How to see AI referral traffic in GA4?

Short answer: Open GA4’s Traffic acquisition report, switch the primary dimension to Session source/medium, and search or filter for sources you suspect are AI assistants or AI-related web apps. Google’s AI Overviews and AI Mode clicks are counted within overall Google Search in Search Console and don’t appear as a separate “AI” referrer in GA4; expect them within your existing Google Search traffic like “google / organic” rather than a standalone AI label (https://developers.google.com/search/docs/appearance/ai-features, https://support.google.com/analytics/answer/12923437).

Open the GA4 Traffic acquisition report

The Traffic acquisition report shows where sessions come from and is designed to help you find sources for both new and returning users (https://support.google.com/analytics/answer/12923437). To open it:

• Sign in to Google Analytics.
• Go to Reports → Acquisition → Traffic acquisition (https://support.google.com/analytics/answer/12923437).

Tip: If it’s missing from your left navigation, an Editor or above can add it back (https://support.google.com/analytics/answer/12923437).

Use Session source/medium to look for AI referrals

Traffic acquisition uses session-scoped dimensions like Session source, Session medium and Session source/medium (https://support.google.com/analytics/answer/12923437). Switch the primary dimension to “Session source/medium,” then:

• Use the table search box to look up specific sources. For example, Google notes you can find organic Google Search by searching for “google / organic” (https://support.google.com/analytics/answer/12923437).
• Type short needles you expect might appear in an AI referrer name, such as “ai” to quickly surface any sources including that string. This doesn’t prove a source is an AI assistant, but it helps you triage possible candidates to review.
• If you’ve already observed candidate domains in your server logs or CRM, paste those into the table search to jump straight to them.

Compare with the User acquisition report

Traffic acquisition is session-focused and includes returning users. The User acquisition report focuses on where new users come from (https://support.google.com/analytics/answer/12923437). Use both views to understand whether suspected AI sources bring new users, returning sessions, or both.

Filter to one page or section

To see traffic sources for a specific landing page or section:

• Option 1: Add a report filter. Click “+ Add filter” → Include → Dimension: Page path and screen class → pick your path → Apply (https://support.google.com/analytics/answer/12923437).
• Option 2: Add a secondary dimension of “Page path and screen class,” then use the dimension search to isolate a page or folder (https://support.google.com/analytics/answer/12923437).

This helps you check whether AI-related sources cluster around certain guides, comparisons, or Q&A content.

Spot-check with Session source vs medium vs channel group

• Session source shows the originating publisher or inventory source (e.g., “google”) (https://support.google.com/analytics/answer/12923437).
• Session medium shows the method (e.g., “organic,” “referral”) (https://support.google.com/analytics/answer/12923437).
• Session default channel grouping rolls traffic into channels like Direct, Organic Search, Organic Social, Email, etc. (https://support.google.com/analytics/answer/12923437).

Cycle these dimensions to confirm whether a candidate is arriving as referral traffic from a distinct site/app, as Organic Search, or rolled into a broader channel.

Filter in or out sources as you learn

You can include or exclude specific sources while you investigate:

• Click “+ Add filter” → choose Include or Exclude → Dimension: Session source (or Session source/medium) → select values → Apply (https://support.google.com/analytics/answer/12923437).

Use this to isolate performance and engagement for a suspected AI source or to remove noisy trial sources from your working view.

What GA4 and Search Console can and can’t tell you about Google’s AI features

• Google states that sites appearing in AI Overviews and AI Mode are included in overall Search Console “Web” performance; there is no separate AI Overviews report there (https://developers.google.com/search/docs/appearance/ai-features).
• In Analytics, expect those Google clicks to land within your existing Google Search traffic rather than as a distinct “AI” referrer. Google’s own GA4 example shows organic Google Search presented as “google / organic” (https://support.google.com/analytics/answer/12923437), and Google notes you can use Analytics to track conversions/time spent from Search traffic in general (https://developers.google.com/search/docs/appearance/ai-features).
• You won’t see the exact prompts or AI conversation context in GA4. Use GA4 to analyze sessions, engagement, and conversions; pair it with Search Console for total Google Search clicks and impressions that include AI features (https://developers.google.com/search/docs/appearance/ai-features).

Optional pattern-matching workflow

If you need a quick triage pass across many sources:

• Use the report’s table search for simple strings like “ai”.
• Export the table and, in a spreadsheet, apply your own regular expressions to flag hostnames that match your internal watchlist (for example, domains on an .ai TLD). This is a workflow convenience, not proof that a source is an AI assistant; validate by visiting the referring site or app.

Limitations to keep in mind

• Attribution in Traffic acquisition depends on traffic-source data captured by tagging or platform integrations (https://support.google.com/analytics/answer/12923437). If a source you care about doesn’t provide distinct signals, it may be grouped under broader channels.
• Google’s AI features don’t have a separate referrer label in Search Console, and GA4 won’t reveal prompts or per-AI breakdowns (https://developers.google.com/search/docs/appearance/ai-features).

Quick checklist

• Reports → Acquisition → Traffic acquisition.
• Primary dimension: Session source/medium.
• Search the table for “google / organic” and suspected sources; validate candidates (https://support.google.com/analytics/answer/12923437).
• Add Page path and screen class as a filter or secondary dimension to focus on key pages (https://support.google.com/analytics/answer/12923437).
• Toggle Session source, Session medium, and Default channel grouping to compare rollups (https://support.google.com/analytics/answer/12923437).
• Use Include/Exclude filters to isolate or remove sources as you learn (https://support.google.com/analytics/answer/12923437).
• Use Search Console for total Google Search clicks that include AI Overviews/AI Mode (https://developers.google.com/search/docs/appearance/ai-features); use GA4 to measure engagement and conversions from that traffic.

FAQs

Can I see Google AI Overviews as a separate source in GA4?

No. Google explains that AI Overviews and AI Mode are counted within overall Search in Search Console, and you can use Analytics to analyze behavior from that traffic, but there isn’t a separate “AI Overviews” traffic source in GA4 (https://developers.google.com/search/docs/appearance/ai-features).

Do I need to add UTM tracking to see AI referrals?

Not to use the Traffic acquisition report. GA4 already records traffic-source data from tagging and platform integrations, and you can search or filter by Session source/medium (https://support.google.com/analytics/answer/12923437). UTMs help when you control the linking context (e.g., your own campaigns), but you can’t add UTMs to links you don’t control.
