With the rise of conversational agents like ChatGPT, Perplexity, Gemini, or Copilot, your visibility no longer depends solely on Google. These artificial intelligences increasingly influence users' decisions by recommending websites in their answers.

But one question remains:
Is your site mentioned by these AIs?

In this article, we explain step by step how to measure visits from artificial intelligences using Google Analytics, and why it is a key lever in your SEO strategy for 2025.

Access your Google Analytics via Tag Manager

Step 1: Access Google Analytics via Tag Manager

Go to Google Analytics

Select your Google Analytics property.
Choose the website you want to analyze.

In our example, we use the site lacreme.

Step 2: Open the engagement and retention reports

Once inside the GA4 interface:

Click "Reports"
Go to the "Engagement > Pages and screens" section

Here, you see all the pages visited... but they are not yet filtered by AI.

Step 3: Filter by artificial intelligence sources

Add a filter by clicking "Add comparison".

Dimension: Session source
Condition: exactly matches
Values to enter: (non-exhaustive list)

chat.openai.com perplexity.ai copilot.microsoft.com cloud.aio.ai mammoth.ai

Step 4: Analyze your AI traffic data

Once the filter is applied, you will see:

The number of visitors coming from AI (for example, 27 visitors in a single day)
The 12-month trend (remember to expand the date range)
AI visibility peaks (up to 88 visitors per day)

But that's not all. You also have access to:

Average engagement duration
Average number of pages viewed

‍

Step 5: Compare with other traffic sources

To understand the impact of AI:

Duplicate the Analytics tab.
In the second tab, change the filter to: does not exactly match (exclude AIs).
Compare:

Source / Average engagement duration / Pages viewed per session, AI: ~2x longer, ~2 pages, Others: ~54 seconds, ~1.7 pages

💡 Users coming from AI spend more time on your site and explore more of your content. Building this kind of segmented reporting into a recurring dashboard is exactly the kind of work agencies handle; our comparison of the 10 best data analytics agencies in France profiles specialists who set up this tracking end to end.

Why this is a strategic SEO metric

You know whether your brand is being recommended in AI conversations.
You can adjust your content to maximize your chances of being cited.
You measure the real impact of your AI visibility on your acquisition.

It's an essential component of GEO (Generative Engine Optimization). Teams that want this monitored continuously without manual GA4 filtering typically bring in a specialist; our comparison of the 10 best GEO and AI visibility agencies in France lists providers who track AI citations at scale.

Conclusion

Measuring visitors coming from artificial intelligences is now an essential SEO skill.
Thanks to Google Analytics and a simple method, you can finally know whether your site is visible in AI answers.

よくある質問

How does Google Analytics detect visits coming from AI tools like ChatGPT or Perplexity ?

Google Analytics does not explicitly label traffic as “AI”. However, each AI assistant uses its own domain when opening links (example: chat.openai.com for ChatGPT). By filtering traffic based on the session source, you can isolate visits generated by AIs and measure their impact on your site.

What if I don’t see any AI traffic in Google Analytics ?

It’s normal for some websites to have little or no AI traffic yet, depending on niche, authority, and content depth. To increase your mentions: • Publish content targeting informational queries • Strengthen topical authority • Improve internal linking • Earn quality backlinks • Ensure your pages are structured and easy for AIs to parse (clear sections, schema, FAQ, definitions) AI visibility grows progressively, it’s a long-term GEO strategy.

Does more AI traffic mean my content is ranking better in ChatGPT or Perplexity?

Not necessarily. AI tools recommend pages based on: • Relevance • Freshness • Authority • Content clarity • User intent matching Traffic is only a symptom. For a real picture of your AI visibility, you need both: • Analytics data (visits) • Mention tracking (how often AIs cite your site) Together, they form the foundation of your GEO performance.
