CRO Methodology
Scientific, customer-centric approach to conversion rate optimization based on the CRE Methodology™.
Core Philosophy
Don't guess—discover. The methodology rejects "best practices" and "magic buttons" in favor of evidence-based optimization. Extraordinary improvements come from understanding WHY visitors don't convert, not from copying competitors or applying generic tips.
The 9-Step CRE Process
1. Define Success Metrics
Align goals with business KPIs. Don't jump to testing—first understand what success looks like. Identify which metrics actually matter (revenue, not just clicks).
2. Map the Conversion Funnel
Visualize every step from first impression to thank-you page. Identify:
- Blocked arteries: High-traffic paths with underperformance
- Missing links: Gaps in the funnel (no referral program, no email sequence, no upsells)
3. Understand Visitors (The Critical Step)
Answer: "Why aren't visitors converting?" Research in three areas:
a) Visitor types & intentions
- New vs. repeat visitors
- Traffic source behavior
- Buyer journey stage
- Intent signals
b) UX problems (willing but unable)
- Browser compatibility
- Page speed
- Navigation clarity
- Form usability
- Error messages
c) Objections (able but unwilling)
Use surveys, chat logs, support tickets to capture the "voice of the customer." See OBJECTIONS.md for O/CO framework.
4. Gather Market Intelligence
- Analyze competitors
- Monitor social media, reviews
- Transfer winning strategies from other industries
- Identify positioning opportunities
5. Find Hidden Persuasion Assets
Every company has overlooked proof elements:
- Testimonials not displayed
- Awards not mentioned
- Statistics not highlighted
- Guarantees not prominent
- Team credentials hidden
Create a "wish list" of assets to acquire.
6. Create Experimental Strategy
Prioritize ideas using three criteria:
1. Impact potential: Could this double conversion rate?
2. Ease of implementation: Quick wins first
3. Proven success: Has this worked before?
Critical: Make BOLD changes, not "meek tweaks." Small changes rarely reach statistical significance and waste resources.
7. Design Challengers
Create wireframes based on research insights (not guesswork). Focus on:
- Headlines
- Introductory paragraphs
- Calls-to-action
- Objection handling
See COPYWRITING.md for persuasion techniques.
8. Run Experiments
Use A/B testing platforms (Optimizely, VWO, etc.). For each test:
- Document hypothesis
- Define success metrics
- Wait for statistical significance
- Promote winners to new control
9. Scale Wins
Apply insights across:
- Other landing pages
- Ad copy
- Email sequences
- Offline materials
- Affiliate programs
Quick-Start Checklist
When optimizing any page:
- [ ] What is the ONE action visitors should take?
- [ ] Who are the visitors? What stage of buying journey?
- [ ] What are their top 3-5 objections? (Don't guess—research)
- [ ] What proof/counter-objections address each?
- [ ] Is the value proposition crystal clear in 5 seconds?
- [ ] Are there UX blockers? (speed, mobile, forms)
- [ ] What persuasion assets are missing or hidden?
Key Frameworks
- O/CO Table: Objection/Counter-Objection mapping. See OBJECTIONS.md
- Persuasion Assets: Proof elements inventory. See PERSUASION.md
- Funnel Analysis: Blocked arteries & missing links
- Bold vs. Meek: Test big changes, not button colors
Anti-Patterns (What NOT to Do)
- Copy competitors blindly
- Test button colors before understanding objections
- Assume you know why visitors leave
- Use "best practices" without validation
- Make changes based on HiPPO (Highest Paid Person's Opinion)
- Optimize individual pages without funnel context
- Give up after one failed test
