GA4 now recognizes AI Assistant traffic for supported referrers. Use that signal carefully, then connect it to Trakkr prompts, citations, and reports.

[01]

Workflow setup

Prerequisites

GA4 installed on the site with access to admin and reporting configuration.

A known list of AI referrers and landing pages to validate against recognized AI Assistant traffic.

Trakkr tracking for prompts, citations, traffic, and reporting.

Setup steps

  1. 1

    Check the AI Assistant channel

    GA4 introduced AI Assistant traffic measurement in 2026 with an ai-assistant medium and default AI Assistant channel group for recognized referrers.

  2. 2

    Create or review a custom channel group

    Use GA4 custom channel groups to place AI assistant matching above generic Referrals, so AI traffic is not buried in the wrong bucket.

  3. 3

    Validate landing pages

    Review landing pages, sessions, engagement, conversions, and revenue where configured. Do not report traffic without checking where it landed.

  4. 4

    Compare traffic to visibility

    Use Trakkr to compare GA4 AI traffic movement with prompt rankings, citations, competitor share, and cited pages.

  5. 5

    Build a recurring report

    Send visibility, citation, and traffic summaries into Trakkr reports or Looker Studio so stakeholders see one version of the story.
