Data & funnel analytics

01What is it?
Analytics tracking, interpretation, funnel analysis, product metrics, and ROI measurement. What sets it apart is how it narrows marketing analytics into one specific workflow rather than a broad, generic prompt.
02Inputs
Context for marketing analytics: your goals, audience, constraints, and any source material the skill asks for.
03Output
A ready-to-use result for marketing analytics: the analysis, copy, or recommendations the agent produces.

Data & Funnel Analytics

Workspace Context

Read bootstrap context before asking questions: strategy/brand.md for brand, audience, offer, channels, tools, constraints, and metrics; about/me.md for personal voice; content/ideas.md and content/calendar.md for content planning. Use legacy product-marketing context files only as fallback. Save generated drafts to content/<platform>/drafts/YYYY-MM-DD_short-topic-slug.md, and route durable learnings back to strategy/brand.md, about/me.md, or content/ideas.md.

Operating Contract

This skill is self-contained for its frontmatter scope: use its local instructions, references, scripts, and assets as the playbook; ask only for missing task-specific inputs; hand off to adjacent skills instead of expanding scope; and return an actionable artifact, decision, plan, draft, or diagnostic.

End-to-end analytics: set up tracking, interpret data, analyze funnels, measure product engagement, validate conversion paths, and calculate ROI.

Principle: Track for decisions, not data — every event should inform an action.


Analytics Tracking

Event Naming Convention

Format: object_action in lowercase snake_case.

signup_completed | cta_hero_clicked | checkout_started | onboarding_step_completed

Rules: Specific over vague (cta_hero_clicked not button_clicked), past tense for completed actions, context in properties not event name.

Tracking Plan

CategoryEventKey Properties
Marketingpage_viewpage_title, page_location, referrer
cta_clickedbutton_text, location, page

trial_startedplan, source
purchase_completedplan, value, currency
E-commerceproduct_viewedproduct_id, category, price
product_added_to_cartproduct_id, price, quantity
checkout_startedcart_value, items_count

Standard Properties

  • User context: user_id, user_type (free/paid/admin), plan_type
  • Attribution: source, medium, campaign, content, term (UTM params)
  • Page: page_title, page_location, content_group
  • PII hygiene: Never send email, name, or phone as event properties. Use hashed user IDs only.

GA4 Implementation

// gtag.js custom event
gtag('event', 'signup_completed', {
  'method': 'email',
  'plan': 'free',
  'user_id': userId
});

// GTM dataLayer
dataLayer.push({
  'event': 'signup_completed',
  'method': 'email',
  'plan': 'free'
});

Enhanced Measurement (enable in GA4): page_view, scroll, outbound_click, site_search, video_engagement, file_download.

Conversions: Admin → Events → Toggle "Mark as conversion." Counting: once per session (form submit) or every time (purchase).

UTM Parameters

Convention: utm_source={channel}&utm_medium={cpc|email|organic|social}&utm_campaign={id}&utm_content={variant}&utm_term={keyword}

  • Apply to ALL paid and email links
  • Never use on internal links (breaks session attribution)
  • Lowercase, hyphens not spaces
  • Document in a UTM tracking sheet

Privacy & Compliance

  • GDPR/CCPA: Implement consent management, block GA4 until consent granted
  • GA4 data retention: 14 months max (Admin → Data Settings)
  • IP anonymization enabled

Execution Workflow

Step 1: Gather the Funnel

Ask the user:

Show me your funnel. I need to see:

  1. What's the funnel URL or can you describe each step?
  2. What's the entry point? (Ad, email, content, etc.)
  3. What are you selling? (Free offer, low-ticket, high-ticket?)
  4. What's the desired action? (Opt-in, purchase, call booking?)
  5. Where is traffic coming from? (Paid ads, organic, email list?)
  6. What's your current conversion rate? (If known)

Funnel Types (Reference):

  • Lead Funnel: Free offer → Opt-in → Thank you + Upsell
  • Tripwire Funnel: Low-ticket offer ($7-47) → Order form → OTO
  • Webinar Funnel: Registration → Webinar → Application/Sale
  • Application Funnel: Free content → Application → Call → Sale
  • Challenge Funnel: Free challenge → Daily content → Pitch

Step 2: Score Hook Strength (0-10, Weight: 2x)

Evaluate the first 3 seconds of the funnel experience:

  • Does the headline stop the scroll?
  • Is there a pattern interrupt (unexpected element)?
  • Is the hook specific to the target audience?
  • Does it create curiosity or urgency?
  • Is the promise immediately clear?

Scoring Criteria:

ScoreDescription
9-10Scroll-stopping hook, specific to audience, creates immediate curiosity
7-8Strong hook, grabs attention, clear promise
5-6Decent hook, somewhat generic, could be stronger
3-4Weak hook, generic, doesn't stand out
0-2No hook, boring headline, immediate bounce

Red Flags:

  • Generic headlines ("Welcome to our page")
  • No headline above the fold
  • Hook doesn't match the traffic source
  • No curiosity or urgency element
  • Wall of text before the hook

Hook Formula:

[End Result] + [Time Period] + [Address Objection]
"How to [Result] in [Time] Without [Objection]"

Step 3: Score Story Connection (0-10, Weight: 1.5x)

Evaluate the emotional journey:

  • Is there an origin story or epiphany bridge?
  • Does the story create relatability ("I was like you")?
  • Is there conflict and transformation?
  • Does it build belief that the solution works?
  • Is the story relevant to the audience's pain?

Scoring Criteria:

ScoreDescription
9-10Powerful epiphany bridge, emotionally resonant, builds complete belief
7-8Good story, relatable, some emotional connection
5-6Story present but weak, or too long, or disconnected
3-4Minimal story, facts without emotion
0-2No story, just features and claims

Red Flags:

  • No story at all
  • Story about the company, not the customer
  • Story too long (loses attention)
  • Story doesn't connect to the offer
  • No transformation shown

Epiphany Bridge Framework:

1. Backstory (where you were)
2. Wall (the problem you hit)
3. Epiphany (the breakthrough discovery)
4. Plan (what you did about it)
5. Success (the result you achieved)
6. Transformation (who you became)

Step 4: Score Offer Clarity (0-10, Weight: 2x)

Evaluate the offer presentation:

  • Is the offer immediately clear?
  • Is the value proposition compelling?
  • Are the deliverables specific?
  • Is there a stack (multiple components)?
  • Is the price positioned correctly?

Scoring Criteria:

ScoreDescription
9-10Crystal clear offer, overwhelming value stack, irresistible positioning
7-8Clear offer, good value stack, compelling presentation
5-6Offer understood but not compelling, weak stack or positioning
3-4Confusing offer, unclear what they get
0-2No clear offer, or buried below the fold

Red Flags:

  • Offer buried below the fold
  • Confusing pricing or options
  • No value stack
  • Features without benefits
  • Multiple CTAs competing

Offer Clarity Test: Can someone explain what they get in one sentence?

Step 5: Score Value Ladder Fit (0-10, Weight: 1x)

Evaluate funnel positioning in the ascension path:

  • Does this funnel match the traffic temperature?
  • Is there a logical next step after conversion?
  • Does the offer ascend to higher-ticket?
  • Is there a tripwire to create buyers?
  • Is the pricing appropriate for this funnel stage?

Scoring Criteria:

ScoreDescription
9-10Perfect ladder fit, clear ascension, obvious next step
7-8Good ladder fit, ascension path exists
5-6Decent fit, but gaps in the ladder
3-4Funnel doesn't fit the ladder, pricing mismatch
0-2No value ladder, dead-end funnel

Red Flags:

  • High-ticket offer to cold traffic
  • No upsell or next step after purchase
  • Pricing jump too large between steps
  • Lead magnet unrelated to paid offer

Step 6: Score Traffic Match (0-10, Weight: 1.5x)

Evaluate traffic-to-funnel alignment:

  • Does the funnel match the traffic temperature?
  • Is the message-to-market match strong?
  • Does the landing page continue the conversation from the ad?
  • Is the ask appropriate for the traffic type?
  • Is there congruence from click to page?

Scoring Criteria:

ScoreDescription
9-10Perfect match, message continues seamlessly, appropriate ask
7-8Good match, minor disconnects, mostly congruent
5-6Decent match, some friction, message shift
3-4Poor match, confusing transition, wrong ask
0-2Complete mismatch, traffic bouncing immediately

Red Flags:

  • Selling high-ticket to cold traffic
  • Long-form sales page for hot traffic
  • No scent trail from ad to page
  • Headline doesn't match ad copy
  • Asking for too much too soon

Step 7: Score Conversion Path (0-10, Weight: 1x)

Evaluate the path to conversion:

  • Is the CTA clear and prominent?
  • Is there one primary action (not multiple)?
  • Is the form simple (minimal fields)?
  • Is there friction in the process?
  • Is the next step obvious after conversion?

Scoring Criteria:

ScoreDescription
9-10One clear CTA, minimal friction, obvious next step
7-8Clear CTA, some minor friction, good path
5-6CTA present but not prominent, some friction
3-4Multiple CTAs competing, confusing path
0-2No clear CTA, or buried, major friction

Red Flags:

  • Multiple CTAs on the page
  • Long forms with unnecessary fields
  • No CTA above the fold
  • Unclear what happens after clicking
  • Exit popups before they've read anything

CTA Best Practices:

  • One primary CTA per page
  • Button text = outcome ("Get Instant Access")
  • CTA above the fold AND at the end
  • Minimize form fields (name + email max for opt-in)

Step 8: Calculate Final Score

Formula:

Hook Strength × 2 = ___
Story Connection × 1.5 = ___
Offer Clarity × 2 = ___
Value Ladder Fit × 1 = ___
Traffic Match × 1.5 = ___
Conversion Path × 1 = ___
─────────────────────────
TOTAL = ___ / 100

Step 9: Generate Recommendations

For each dimension scoring below 7, provide:

  1. What's wrong (specific diagnosis)
  2. How to fix it (actionable steps)
  3. Example (show them what good looks like)

Example Validations

Example: Leaky Funnel

User's Funnel: Lead magnet opt-in page

Issues Found:

  • Generic headline: "Download Our Free Guide"
  • No story, just bullet points
  • Form asks for phone number (unnecessary friction)
  • No scent trail from Facebook ad

Validation:

Total: 46/100 - Broken Funnel

Priority Fixes:

  1. Hook: Rewrite to "How I Got 50 Clients in 30 Days Without Paid Ads"
  2. Story: Add 2-3 sentence epiphany bridge about discovery
  3. Traffic Match: Match headline to exact ad copy
  4. Conversion Path: Remove phone number, keep name + email only

Example: Strong Funnel

User's Funnel: Webinar registration

Strengths:

  • Scroll-stopping hook with specific result
  • Strong origin story video
  • Clear value stack for attending
  • Perfect traffic match from YouTube ads
  • Single CTA, minimal form

Validation:

DimensionScoreNotes

Conversion Path8/10Clean, but could add countdown

Total: 85/100 - Conversion Machine

Minor Optimizations:

  1. Add countdown timer to increase urgency
  2. Tighten video story to under 2 minutes

Common Validation Mistakes

  1. Ignoring Traffic Temperature: The funnel might be great for the wrong traffic
  2. Missing the Hook: First 3 seconds determine everything
  3. Forgetting Mobile: Most traffic is mobile—test on phone
  4. Too Many CTAs: One page, one goal
  5. No A/B Testing Reference: Ask what they've already tested
  6. Ignoring the Ad: The funnel starts with the traffic source

ROI Analyzer Reference Guide

Core Formulas

1. ROI (Return on Investment)

ROI = (Net Profit / Total Investment) × 100%

Where:
Net Profit = Revenue - Total Costs
Total Costs = Investment + Operating Costs

Example:
- Investment: 100M KRW
- Revenue: 200M KRW
- Operating Costs: 50M KRW
- Net Profit: 200M - 50M - 100M = 50M KRW
- ROI: (50M / 100M) × 100% = 50%

2. Break-Even Point (BEP)

For Project Investment:

Break-Even Point = Total Investment / (Revenue per Unit - Variable Cost per Unit)

Or for subscription:
Break-Even Months = Total Investment / Monthly Net Profit

Example:
- Investment: 120M KRW
- Monthly Revenue: 20M KRW
- Monthly Costs: 10M KRW
- Monthly Net Profit: 10M KRW
- BEP: 120M / 10M = 12 months

For Conversion-Based Projects:

Break-Even Conversion Rate = Investment / Potential Revenue

Example (Phase 0 → Phase 1):
- Investment: 50M KRW
- Phase 1 Contract: 200M KRW
- BEP: 50M / 200M = 25% conversion needed

3. Payback Period

Payback Period = Investment / Annual Net Cash Flow

Or monthly:
Payback Months = Investment / Monthly Net Profit

Example:
- Investment: 240M KRW
- Monthly Profit: 20M KRW
- Payback: 240M / 20M = 12 months

4. Net Present Value (NPV)

For multi-year projects:

NPV = Σ (Cash Flow_t / (1 + r)^t) - Investment

Where:
- t = year (1, 2, 3...)
- r = discount rate (typically 10-15%)

Example (3 years, 10% discount):
- Y0: -200M (investment)
- Y1: +50M / 1.1 = 45.5M
- Y2: +100M / 1.21 = 82.6M
- Y3: +150M / 1.33 = 112.8M
- NPV: 45.5 + 82.6 + 112.8 - 200 = 40.9M KRW ✅

Advanced Analysis

Customer Lifetime Value (LTV)

LTV = ARPU × Gross Margin % × (1 / Monthly Churn Rate)

Example (B2B SaaS):
- ARPU: 50,000 KRW/month
- Gross Margin: 80%
- Monthly Churn: 5%
- LTV: 50,000 × 0.8 × (1/0.05) = 800,000 KRW

Target: LTV:CAC ≥ 3:1

Customer Acquisition Cost (CAC)

CAC = (Marketing Spend + Sales Spend) / New Customers

Example:
- Marketing: 10M KRW/month
- Sales: 5M KRW/month
- New Customers: 50/month
- CAC: 15M / 50 = 300,000 KRW

Target: CAC Payback < 12 months
