KPI Metrics

"Blocking & Tackling" metrics

Inspired by Lean Analytics "One Metric That Matters" and in turn by Dave McClure's "Pirate Metrics"

Virality Engine

• Viral coefficient: invitation rate * acceptance rate
• Viral cycle time: first invite sent datetime - join datetime

Traffic sources and campaign effectiveness (the SEO stuff, measuring how well you get attention.) Signup rates (how often you get permission to contact people; and the related bounce rate, opt-out rate, and list churn.) Engagement (how long since users last used the product) and churn (how fast does someone go away). Peter Yared did a great job explaining this in a recent post on “Little Data” Infrastructure KPIs (cost of running the site; uptime; etc.) This is important because it has a big impact on conversion rates.
