It sat near 0.35% until April 2026. In May, ChatGPT visits doubled in one month. By October the share was 1.52%. Monthly ChatGPT visits rose from 8,895 to 37,245.

Organic still grew 4.7%. It added 353,493 visits in a quarter, more than ChatGPT sent in total (104,162). AI is adding to search, not taking from it.

Where the fake 96x came from

Before cleaning, GA4 showed ChatGPT traffic growing from 24,813 to 2,372,964 sessions a quarter: 96x. Bot sessions and paid ChatGPT ad clicks caused most of it. Take them out and real growth is about 4x.

The method

Track your real AI traffic in GA4, in 6 steps

The steps we used for this study. Any brand can repeat them.

  1. 01Clean

    Find AI sessions

    In GA4, report sessions by Session source / medium and filter for sources containing "chatgpt" or "openai". Add perplexity, gemini or copilot for a wider view.

  2. 02Clean

    Remove paid clicks

    Exclude sources such as "Chatgptads", or "ChatGPT" with medium cpc or paid, and any session with a paid campaign name.

  3. 03Clean

    Check for bots

    Break AI sessions down by country, device and month. A sudden jump from one country on desktop, with very short visits and no conversions, is almost always bots.

  4. 04Measure

    Compare with organic

    Divide clean AI sessions by Organic Search sessions for the same period. Track this share every month.

  5. 05Measure

    Check conversions properly

    Use purchases for ecommerce. For lead generation, use only key events that are real leads, never page views or session starts.

  6. 06Measure

    Compare on the same site

    Conversion rates differ a lot between sites, so compare ChatGPT with organic within each site before you combine results.

No time to run these yourself? We'll do all 6 on your GA4, free.

What this means for brands

5 things to do about AI search now

AI-assisted search is real, growing and valuable. It is also still built on top of organic search.

  1. Keep organic search strong

    It still brings about 99 of every 100 search visits we can measure, and AI assistants often draw on pages that already rank well. Read how generative AI is reshaping SEO.

  2. Write pages AI can quote

    Put a short, direct answer near the top. Use clear headings, specific facts, prices, locations and FAQs. Our guide to AI content optimisation shows how.

  3. Add clean structured data

    Schema tells search engines and AI tools who you are, what you offer and where you are.

  4. Make AI visitors easy to convert

    On lead-gen sites they arrive ready to act. Put calls, forms and WhatsApp buttons where they land.

  5. Measure AI traffic every month

    Track it as a clean percentage of organic. Remove bots and paid clicks first, then watch the share and its conversion rate. Also track your brand's visibility in ChatGPT.

How we ran the study37 websites · 12 months · GA4 · bots and paid clicks removed See the method

We compared the first 3 months (Nov 2025 to Jan 2026) with the last 3 months (Aug to Oct 2026). Three-month windows smooth out one-off spikes.

We removed paid ChatGPT ad clicks, bot sessions, duplicate GA4 properties and sites without data at the start. For conversions we used purchases on ecommerce sites, and only real leads (form fills, calls and WhatsApp clicks) on lead-gen sites.

What this data can't tell you

  • GA4 misses some AI visits. When an AI app passes no referrer, the visit shows up as Direct, so the true AI share is likely higher.
  • Only ChatGPT. Perplexity, Gemini and Copilot are not included. Google AI Overviews are counted inside organic search.
  • Small numbers per site. Many sites get a few hundred ChatGPT visits a year, so per-site conversion rates can swing.
  • Leads differ by site. We compare ChatGPT with organic within each site, but a lead on one site is not the same as a lead on another.
  • Last-click view. Someone who first found a brand in ChatGPT and came back through Google counts as organic.
  • Sample. 37 websites from one agency's clients, mostly in India and Asia, plus some global ecommerce. Every brand is anonymised.

FAQ

ChatGPT and AI traffic, your questions

Can't find your answer? Email us at hello@unbundl.com.

How much traffic does ChatGPT send compared with Google?

In our data, about 1 visit for every 76 from organic search, measured from August to October 2026. ChatGPT's share of organic traffic was 1.52% in October 2026, up from 0.35% a year earlier.

How do you track ChatGPT traffic in GA4?

Start in the Traffic acquisition report and filter the session source for chatgpt.com. Then take out paid ChatGPT clicks and check for bots, because both inflate the number. All 6 steps are on this page.

How do I know if my AI traffic is bots?

Look at where the visits come from and how they behave. Bot sessions often come from a country you don't sell in, view one page and leave, and arrive as an overnight jump. On one site in our study, 2.9 million sessions in 3 months were bots.

Why does my GA4 show far more ChatGPT traffic than this?

Most likely bots or paid clicks. Before cleaning, GA4 showed ChatGPT traffic on our sites growing 96x. After removing 2.9 million bot sessions and paid ChatGPT ad clicks, the real growth was about 4x.

Does ChatGPT traffic convert better than organic search?

On lead-gen sites, yes. From August to October 2026, ChatGPT visits converted at 8.2% against 5.6% for organic. On ecommerce sites it was mixed, at 0.44% against 0.60% overall.

Does AI traffic show up as Direct in GA4?

Some of it does. When an AI app passes no referrer, GA4 counts the visit as Direct traffic. So the true AI share is likely a little higher than the paper shows.

Is AI search taking traffic away from Google?

Not on this data. Organic search grew 4.7% over the same period and still brings about 99 of every 100 search visits we can measure. AI is a fast-growing layer on top of search. Here is how to get your business on ChatGPT.

Does the study include Perplexity, Gemini or Google AI Overviews?

No. The study counts ChatGPT only. Google AI Overviews are counted inside organic search, because GA4 does not separate them. See Google AI Mode vs AI Overviews.

Where does the data come from?

Google Analytics 4 data from 37 websites we manage SEO for, from November 2025 to October 2026, pulled on November 9, 2026. Every brand in the study is anonymised.

Is this US data?

Mostly not. The sample is mostly websites in India and Asia, plus some global ecommerce. Results may differ in your market, which is why this page shows you how to check your own numbers.

What is the free AI traffic check?

We run the same cleaning steps from the paper on your Google Analytics. We remove bots and paid clicks, then show you your real AI share of organic and how those visitors convert. It's free. For ongoing work, see our ChatGPT SEO services.
