🛍️Impact on Online Traffic and Shopping Behavior
Traffic from generative AI sources to internet retailers increased tenfold between July and September 2024. 25% of UK consumers have used AI for online shopping, a figure expected to rise.
What’s the Advanced Way to Use Google Tag Manager (GTM) for Segmenting AI Traffic in GA4? [5 Simple Steps]
If you’re investigating the chatgpt traffic drop and want to win back visibility, use this GTM + GA4 workflow to identify and segment AI-driven visits so you can diagnose what actually changed.
Google Tag Manager (GTM) allows you to identify, segment, and send AI bot traffic data to Google Analytics 4 (GA4). This method enhances AI traffic detection by leveraging custom variables, triggers, and tags.
Step 1: Setting Up Custom Variables in GTM for Bot Detection
To track AI bot traffic, we’ll create a Custom JavaScript Variable in GTM that detects AI related referrers and user agents.
- Open Google Tag Manager (GTM) and navigate to Variables.
- Click New → Select Variable Configuration.
- Choose Custom JavaScript.
- Paste the following JavaScript code to check for AI related referrer domains and user agents:
function() {
var referrer = document.referrer.toLowerCase();
var userAgent = navigator.userAgent.toLowerCase();
- Name this variable “Detect AI Bot Traffic” and Save it.
💡 Tip: This script checks both referrer domains and user agents, ensuring a more reliable AI detection.
Step 2: Creating Triggers to Detect AI Bots in GTM
Now, we need to create a trigger that fires when AI bot traffic is detected.
- In GTM, go to Triggers and click New.
- Select Trigger Type → Page View.
- Choose “Some Page Views” and set the condition:
- Variable: Detect AI Bot Traffic
- Condition: equals
- Value: AI_Bot_Traffic
- Name the trigger “AI Bot Traffic Trigger” and Save it.
💡 Tip: This trigger fires only when AI chatbot traffic is detected, preventing unnecessary tagging of human visitors.
Step 3: Creating Tags to Send AI Bot Traffic Data to GA4
Now, let’s create a GA4 Event Tag to send AI bot traffic data to Google Analytics.
- Go to Tags and click New.
- Choose Tag Configuration → Google Analytics: GA4 Event.

As AI driven search experiences grow, tracking and analyzing AI chatbot traffic in Google Analytics 4 (GA4) is essential. AI referrals, such as from ChatGPT, Perplexity, and Claude, can impact website traffic and engagement metrics.
To analyze AI chatbot traffic separately from human visitors, create custom reports using GA4 filters, explorations, and channel groups as discussed above.
Comparing AI Bot Sessions vs. Human Sessions
To compare AI traffic with human user behavior, create a second segment for organic or direct traffic:
- Repeat Step 4 but select:
- Dimension: Session Source/Medium
- Condition: Does Not Match Regex
- Value: (Use the same regex but exclude AI sources)
- Apply both AI traffic and human traffic segments in the Exploration report to compare:
- Engagement rates (Do AI users stay on your site?)
- Conversion performance (Are AI visitors converting?)
- Key event rates (Do AI users trigger key interactions?)
💡 Insight: AI generated traffic often has lower engagement but might still contribute to brand awareness.
Setting Up GA4 Custom Audiences for AI Users
To track AI driven users over time, create a GA4 Custom Audience.
- Go to GA4 → Admin → Audiences → Click “New Audience”.

✔ Update regex filters frequently to include new AI sources.
How Can I Track Traffic Coming from ChatGPT or Other AI Chatbots in Google Analytics or GA4?
Track AI chatbot traffic in GA4 by creating a custom channel group with regex for referrers (e.g., chat.openai.com, perplexity.ai, claude.ai, gemini.google.com, copilot.microsoft.com) and analyzing it in Explorations for sessions, conversions, and engagement.
This conclusion is supported by AllAboutAI analysis of Google Analytics community discussions spanning 47 practitioner comments, confirming regex-based detection as the industry-standard approach for Q3–Q4 2025.
The Current State of AI Traffic Attribution
According to Seer Interactive’s case study analyzing 7 months of B2B client data (Oct 2024–Apr 2025), AI-driven traffic currently represents only 0.07% of total organic traffic but shows strong quality:
- ChatGPT: 15.9% conversion rate (≈9× organic’s 1.76%)
- Perplexity: 10.5% conversion rate
- Claude: 5.0% conversion rate
- Gemini: 3.0% conversion rate
⚠️ The Attribution Blindspot
AllAboutAI research highlights a persistent issue surfaced in GA4 community analysis: AI traffic is often misclassified as “Direct” or bundled into “Organic,” since GA4 lacks a native AI channel. Community reports (May 2025) show this creates reporting friction and undercounts AI-assisted discovery.
Step-by-Step: Set Up AI Traffic Tracking in GA4
Method 1: Custom Channel Group (Recommended)
- GA4 Admin → Data display → Channel groups → + Create new channel group
- Name: “AI Chatbots & LLMs” → Add rule → Condition:
Session sourcematches regex
Use this 2025 pattern:
^(chat\.openai\.com|chatgpt\.com|perplexity\.ai|claude\.ai|chat\.mistral\.ai|gemini\.google\.com|bard\.google\.com|copilot\.microsoft\.com|you\.com|www\.meta\.ai|poe\.com)$💡 Keep Regex Fresh
Update monthly as new AI referrers emerge. To stay consistent across your property, reuse the same pattern in Explorations and in GTM-based detection.
- Order matters: Move “AI Chatbots & LLMs” above “Organic Search” so AI sessions don’t get misattributed.
- Verify: Reports → Acquisition → Traffic Acquisition → switch to your Custom channel group and monitor for 30 days.
Method 2: GA4 Exploration with Regex (Deeper Analysis)
- Dimensions: Page referrer, Landing page + query string, Session source/medium, Country
- Metrics: Sessions, Users, Conversions, Engagement rate, Avg. engagement time
- Filter: Page referrer matches regex →
(chat\.openai\.com|chatgpt\.com|perplexity\.ai|claude\.ai|gemini\.google\.com|copilot\.microsoft\.com) - Compare: Duplicate and invert the filter to benchmark AI vs. non-AI traffic on engagement and conversions.
Method 3: Google Tag Manager Event (Enterprise Granularity)
Create a Custom JavaScript Variable and fire a GA4 event (ai_traffic_detected) with the platform as a parameter:
function() {
var ref = (document.referrer || '').toLowerCase();
var ai = [
'chat.openai.com','chatgpt.com','perplexity.ai',
'claude.ai','gemini.google.com','copilot.microsoft.com'
];
for (var i = 0; i < ai.length; i++) {
if (ref.indexOf(ai[i]) > -1) return ai[i];
}
return 'not_ai_traffic';
}What the Data Really Shows
- Referral tracking captures only the click-through fraction of AI visibility; many AI answers are zero-click.
- Watch for brand lift proxies: branded queries in GSC, “Direct” spikes, and improved rankings on pages frequently cited by AI.
Identify AI Citations Beyond GA4
Combine manual prompt testing (ChatGPT, Perplexity, Claude, Gemini) with AI visibility tools (e.g., Otterly.ai, LLMrefs, XFunnel) to catch the 8–12× additional brand mentions that never become GA4 sessions.
What Are the Best Practices for Managing AI Chatbot and LLM Traffic in Google Analytics 4?
With AI chatbots like ChatGPT, Perplexity, and Claude driving website visits, businesses must decide how to handle AI traffic in Google Analytics 4 (GA4). Proper tracking ensures accurate reporting, clean data, and meaningful insights.
As features like Claude’s Summaries begin surfacing content directly in response windows, understanding how this impacts user behavior and referral traffic becomes essential for measuring true content performance.
Should You Exclude or Track AI Traffic?
Tracking AI traffic helps businesses understand how AI platforms reference their content, making it valuable for content driven sites. The best practice is to track AI and LLM chatbot traffic initially, analyze its impact, and then decide whether exclusion is necessary.
| ✅ Track AI Traffic If: | 🚫 Exclude AI Traffic If: |
|---|---|
| Your business relies on brand awareness and content marketing (e.g., blogs, SaaS, and informational sites). | Your business depends on accurate conversion tracking (e.g., e commerce, paid advertising). |
| You want to understand how AI is surfacing your content and its role in user discovery. | AI visits inflate engagement metrics without contributing to revenue. |
| AI referrals lead to engagement (clicks, signvups, purchases). | AI bot traffic misrepresents user behavior, leading to bad marketing decisions. |
When to Segment AI Traffic for Insights
Segmenting AI traffic helps businesses understand how AI visitors interact with their site.
📌When to Segment:>
✔ When you want to see which pages AI chatbots are surfacing.
✔ To compare AI traffic vs. human traffic in engagement, bounce rate, and conversions.
✔ To analyze if AI traffic increases brand visibility over time.
💡 Insight: Segmenting first before filtering out AI traffic prevents loss of valuable AI driven referral insights.
When to Exclude AI Traffic for Accurate Reporting
AI visits should be excluded from marketing, conversion tracking, and ad reports to prevent inflated performance metrics.
📌When to Exclude:
🚫 If AI generated sessions skew bounce rates or engagement time.
🚫 When AI chatbot visits inflate conversion numbers without real purchases.
🚫 If AI traffic interferes with ad performance tracking (e.g., PPC campaigns).
Use GA4 filters or Google Tag Manager (GTM) to block AI sources before they impact key reports. Regularly update regex filters to exclude emerging AI referral sources.
Avoiding GA4 Data Contamination from AI Bots
AI traffic can pollute analytics, making it hard to separate human user behavior from bot visits.
Best practices to prevent data contamination:
1️⃣ Use Custom Audiences → Identify AI visitors and exclude them from engagement based analysis.
2️⃣ Apply Bot Filtering in GA4 → Exclude AI visits from Google Tag Manager before sending events to GA4.
3️⃣ Monitor Anomalies → Look for sudden spikes in traffic from AI heavy referrers (e.g., ChatGPT)
Future Proofing AI Tracking as AI Evolves
AI referrals are rising, making continuous tracking crucial. As highlighted in SEO trends in 2025, refine GA4 tracking to prevent inflated metrics by setting up a dedicated AI traffic channel group.
Use Looker Studio to visualize AI traffic trends and stay updated on evolving AI search platforms like Perplexity vs. Google to understand their impact on visibility and measurement.
What’s the Best Way to Identify if My Content Is Being Cited or Referenced by AI Models Like Perplexity or Claude?

This conclusion is supported by AllAboutAI analysis showing that specialized AI visibility tools capture 8–12× more brand mentions than GA4 referral tracking alone, based on comparative analysis of 26 tool recommendations in SaaS community discussions.
The Zero-Click Challenge in AI Search
Unlike traditional search engines where ranking position directly correlates with click-through rates, AI search operates on a fundamentally different model. According to arXiv’s comprehensive GEO study analyzing query behavior across ChatGPT, Perplexity, Gemini, and Claude:
- Decision support dominates: Most prompts frame around “what to buy, when to buy, how to compare”.
- Shortlist synthesis: AI engines present 3–5 synthesized recommendations, not 10 blue links.
- Citation without traffic: Your content influences the recommendation without generating a measurable visit.
“I use Claude + Perplexity to do my research, but I always click on the references they give me. Granted, most people are likelier to be lazy…” — u/Anonymous, Aug 2025 (via r/SaaS)
This behavioral pattern means visibility ≠ traffic in the AI search era.
Manual Detection Methods
1. Systematic Prompt Testing (Free, Time-Intensive)
| Platform | Test Frequency | Query Types | What to Monitor |
