utm_source=chatgpt.com: What It Means and How to Track It
ChatGPT has added this tag to links in its answers, though it has been reported removed at times, and we could not verify its current status. When it shows up in your analytics, someone clicked a link to your site inside a ChatGPT response. It tells you about a click, not about how often ChatGPT names you.

What the tag means
The short answer
It marks a visit that came from a link in ChatGPT. To see whether AI bots can read your site at all, run the AI crawler checker. OpenAI lists its crawlers in its bots documentation (opens in a new tab).
The tag in a URL, in plain words
A UTM URL is a normal link with tracking tags after a question mark. The utm_source part names where the visitor came from, and here that origin is chatgpt.com. Analytics tools read it and file the visit under that source.
https://example.com/pricing?utm_source=chatgpt.comThe page is the same with or without the tag. Only the reporting changes.
Where you will see it
In GA4 as Session source
In GA4, tagged traffic should show chatgpt.com in the Session source dimension. In a traffic acquisition report, filter Session source for text containing "chatgpt". Use "contains" rather than an exact match, so variants of the name still show up.
In a copied link or browser address bar
When you copy a link from a ChatGPT answer, the tag appears after the question mark. Check the address bar after you click: if you see ?utm_source=, the tag was there.
Why it sometimes goes missing
Traffic that lands in Direct
When a visit arrives with no tag and no referrer, GA4 has nothing to attribute it to, so it falls into Direct. That is standard analytics behavior. It means some ChatGPT visits may be hiding in your Direct line.
The reported removal and fix
SERoundtable reported that OpenAI appeared to have removed the UTM parameters on links in ChatGPT results. A later fix has been reported, but we could not verify it. Check your own data: compare chatgpt.com sessions and Direct sessions by week for October and November 2026, and look for a drop and a recovery.
How to remove the tag from a link
By hand
Keep the path, drop only the tracking tags. In https://example.com/guide?utm_source=chatgpt.com, delete everything from the question mark and you get https://example.com/guide.
If the link has other parameters, such as ?id=42&utm_source=chatgpt.com, remove only the &utm_source part. Deleting ?id=42 would change the page.
With a browser extension
The Chrome Web Store lists ChatGPT UTM Remover, which removes utm_source, utm_medium, utm_campaign, utm_term, utm_content and other tracking parameters from links in ChatGPT responses and clipboard content. Its page shows version 1.0.1, updated October 18, 2026, and 708 users. Read its permissions first, using Google's guidance on Chrome Web Store reviews (opens in a new tab).
We found no source showing ChatGPT sets utm_medium or utm_campaign, so expect utm_source only. For how Google treats AI answers in search, see its AI features documentation (opens in a new tab).
What this tag does not tell you
A click is not a mention
A tagged visit needs a link in the answer. ChatGPT can name your brand with no link at all, and then analytics shows nothing. Whether this traffic is higher intent is something to measure on your own site.
What you cannot see in analytics
Analytics cannot show prompts where ChatGPT named a rival instead, where it named you without a link, or which of your pages it cites. For that you need to ask ChatGPT the questions your customers ask. A tracker does that.

We asked ChatGPT about this tag
On 2026-11-08 we asked ChatGPT (chatgpt.com, logged out, with web search, from the United States) four questions and got four answers. Across them, ChatGPT named 19 distinct brands and cited 21 distinct sites. This is a snapshot, not a study.
For our first question, on what the tag means, it named only Google Analytics 4 and cited mwyconsulting.com, lenvanderhof.com and geoly.ai. It called the tag harmless and aimed at site analytics.
For "Which tools or sites show how to track ChatGPT traffic in GA4?" it named GA4, Practical Ecommerce, Generative Visibility, Leadometry, Magnitude, RankSenseAI, FlyRank AI Visibility, GSC Wizard, PingAura and Beacon.
Google Analytics 4 appeared in three answers. Profound and Searchable appeared in two each. Searchable.com was the only site cited twice.
The overlap with Google was zero. None of the 21 cited sites ranks in Google's top 10 for this query, and none of the 7 top-10 domains (eseospace.com, seerinteractive.com, genrank.io, chatgpt.com, seroundtable.com, google.com, tropk.ai) was cited.
On "How do I check whether ChatGPT mentions my website?", it said there is no official OpenAI dashboard with a full report of how often ChatGPT mentions a site. That matches the gap above. See what ChatGPT cites for your own question.
Checking whether ChatGPT mentions your brand at all
To know if ChatGPT names you, ask it your customers' questions and record the answers. Do it by hand first: open ChatGPT, turn on web search, and run five questions without naming your brand.
We built a way to automate that: our ChatGPT visibility tracker asks ChatGPT and four other AIs your prompts, then shows which brands appear, in what position and which sources get cited. It does not measure traffic, sessions or conversions, so keep GA4 for clicks. Our guide on how to rank in ChatGPT covers what to do with the results.
Frequently asked questions
What does utm_source ChatGPT.com mean?
It means a visitor reached your site by clicking a link inside a ChatGPT response. ChatGPT has added the tag to links in its answers, and analytics tools read it and label the visit's source as chatgpt.com. It records a click only, not how often ChatGPT mentions your brand.
What is a UTM URL link?
A UTM URL is an ordinary link with tracking tags added after a question mark, such as ?utm_source=chatgpt.com. The page itself does not change. Analytics tools read the tags to report where a visit came from, so the tags matter to reporting, not to the visitor.
What is utm_source in a URL?
utm_source is the tag that names where a visit came from, such as a site, app or newsletter. In ?utm_source=chatgpt.com, the value chatgpt.com says the click came from ChatGPT. It sits after the question mark and is ignored by the page.
Why does some ChatGPT traffic show up as Direct?
When a visit arrives without the tag and without referrer data, analytics cannot attribute it and files it under Direct. SERoundtable reported that OpenAI appeared to have removed the tags. Compare your chatgpt.com and Direct sessions by week to check.
Does utm_source=chatgpt.com mean ChatGPT recommended my brand?
No. It means someone clicked a link to your site in a ChatGPT answer. ChatGPT can also name your brand with no link, which leaves no tag, and a link can appear as a plain source rather than a recommendation. Ask ChatGPT your customers' questions to see how you are named.
Can I remove utm_source=chatgpt.com from a link?
Yes. Delete the tag and keep the path. If other parameters follow, remove only the utm_source one so the link still works. A browser extension such as ChatGPT UTM Remover can strip tags automatically, but review its permissions first.
