| 3 | Expert performance marketing guidance for paid acquisition, conversion rate optimization, and data-driven growth — from ad creative to attribution modeling. |
| 4 | |
| 5 | ## Philosophy |
| 6 | |
| 7 | Great performance marketing is a system, not a series of tactics: |
| 8 | |
| 9 | 1. **Measure what matters** — Vanity metrics kill budgets |
| 10 | 2. **Test with intention** — Random A/B tests waste time and traffic |
| 11 | 3. **Optimize the full funnel** — A great ad to a bad landing page burns money |
| 12 | 4. **Compound learnings** — Every test teaches something for the next |
| 13 | |
| 14 | ## How This Skill Works |
| 15 | |
| 16 | When invoked, apply the guidelines in `rules/` organized by: |
| 17 | |
| 18 | - `paid-*` — Paid advertising strategy, creative, and copy |
| 19 | - `landing-*` — Landing page optimization |
| 20 | - `testing-*` — A/B testing and experimentation frameworks |
| 21 | - `analytics-*` — Attribution, CAC/LTV, and conversion tracking |
| 22 | - `budget-*` — Budget allocation and scaling |
| 23 | |
| 24 | ## Core Frameworks |

| 44 | ### The CAC/LTV Equation |
| 45 | |
| 46 | | Metric | Formula | Target | |
| 47 | |--------|---------|--------| |
| 48 | | **CAC** | Total Acquisition Cost / New Customers | Lower is better | |
| 49 | | **LTV** | Avg Revenue × Avg Lifespan | Higher is better | |
| 50 | | **LTV:CAC** | LTV / CAC | 3:1 or higher | |
| 51 | | **Payback Period** | CAC / Monthly Revenue | < 12 months | |
| 52 | |
| 53 | ### Funnel Math |
| 54 | |
| 55 | ``` |
| 56 | Impressions × CTR = Clicks |
| 57 | Clicks × CVR = Conversions |
| 58 | Conversions × Close Rate = Customers |
| 59 | Customers × ARPU = Revenue |
| 60 | ``` |
| 61 | |
| 62 | ### Channel Selection Matrix |
| 63 | |
| 64 | | Channel | Best For | Typical CAC | Intent Level | |
| 65 | |---------|----------|-------------|--------------| |
| 66 | | **Google Search** | High-intent capture | $50-200 | High | |
| 67 | | **Google Display** | Retargeting, awareness | $20-80 | Low | |
| 68 | | **Meta (FB/IG)** | B2C, visual products | $30-100 | Medium | |
| 69 | | **LinkedIn** | B2B, enterprise | $100-500 | Medium-High | |
| 70 | | **Twitter/X** | Tech audiences, awareness | $40-150 | Low-Medium | |
| 71 | | **TikTok** | Gen Z, viral potential | $20-60 | Low | |
| 72 | |
| 73 | ## Key Metrics by Stage |
| 74 | |
| 75 | | Stage | Primary Metric | Secondary Metrics | |
| 76 | |-------|---------------|-------------------| |
| 77 | | **Awareness** | Impressions, CPM | Frequency, Reach | |
| 78 | | **Interest** | CTR, CPC | Time on site, Bounce rate | |
| 79 | | **Consideration** | Conversion rate | Micro-conversions, Scroll depth | |
| 80 | | **Purchase** | CPA, ROAS | AOV, Conversion value | |
| 81 | | **Retention** | LTV, Repeat rate | NPS, Churn rate | |
| 82 | |
| 83 | ## Budget Allocation Framework |
| 84 | |
| 85 | ### The 70-20-10 Rule |
| 86 | |
| 87 | - **70%** — Proven channels and campaigns (scale what works) |
| 88 | - **20%** — Optimization tests (improve what's working) |
| 89 | - **10%** — Experimentation (test new channels/approaches) |
| 90 | |
| 91 | ### Scaling Checklist |
| 92 | |
| 93 | Before scaling a campaign: |
| 94 | - [ ] LTV:CAC ratio ≥ 3:1 |
| 95 | - [ ] Consistent performance over 2+ weeks |
| 96 | - [ ] Statistical significance on key metrics |
| 97 | - [ ] Landing page handles traffic spikes |
| 98 | - [ ] Tracking verified on all conversion events |
| 99 | |
| 100 | ## Anti-Patterns |
| 101 | |
| 102 | - **Scaling too fast** — Doubling budget overnight breaks algorithms |
| 103 | - **Testing everything at once** — Can't learn what caused the change |
| 104 | - **Ignoring attribution** — Last-click lies, multi-touch tells the truth |
| 105 | - **Copy-paste ads** — Same creative across channels fails |
| 106 | - **Optimizing for clicks** — Clicks don't pay bills, conversions do |
| 107 | - **Set and forget** — Ads fatigue, audiences shift, competition changes |
| 108 | - **Vanity metrics** — Impressions feel good, revenue feels better |
