The correct GA4 Data API names for fields models most often get wrong. Use these before calling `get_ga4_data` — wrong names return a hard error.
The correct shape for `dimension_filter` in `get_ga4_data`. Wrong structure returns an "Invalid dimension_filter" error. Use these templates.
Measure traffic arriving from AI tools — ChatGPT, Claude, Perplexity, Gemini, Copilot, and others — and understand how it behaves compared to other channels.

| Analysis type | Why not available | Where to do it instead |
|---|---|---|
| Funnel analysis (drop-off by step) | runFunnelReport exists in the API but is not exposed by this MCP | GA4 UI → Explore → Funnel Exploration |
| Cohort retention (week N return rate) | runCohortReport not exposed | GA4 UI → Explore → Cohort Exploration |
| User path / flow analysis | Not available in aggregate API | GA4 UI → Explore → Path Exploration |
| Per-user event sequences | API returns aggregate rows only — no individual user journeys | BigQuery export (raw events) |
| Real-time custom breakdowns | Realtime API is limited to last 30 minutes, basic dimensions | GA4 UI → Realtime report |
| Raw event-level data | Data API aggregates; no row-level access | BigQuery export |
| Segment overlap / Venn analysis | Not a native API feature | BigQuery or GA4 Explore comparisons |
| Custom channel group definitions | Read-only via API; custom groups must be created in UI | GA4 UI → Admin → Custom Channel Groups |
date_rangesdate_range_startdate_range_enditemsViewed, itemsAddedToCart, itemsPurchased, purchaseRevenue, cartToViewRate) — aggregate only, not per-session funnelTell them: the GA4 Data API returns aggregate metrics, not event sequences. For funnel drop-off between specific steps, use GA4 Explore → Funnel Exploration. For cohort retention (week 1 / week 2 return), use GA4 Explore → Cohort Exploration. These analyses require the GA4 UI or a BigQuery export, not the Data API.
