GA4 "AI Assistant" channel group (added 13 May 2026)

Google Analytics 4 added a new **default channel group called "AI Assistant"** on 13 May 2026 ([GA4 channel groups doc](https://support.google.com/analytics/answer/9164320?hl=en)). When a referrer matches a recognized AI Assistant (ChatGPT, Gemini, Claude, etc.), GA4 automatically:

• Categorizes the session under the **AI Assistant channel group**
• Sets the **Medium dimension to `ai-assistant`**

This is the **attribution-side counterpart** to the new GSC AI Performance Report (rolled out 3 June 2026 — see `/digital-marketing-pro:gsc-ai-performance`). Because the GSC AI report intentionally excludes click data, the GA4 AI Assistant channel is currently the cleanest path to attribute *actual traffic* coming from generative AI surfaces.

**Recommended GA4 setup checks** when onboarding a brand:

1. **Confirm the channel group is live in the property.** Newer GA4 properties get it automatically; older ones may need it to appear after Google's backfill completes. If the brand reports their channel reports look unchanged after 13 May, check explore reports filtered by `sessionDefaultChannelGroup = "AI Assistant"`. 2. **Add the AI Assistant channel to custom reports + dashboards** — for any brand running an AEO program (`/digital-marketing-pro:aeo-geo`, `/digital-marketing-pro:aeo-audit`), the AI Assistant channel trend is now a primary KPI alongside organic search clicks. 3. **Don't merge AI Assistant into "Organic Search" or "Direct".** Some legacy reporting templates roll AI traffic into Direct (because referrers weren't always present) or Organic Search (because answer engines feel "search-like"). Both are misattributions now — the AI Assistant channel is the authoritative bucket. 4. **Reconcile with `aeo-audit` outputs and the GSC AI report.** Three data sources, three different views:

• `aeo-audit` (synthetic probing) — what AI engines *could* say about the brand
• GSC AI Performance Report — actual impressions in Google AI Overviews / AI Mode (no clicks)
• GA4 AI Assistant channel — actual *traffic* from non-Google AI assistants (clicks materialized)

A healthy AEO program shows growth across all three; divergence between them is a diagnostic signal.

The blind spot: Google's own AI surfaces are filed as Organic Search (checked 2026-10-04)

Google's default-channel definitions ([support.google.com/analytics/answer/9756891](https://support.google.com/analytics/answer/9756891)) say three things:

• **AI Assistant** rule: "The medium exactly matches 'ai-assistant'". GA4 sets that medium (and the campaign `(ai-assistant)`) when the referrer matches its list of AI assistants. Google's channel description names ChatGPT, Gemini, Deepseek, Copilot and Grok; the 13 May 2026 release note also names Claude.
• The AI Assistant channel "excludes Google's AI Overviews and AI Mode".
• **Organic Search** is the channel for non-ad links in organic-search results, "including Google's AI Overviews and AI Mode".

So a click from an AI Overview or from AI Mode is counted as Organic Search. The channel page documents no dimension that separates it from a classic blue-link click. Consequences:

• **Never report the AI Assistant channel as "all AI traffic."** It is non-Google assistant traffic only.
• **Never subtract or estimate an "AI Overviews share" of Organic Search** from GA4 data. No first-party metric for it exists, and an estimate presented as data is a fabrication.
• When AI Overviews impressions rise in Search Console while organic clicks fall, report both numbers side by side. Say plainly that GA4 cannot attribute the clicks to AI Overviews or AI Mode.
