# CRO Methodology

Scientific, customer-centric approach to conversion rate optimization based on the CRE Methodology(TM). Extraordinary improvements come from understanding WHY visitors don't convert, not from copying competitors or applying generic tips.

## Core Principle

**Don't guess -- discover.** Every visitor who doesn't convert has a reason. Discover those reasons through research, then systematically eliminate them with evidence and proof. This evidence-based approach consistently outperforms "best practices", intuition, competitor copying, and expert opinion.

## Scoring

**Goal: 10/10.** Rate any landing page, funnel, or conversion flow 0-10 against the principles below. Report the current score and the specific improvements needed to reach 10/10.

## The CRO Frameworks

### 1. The CRO Process

**Core concept:** A systematic 9-step process moving from defining success metrics through research and experimentation to scaling wins across the business.

**Why it works:** Random optimization skips research. The process forces you to understand visitors before changing anything, so every change rests on evidence, not opinion.

**Key insights:**
- Define success metrics aligned with business KPIs before touching any page
- Map the entire funnel to find "blocked arteries" (high-traffic underperforming paths) and "missing links" (absent funnel stages)
- Research visitors in three dimensions: who they are, what blocks them (UX problems), what stops them (objections)
- Gather market intelligence from competitors, reviews, and other industries
- Prioritize ideas with ICE scoring; design bold experiments, not "meek tweaks"
- Run experiments with statistical rigor (95% confidence minimum, full business cycles), then scale wins across the business

**Product applications:**

| Context | CRO Process Step | Example |
|---------|-----------------|---------|
| **Landing page audit** | Define goals, map funnel, research visitors | 70% bounce because value prop is unclear |
| **Checkout optimization** | Map funnel for blocked arteries | Shipping cost shock causes 40% cart abandonment |
| **Email sequence** | Scale wins | Winning objection-handling copy reused in drip emails |

**Copy patterns:**
- "What's preventing you from [action] today?" (exit survey to discover objections)
- "Here's what [X] customers found..." (counter-objection with social proof)
- Hypothesis template: "If we [change X], then [metric Y] will improve because [reason from research]"

**Ethical boundary:** Never manipulate test results or cherry-pick data; report all tests, including failures.

See: [testing-methodology.md](references/testing-methodology.md) for ICE scoring, A/B vs. multivariate guidance, and statistical rigor.

### 2. Customer Research & Objections

**Core concept:** Visitors fail to convert for specific, discoverable reasons. Exit surveys, chat logs, support tickets, sales calls, and reviews reveal the "voice of the customer" and their real objections.

**Why it works:** Teams' guesses about why visitors leave are almost always wrong. Research uncovers objections no one anticipated, and the customer's own language out-persuades any copywriter's invention.

**Key insights:**
- Primary sources (exit surveys, live chat, tickets, sales calls) give direct visitor language; secondary sources (reviews, social media, competitors) reveal industry-wide objections
- The "Big 5" universal objections: Trust, Price, Fit, Timing, Effort
- Quantitative research (analytics, heatmaps) shows WHERE problems are; qualitative (surveys, interviews) shows WHY
- Non-converter surveys should ask ONE question for maximum response; post-purchase surveys ("What almost stopped you from buying?") reveal the objections that matter most

**Product applications:**

| Context | Research Method | Example |
|---------|---------------|---------|
| **Exit intent** | On-site survey | "What's preventing you from signing up today?" |
| **Post-purchase** | Email survey within 7 days | "What almost stopped you from buying?" |
| **Objection mining** | Support tickets + reviews | Search "but", "however", "worried about"; negative reviews = unaddressed objections |

**Copy patterns:**
- Use exact customer language in headlines and body copy -- it outperforms polished marketing copy
- "What's the one thing we could change to make you [action]?"
- "How would you describe [product] to a friend?" (reveals positioning in customer terms)

**Ethical boundary:** Anonymize data, get consent for recordings, and don't survey so aggressively that you degrade the experience.

See: [RESEARCH.md](references/RESEARCH.md) for tools, survey questions, and data analysis methods.

### 3. Persuasion Assets

**Core concept:** Every company sits on overlooked proof -- undisplayed testimonials, unmentioned awards, hidden credentials, buried guarantees. Inventory these "persuasion assets", acquire missing ones, display them.

**Why it works:** Visitors decide on evidence, not claims. A modest claim with overwhelming proof beats a bold claim with none.

**Key insights:**
- Audit five categories: Credentials & Authority, Social Proof, Risk Reversal, Data & Specificity, Process & Methodology
- Create a wish list for missing assets and actively acquire them (request testimonials, apply for awards, compile statistics)
- "Proof sandwich" structure: Claim (bold promise), then Proof (evidence), then Reinforcement (secondary proof)
- Proof hierarchy, strongest first: specific results with context > named testimonials with photos > case studies > statistics > logos > generic testimonials
- Place proof at points of friction, not in FAQs; specific numbers beat round ones ("47,832 customers" beats "About 50,000")

**Product applications:**

| Context | Persuasion Asset | Example |
|---------|-----------------|---------|
| **Landing page header** | Logo bar + rating | "Trusted by 10,000+ companies" with 5 recognizable logos |
| **Pricing page** | Risk reversal | "30-day money-back guarante
