### Key metrics & PostHog

#### Developer Adoption
**Importance:** Measures the rate at which developers start using a tool, from initial signup to making their first API call. It's the most critical top-of-funnel metric for developer tools, as it indicates the health of the onboarding process and the tool's initial appeal. High adoption is a leading indicator of future growth and product-market fit.

**PostHog approach:** Track key developer touchpoints like `account_created`, `sdk_installed`, and `api_call_made` with properties for tech stack and company size. Create adoption funnels to analyze the journey from first contact to active use, identifying drop-off points. Use cohort analysis to track developer retention over time and map the developer journey to understand common paths to success. Alerts can signal developer churn risk. Non-technical users, like DevRel teams, can build these funnels and dashboards without code to monitor adoption trends and measure the impact of their initiatives.

#### API Usage
**Importance:** Tracks the frequency, volume, and patterns of API calls made by developers. This metric is vital for understanding which features are most valuable, how developers are integrating the product, and the overall health and performance of the API. It directly reflects product engagement and stickiness for a developer-focused product.

**PostHog approach:** Instrument all API endpoints to track events like `api_request` and `api_error`, with properties for the specific endpoint, response time, and error type. Create API performance dashboards to monitor usage, latency, and error rates in real-time. Set up alerts for performance degradation or spikes in errors. Use correlation analysis to understand which usage patterns are associated with retention or expansion. Non-technical users can use dashboards to see which endpoints are most popular and identify which customers are experiencing the most errors.

#### Documentation Engagement
**Importance:** For developer tools, documentation is the product. This metric measures how developers interact with documentation, including page views, search queries, and time spent on pages. High engagement indicates that the documentation is useful and helps developers solve problems, which is critical for adoption and reducing support load.

**PostHog approach:** Track documentation interactions like `docs_page_viewed`, `code_sample_copied`, and `tutorial_completed`, with properties for the page, search terms, and user segment. Use session recordings to see where developers get stuck or confused. Analyze search patterns to identify content gaps and create dashboards to monitor documentation effectiveness. Non-technical users, like technical writers, can use these insights to prioritize content updates and improve the developer experience without needing to write code.

#### Community Growth
**Importance:** Measures the health and vibrancy of the developer community around a product (e.g., on GitHub, Slack, Discord). A growing, active community provides social proof, drives word-of-mouth adoption, offers scalable support, and is a rich source of product feedback. It acts as a moat and a powerful growth engine.

**PostHog approach:** Track community interactions from various platforms by sending events like `forum_post_created`, `github_issue_opened`, or `community_event_attended`. Use properties to segment by contribution level and topic. Create dashboards to monitor community engagement and growth trends. Use cohort analysis to track member retention and identify "power users" who can become community champions. Non-technical users, like community managers, can easily track these metrics to demonstrate the value of their programs.

#### Support Ticket Volume
**Importance:** The number of support tickets created by developers. While some tickets are expected, a high volume, especially on recurring themes, points to friction in the product, confusing documentation, or a poor onboarding experience. Analyzing this data is key to improving the product and reducing operational costs.

**PostHog approach:** Integrate your support system (e.g., Zendesk, Jira) with PostHog to track `support_ticket_created` and `support_ticket_resolved` events. Enrich these events with properties like ticket type, priority, and resolution time. Use correlation analysis to link support tickets to specific in-product behaviors or documentation pages, identifying the root cause of developer friction. Dashboards can help monitor support trends and efficiency. This allows non-technical team members to identify which product areas are generating the most support load.
