flow: Cost comparison cover (coffee vs FOCUS PRO) → Q1 → Q2 → Q3 (current focus method) → Analysis → Score ring + personalised savings callout → Recommendation with savings row.
What it tests: Whether price anchoring on the cover screen increases purchase intent. Q3 is replaced with a "what do you currently use?" question that feeds a dynamic savings calculation in the reveal.
Best for: Price-sensitive segments, Google Ads targeting cost-comparison keywords ("cheap focus supplements", "best value nootropics").
Risk: May attract bargain-hunters with lower LTV. The cost framing could also cheapen perceived quality. Monitor AOV alongside CVR.
Flow: Cover ("2 Questions. Your Personalised Focus Plan.") → Q1 (focus challenge, 4 options mapping directly to profiles) → Q2 (urgency, maps to severity) → Short analysis (2s) → Minimal reveal (profile + match + CTA, no gamification) → Recommendation.
What it tests: Whether radical simplicity beats engagement depth. The hypothesis: if 80% of users who start a 4-question quiz complete it, nearly 95% would complete a 2-question quiz. The question is whether that higher completion compensates for lower perceived personalisation.
Best for: Mobile traffic, high-bounce keywords, retargeting (users who already know the brand).
Risk: Result feels too generic, reducing trust in the recommendation. 2 questions may not create enough "investment" for the commitment/consistency effect to drive purchase.
Since these are standalone HTML pages on GitHub Pages (not Shopify), A/B testing is done at the ad level, not with a JS-based split testing tool:
/dopamine-quiz/ vs /dopamine-quiz/variation-b.html)Run tests sequentially, not all at once, to maintain statistical power:
| Round | Test | Duration | Why This Order |
|---|---|---|---|
| 1 | A (scratch card) vs B (score ring) | 2-3 weeks | Tests the single biggest variable: gamification. Winner becomes the new control for Round 2. |
| 2 | Round 1 winner vs E (2-question minimal) | 2-3 weeks | Tests question count. Determines optimal quiz length before testing content changes. |
| 3 | Round 2 winner vs C (pre-education) vs D (cost anchor) | 3-4 weeks | Tests content/framing variations. Needs more traffic due to 3-way split. |
| Variation | Primary Hypothesis | Primary Metric | Expected Direction |
|---|---|---|---|
| A (Control) | Scratch card gamification maximises engagement | Quiz-to-purchase CVR | Baseline |
| B | Removing gamification increases trust for serious buyers | Quiz-to-purchase CVR | Higher CVR for 35+ demographic, lower for 18-25 |
| C | Pre-education increases perceived expertise and trust | Quiz-to-purchase CVR | Higher CVR but lower completion rate (net effect unclear) |
| D | Cost anchoring reframes purchase as savings | Quiz-to-purchase CVR | Higher CVR from price-sensitive segments |
| E | Radical simplicity maximises completion rate | Completion rate × CVR (composite) | Highest completion, possibly lower per-completion CVR |
| Metric | Definition | Target |
|---|---|---|
| Quiz completion rate | % of users who reach the recommendation screen after starting | ≥80% |
| Click-through rate (CTR) | % of recommendation viewers who click "Get FOCUS PRO" | ≥40% |
| Quiz-to-purchase CVR | % of quiz starters who complete a purchase on Shopify | ≥5% |
| Email capture rate | % of recommendation viewers who submit email | ≥30% |
| CPA from quiz | Ad spend / purchases attributed to quiz page | ≤£15 |
| Metric | Definition | Why It Matters |
|---|---|---|
| Time on page | Median seconds from page load to exit | Indicates engagement quality; too short = bounce, too long = confusion |
| Drop-off by screen | % exiting at each quiz screen | Identifies which question or step causes abandonment |
| Bundle vs single CTR | Ratio of bundle clicks to single product clicks | Indicates upsell effectiveness of the "Try All 3" CTA |
| Profile distribution | % of users in each profile (Low-Fuel, Scattered, Burnout) | If one profile dominates (>60%), questions may not be differentiating well |
For a two-variant test (A vs B) with:
Required: ~4,800 quiz starters per variation (9,600 total for a 2-way test).
At an estimated 200-500 quiz starts/day (depending on ad spend), each 2-way test needs 10-24 days of traffic.
For a 3-way test (Round 3), multiply by 1.5x: ~7,200 per variation, ~21,600 total, ~15-36 days.
