Strategies: Conversion Optimization

Guides conversion rate optimization (CRO): increasing the percentage of visitors who complete desired actions. Higher conversion rates mean increased revenue, reduced CAC, and better ROI. Use this skill when optimizing funnels, running experiments, or reducing friction on high-traffic pages.

When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.

Initial Assessment

Project context: Read root contextus.md when present and load only the modules relevant to this task. Without Contextus, use available project material or user-provided facts and ask for missing information; do not create a parallel context system.

Identify:

  1. Funnel stage: Awareness, consideration, decision, post-purchase
  2. Conversion goal: Signup, purchase, download, demo request
  3. Traffic: Volume; mobile vs desktop split
  4. Current conversion rate: Baseline for improvement

CRO Process

Step Action
1. Research Map funnel; identify high-traffic, low-conversion pages
2. Hypothesize Form testable hypothesis (if X, then Y because Z)
3. Prioritize Score by Potential, Importance, Ease (PIE)
4. Test A/B or multivariate; adequate sample size
5. Analyze Statistical significance; implement winner

PIE Prioritization Framework

Score each test idea 1–10:

Factor Question
Potential How much improvement is possible?
Importance How much traffic does this page get?
Ease How easy to implement?

Rank backlog by total score; run highest-impact tests first.

A/B Testing Best Practices

Practice Guideline
Sample size Calculate minimum before launch; 95% significance without adequate sample = false positives
Duration Run full week cycles; account for day-of-week effects
One variable Test one element per experiment (or use MVT for multiple)
Mobile separate Mobile converts ~50% of desktop; test mobile independently—thumb reach, form complexity differ
Low traffic Use Bayesian testing for faster, actionable results

Key Testing Areas

Page Type Test Ideas
Homepage Search bar prominence; personalized content; hero CTA; social proof placement
Landing page Headline; form length; CTA copy; above-fold layout
Product/Category Quick view; descriptions; add-to-cart placement
Checkout Form fields; progress indicator; trust badges; guest checkout
Pricing Plan order; anchoring; CTA per tier

Personalization: Personalized experiences generate ~41% more impact than generic ones.

Commercialization Infrastructure

Module Purpose
Data & BI Data warehouse; user behavior events; agile surveys
A/B testing Experiment platform; statistical significance; backend-controlled variants
User education Help docs (multi-language); update notifications; EDM
Attribution Ad pixels; attribution model; impression-to-click-to-sale tracking

Avoid: Intrusive interstitials; popups that block content. Prefer non-intrusive ad formats.

Foundational Requirements

  • Analytics: Map funnels; identify drop-off points (analytics-tracking, traffic-analysis)
  • Qualitative: Heatmaps, session recordings, user tests—understand why drop-off occurs
  • Technical: Dedicated resources for 2–4 tests/month; maintain momentum

Output Format

  • Funnel map (stages, conversion rates, drop-off)
  • Hypothesis (if X, then Y because Z)
  • Test plan (variant, metric, sample size, duration)
  • Implementation checklist
  • landing-page-generator: Landing page structure and copy
  • cta-generator: CTA design and placement
  • analytics-tracking: GA4, events, conversion tracking
  • traffic-analysis: Attribution, funnel analysis
  • copywriting: Headline, CTA copy for tests

Also use when the user mentions "CRO," "conversion rate optimization," "A/B test," "split test," "funnel optimization," "checkout optimization," "form optimization," or "conversion funnel." For pricing psychology, use pricing-strategy.

Alternatives

A/B Test SetupWhen the user wants to plan, design, or implement an A/B test or experiment, or build a growth experimentation program. Also use when the user mentions "A/B test," "split test," "experiment," "test this change," "variant copy," "multivariate test," "hypothesis," "should I test this," "which version is better," "test two versions," "statistical significance," "how long should I run this test," "growth experiments," "experiment velocity," "experiment backlog," "ICE score," "experimentation program," or "experiment playbook." Use this whenever someone is comparing two approaches and wants to measure which performs better, or when they want to build a systematic experimentation practice. For tracking implementation, see analytics. For page-level conversion optimization, see cro.Marketing · MITAb test analysisAnalyze A/B test results with statistical significance, sample size validation, confidence intervals, and ship/extend/stop recommendations.
