Analytics

Core metrics

• Impressions: count of render events.
• Clicks: clicks on actionable elements (anchors/buttons), not dismiss actions.
• CTR: clicks / impressions.
• Unique Users: distinct user/session keys on impression events.

Attribution and data source

Attribution modes:
- attributed: all variants have context-attributed impressions
- mixed: some variants attributed, others message_rollup fallback
- message_rollup: no attributed impressions available

Variant rows prefer experiment-context attribution first; if unavailable, they fall back to message-level rollup.

coverage = attributedImpressions / totalImpressions

where:
- attributedImpressions: impressions with context.experimentId match
- totalImpressions: all impressions for experiment variant messages

Trend and range behavior

• Experiment detail defaults to a 14-day reporting window.
• API supports up to 90 days for experiment analytics requests.
• Impression trend series is derived from context-attributed experiment events.
• Variant table can still show message_rollup fallback when attribution is incomplete.

Confidence guidance in dashboard

• < 100 impressions: low confidence.
• 100-499 impressions: directional read only.
• 500+ impressions: sufficient for directional winner calls.
