Event Tracking

// Track user actions
analytics.track('Button Clicked', {
  button_name: 'signup',
  page: 'homepage',
  user_id: '123'
})

// Track page views
analytics.page('Homepage', {
  referrer: document.referrer,
  path: window.location.pathname
})

// Identify users
analytics.identify('user-123', {
  email: '[email protected]',
  plan: 'pro',
  created_at: '2024-01-15'

Cohort Analysis

Week 1 Cohort (Jan 1-7):
  - D1: 80% active

Insight: Onboarding changes improved retention!

Retention Curves

Good Retention:
  - D1: 60-80%

  - Flattening curve (good!)

Bad Retention:

  • Cost per click (CPC)
  • Conversion rate (visitor → signup)

Activation

  • Signup → first core action
  • Time to value
  • Onboarding completion rate

Retention

  • DAU / MAU (stickiness)
  • Retention rate D1, D7, D30
  • Churn rate

Revenue

  • MRR / ARR
  • ARPU (Average Revenue Per User)
  • LTV (Lifetime Value)
  • LTV:CAC ratio

XLSX
by w95
×7

Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in my downloads\") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved.
