Perry Marshall — 80/20 Curve + Audience Targeting
Positioning: Author of 80/20 Sales and Marketing. The modern authority on Pareto thinking applied to marketing. Also Google/Meta ads authority (Ultimate Guide to Google Ads).
The Core Framework: The 80/20 Curve (Fractal Pareto)
Inside any market, 80% of the revenue comes from 20% of the buyers. But that 20% is itself a market — and inside it, 80% of THE revenue comes from 20% of THOSE buyers. The curve continues infinitely (fractal).
Implication: most marketers average across the whole audience. The winner targets the top slice, designs for them, and collects disproportionate revenue.
The 80/20 Calculator (mental model)
| If you have… | Then the top 20% delivers… |
|---|---|
| 100 prospects | ~64% of revenue |
| 100 prospects → top 20 | Of those 20, top 4 deliver ~51% of revenue |
| → top 4 | Of those 4, top 1 delivers ~41% of revenue |
The mathematical consequence: your single most valuable customer is worth more than hundreds of marginal ones. Design the offer and message for THAT buyer first.

Step 2 — Audience Profile:
When writing the avatar, don’t average. Ask:
- If I had only 10 students, which profile would I pick?
- Of that 10, which 2 would I most want to keep?
- Of those 2, who is the ONE?
That ONE person is the avatar. The Marketing Statement speaks to them specifically. Everyone else who ALSO fits comes along for the ride — but design for the top 1%.
Concrete HK application:
- If the course is for “40-50 歲職場人士想轉行”, don’t average. Pick: “45歲企業中層管理，供緊 2 個仔女書簿費，太太係全職家庭主婦，手上有 HK$300K 流動資金，對 AI 又怕又想入，唔想丟飯碗但又想開個副業”
- Everything (price, bonus, tone, proof) is designed for THIS person
- Other similar buyers will still convert — but this one converts first and pays most
Step 6 — Pricing Tier Decision:
80/20 principle for pricing: in any niche, the top 20% of price points capture 80% of profit. A HK1,980 course with 6× the students, because support cost and refund rate concentrate at low price.
Decision rule: unless there’s a strong reason otherwise, price toward the HIGHER end of market-appropriate tier. Refunds, complaints, and support costs decrease proportionally. High-ticket buyers are also more likely to refer.
The “Racking” Technique — Segmenting with 80/20
Before writing copy, rack your market into 5 piles by commitment level:
| Rack | Who | How Many | Priority |
|---|---|---|---|
| 1 | Tire-kickers / curious but won’t buy | 40% | Ignore |
| 2 | Interested but not ready (timing / budget) | 30% | Nurture list |
| 3 | Warm — ready if offer is right | 15% | Primary target |
| 4 | Hot — looking to buy NOW | 10% | Close immediately |
| 5 | Rabid fans / repeat buyers | 5% | Upsell / ambassador |
Strategy decisions:
- Cold traffic ads target Rack 3 (not 1 or 2 — you’ll attract tire-kickers)
- Webinar / VSL targets Rack 3 and converts to Rack 4
- Close in the webinar = Rack 4
- Follow-up sequences move Rack 2 to Rack 3 over time
- Rack 5 is for backend (higher-ticket program, mastermind)
Decision Aid — 80/20 Sanity Check
Before finalising the strategy:
- Can I name the ONE avatar (not a range)?
- Is the price set for the top-20% buyer, not the average?
- Am I designing for Rack 3 (warm) or wasting energy on Rack 1 (tire-kickers)?
- Does the offer have a natural upsell path for Rack 5?
When to Reference This File
- Step 2 — when audience feels too broad
- Step 6 — when pricing feels arbitrary
- When reviewer says “we want to reach more people” — push back with the curve
