什麼是 PostHog Advanced Analytics

PostHog is a comprehensive product analytics platform that tracks user events, analyzes behavior, and runs experiments. It provides funnels (user conversion paths), cohorts (user segments), session replay (playback of user sessions), feature flags (conditional feature rollout), and A/B testing capabilities. Unlike page-based analytics (Google Analytics), PostHog tracks event-level detail, giving deep insights into feature adoption and user engagement. PostHog is unique in being self-hosted and open-source, giving companies full control over data privacy and deployment. It integrates with product teams' codebases via SDKs and provides a SQL-like query language (HogQL) for custom analysis.

❓ 常見問題

What is PostHog?
PostHog is a product analytics platform that tracks user events, builds funnels and cohorts, runs A/B tests, and replays user sessions. It's self-hosted and open-source, giving you full control over your data.
How does PostHog differ from Google Analytics?
Google Analytics is primarily for website traffic. PostHog is for product analytics: user behavior, feature adoption, retention. PostHog gives you event-level detail and session playback.
Can I self-host PostHog?
Yes. PostHog is open-source. You can self-host on your servers for full data control. Alternatively, use PostHog Cloud (SaaS).
What's feature flags in PostHog?
Feature flags control feature rollout. PostHog integrates flags with experiments, enabling you to test features on specific user segments before full launch.
How do I structure events for analysis?
Design events to represent user actions (e.g., 'Sign Up', 'Purchase', 'Feature Used'). Include properties (user_id, value, etc.) for filtering and aggregation.
