AI assistants and LLM-powered tools are increasingly driving visits to websites. GA4 often misattributes those visits (e.g., direct / (none)), so you need to set up explicit rules to capture and report them. This post shows an easy, repeatable setup: create a custom channel group, use regex filters in Explorations, validate traffic, and build audiences for remarketing or deeper analysis.
Why this matters (short)
AI tools are becoming a genuine traffic source. If GA4 doesn’t label them, you lose visibility into content that gets surfaced by AI — and you miss optimization and remarketing opportunities. Grouping AI referrals gives you a dedicated view of sessions, engagement, and conversions coming specifically from AI tools.
What you’ll need
- GA4 property with Editor access (to create channel groups and audiences)
- A simple list of AI referrers (examples below)
- Optionally: permission to add UTM tags where you control the links (e.g., in plugin integrations or shared links)
The right SEO tools don’t just save you time—they empower you to make smarter decisions, uncover hidden opportunities, and accelerate your business growth. Choose wisely, optimize continuously, and let your tools become the foundation of your online success.
Quick list of AI referrers to watch for
Common examples to include in rules/regex:
- chat.openai.com (ChatGPT)
- perplexity.ai
- bard.google.com (Google Bard / Gemini)
- copilot.microsoft.com
- claude.ai / claude.oai.hf (Anthropic / hosted variants)
You’ll expand this as new tools appear.
Create a Custom Channel Group
Why: Default GA4 channel groups are fixed. A custom channel group lets you create a single “AI Tools” channel that aggregates referrals from AI sources. (Google Help)
How:
- Open your GA4 property.
- Click Admin (bottom-left) → under the Property column click Data Settings → Channel Groups.
- Click Create new channel group (or edit an existing custom one).
- Add a new Channel and name it AI Tools.
- Add one or more rules for that channel using Source (or Session source/medium)
Avoid overly broad matches that accidentally capture unrelated sources. Test rules in Explorations first.
Build a reliable regex list
Regex lets you capture multiple AI sources in one rule (handy for Explorations and segments). Use matches regex and escape dots.
Example regex (starter):
