En bref

Mixpanel and Amplitude are product analytics platforms that track user events, analyze behavior, and measure retention. Career path: L1 (event tracking, basic funnels) in month 1 → L2 (cohort segmentation, retention analysis, A/B testing) by month 2 → L3 (custom SQL queries, API integrations, predictive cohorts) by month 3. Product Managers and Data Analysts use these daily to identify drop-offs, measure engagement, and inform product decisions. Mastery = shipping data-driven features vs shipping based on intuition.

Qu’est-ce que Mixpanel / Amplitude (Product Analytics)

Mixpanel and Amplitude are product analytics platforms that track user events (clicks, signups, purchases, feature usage) and analyze behavior patterns to measure engagement, retention, and conversion. Both are event-based systems: your product sends events to their API (e.g., "user_clicked_button", "purchase_completed"), and the platform stores, visualizes, and analyzes them. Mixpanel emphasizes real-time event data and mobile analytics; Amplitude emphasizes retention analysis and cohort behavior. Both are standard in SaaS (B2B and B2C) for PMs and data analysts to make data-driven product decisions instead of guessing. In 2026, analytics maturity separates high-growth from stagnant companies. Teams that track behavior precisely, measure retention cohorts, and run A/B tests iterate faster. Mixpanel and Amplitude are the most popular tools for this. Alternatives exist (Heap for auto-capture, PostHog for open-source) but Mixpanel and Amplitude dominate B2B SaaS hiring conversations.

❓ FAQ

Mixpanel vs Amplitude vs Heap, which should I use?

Mixpanel: event-first, best for mobile/web tracking, no-code event capture. Amplitude: retention-focused (cohort retention table is faster), better predictive analytics, stronger user segmentation. Heap: automatic event recording (not manual), good for session-based analysis. PostHog: open-source, self-hosted option, weaker SQL. Pick based on: Are you mobile-first? (Mixpanel) Retention-obsessed? (Amplitude) Want zero implementation? (Heap)

How do I design an event taxonomy that won't become spaghetti?

Use namespacing: product.feature_name.action (e.g. checkout.cart.add_item, checkout.payment.failed). Limit 3 levels. Define required properties in a shared config (user_id, session_id, timestamp, browser). Audit unused events quarterly. In Mixpanel, use a data governance feature or script to tag stale events. Never let frontend engineers invent events freely, create a ticket process.

Why is my funnel step showing 0 conversions?

Common causes: (1) Event naming mismatch, check exact event names in event list, case-sensitive. (2) Property filters too strict, remove filters, rebuild. (3) Events out of order, funnel assumes step 1 → 2 → 3 in sequence; add a 'view' event before 'click'. (4) Time window too short, default 30 days may be too small; expand to 60 days. Test by running a custom SQL query to count events directly.

How should I analyze cohort retention to find churn signals?

Cohort retention table: create a cohort by signup date, measure % returning Day 1, 7, 14, 30. Look for flattening (e.g. 50% Day 1 → 45% Day 7 → 44% Day 14 = stalling). Compare cohorts week-over-week to spot trends (old cohorts healthier than new = onboarding regression). Drill into churned users: what features did they skip? Did they hit an error? Pair with user feedback.

What's the difference between event-based and server-side tracking?

Event-based (client-side): JavaScript tracks clicks/views in the browser, sent to Mixpanel/Amplitude. Fast to implement, noisy (ad blockers, privacy tools drop events), no auth context. Server-side: backend sends events after API calls (purchase, login, email sent). Slower to instrument, cleaner data, can tie to user auth, cost per event. Use both: server-side for critical events (payment, signup), client-side for engagement (clicks, views).

How do I handle GDPR in Amplitude/Mixpanel?

Use privacy-by-default: (1) Disable PII capture in-event (never send email/name in custom properties unless hashed). (2) Enable 'strict' or 'GDPR' mode in SDK (limits cookies, disables cross-domain tracking). (3) On user deletion, use API to bulk-delete user's events and profile. (4) Transparency: link to privacy policy in your app. Mixpanel + Amplitude both have GDPR documentation; read it before shipping.

Should I use spreadsheets or BI tools for analytics dashboards?

Spreadsheets (Sheets/Excel): quick, shareable, but stale (manual refresh). Mixpanel/Amplitude dashboards: real-time, stakeholder-friendly, limited drill-down. BI tools (Looker/Tableau): SQL queries, complex aggregations, slower to build. Rule: operational dashboards (daily checks) → Mixpanel/Amplitude. Business reviews (weekly/monthly) → spreadsheet export. Deep dives (debug specific cohort) → BI tool. Don't build 3 versions of the same metric.
