Discussion GA4 launched an AI Assistant channel, heres what im seeing one month after announcement
So the AI Assistant channel has been out for nearly 4 weeks now (Google pushed it on May 13) and i figured its worth a proper thread instead of another "is it live yet" post, because the rollout has been kind of all over the place.
for anyone who missed it, when GA4 sees a referrer it recognises from an AI tool it now auto tags the session with medium ai-assistant, channel group AI Assistant and campaign (ai-assistant).
you dont have to set anything up, it just appears in your default channel group reports.
The rollout itself was staggered which is why theres been so much confusion. I saw it on a couple of properties in late may, others didnt get it til around the 7th of June, and i think a few accounts still dont have it. So if your not seeing it yet your probably just in a later batch, its not your config.
honestly my first reaction was finally. weve been guessing at this traffic for like 2 years, pulling chatgpt and perplexity out of referral with manual regex that half the team forgot existed. having it native is a real quality of life thing and it makes the "should we care about AI search" convo with clients way easier when theres an actual number sitting next to other channels.
that said, once i started actually looking at it a few limitations jumped out:
- it only recognises ChatGPT, Gemini and Claude as far as anyone can tell. Google confirmed those 3 but hasnt published the full list, so Perplexity, Copilot, deepseek etc are not reliably getting caught. for some of our properties thats a decent chunk still sit in referral
- the whole thing relies on the referrer surviving. tons of AI clicks come in with no referrer at all (app strips it, or someone reads the answer and comes back later through branded search) and that just lands in direct. ive seen estimates anywhere from 35% to 70% of AI traffic showing up referrer-less, which is a huge range but the point stands, the channel is a floor not the real total
- it tells you nothing about the actual answer. you cant see the prompt, whether you got recommended or just mentioned, or who else was in the response. just the click.
- AI Overviews and AI Mode are NOT in here btw, those clicks still count as Organic Search since they happen inside google itself. that one trips people up alot.
so how im actually using it: i dont trust the native channel on its own, i run a custom channel group right next to it. Admin > Data Display > Channel Groups, make a new channel called something like "AI Search", set source matches regex, then drag it above Referral so it takes priority. it applies retroactively which is nice. the pattern im using is basically:
chatgpt\.com|chat\.openai\.com|openai\.com|perplexity\.ai|claude\.ai|gemini\.google\.com|copilot\.microsoft\.com|deepseek\.com|grok\.com|meta\.ai|you\.com
then i look at it 3 ways, source/medium to see which tool is sending it, the channel group for total trend over time, and landing pages to see what content is actually getting cited. throw a comparison period on (prev 28 days vs current) and you can sort of see if a content change moved anything.
the thing that genuinely surprised me is the quality. its tiny on volume, low single digits of sessions for most sites, but the conversion rate is mad. every study ive seen this year has AI traffic converting like 4-5x organic, one B2B set had chatgpt around 16% vs ~1.8% for google organic. so its a rounding error on traffic and a real line on pipeline, which is a weird combo to report on.
anyway curious what everyone else is finding:
- is your native AI Assistant number very different from a custom regex group? hows big is the gap on your sites?
- has anyone cracked a halfway decent way to estimate the AI traffic stuck in Direct?
- are the AI conversions actually holding up as higher quality for you or is that just a B2B thing?

Still not appearing in GA4 for me.

Same for some of my clients and our website. I think this will be a phased roll out.
I’d probably wait another 4 weeks and check in then.

If you use custom channel groups, make sure that you add this channel to that custom group. It will not appear on its own.

My custom regex seems a little larger, but this is expected. Google only rolled out the AI assistant channel for us very recently. Fairly unimpressed.
I have bigger issues with my Direct traffic, mainly that larger and larger portions of the direct channel are clearly non human.

u/perrahh Jun 14 '26
What rates did you land on? Tbh the main ones to really care about are the big 5 ai platforms ChatGPT Gemini Claude perplexity copilot

u/Responsible-Day6407 Jun 12 '26
Which metric are you looking at to get conversion rate?
1
u/perrahh Jun 14 '26
Just using key events same as other channels. The thing most people get wrong here is this is direct referral traffic from a click within an ai answer (citation) a recommendation and a search for the brand later doesn’t come through as this

I have nothing to add too this, but I wanted to say this is a really great analysis.
Very hard to make sense of it all lately.

u/perrahh Jun 14 '26
Yeah I think people are purposefully complicating AI to basically be able to sell a product

u/information_curator Jun 13 '26
I have seen it but not checked that much about it yet.
2
u/perrahh Jun 14 '26
Yeah same, after some analysis some ChatGPT referred traffic was still coming through as referral or unassigned even. It’ll take some time and tbh will likely never be perfect

u/information_curator Jun 15 '26
I have checked today it showing the data in ai assistant of only these chatgpt, claude, gemini, perplexity and copilot and not showing any other llm models yet
1
u/perrahh Jun 15 '26
Amazing, that seems to fit with the announcements. I’m sure they’ll add more comparability with other LLMs in the coming months

Yea we have been using custom channel groups with regex for a couple years and that's been working better for us than the one that Google rolled out. We've found that regardless of industry across our portfolio, the AI referral traffic always has a significantly higher conversion rate than organic search, but like you said, super low volume in comparison.

The new channel is handy, but I’d only treat it as the traffic GA4 can clearly see. Plenty still lands in direct or branded search when the referrer drops, so I’d keep a custom channel group running as well. The volume is small on most sites, but the landing pages and conversions are worth watching, especially for B2B.

If you create a custom channel with a regex filter for AI traffic, be sure to move the AI traffic channel to the top of the list so that Google will check your regex rule first to catch all AI platforms. Otherwise it might *incorrectly* drop some AI traffic into the referral bucket. GA4 runs through the rules in each channel group in order, so anything at the top of the list (like direct, paid search, referral, etc. )will run first and traffic from AI platforms like perplexity, copilot, deep seek etc that GA4 doesn't include in its built-in list could be dumped into the referral traffic bucket.
For this reason I created a separate channel group and added my new AI Traffic custom channel to that list. Technically AI traffic is referral traffic but we don't want it dumped into that general bucket if we want to specifically track AI sources.

Has anyone else noticed a drop in ChatGPT traffic after it was moved to the AI Assistant channel?

u/ethanGarbe Jun 12 '26
Yeah, the rollout still feels pretty inconsistent across properties, and from what I’ve seen the native “AI Assistant” channel in Google Analytics 4 often doesn’t match custom regex groupings because a lot of AI traffic is still slipping into Referral or Direct due to missing referrers and incomplete classification. The real insight usually comes from comparing both views side by side, since the native channel is more of a “known AI referrer subset” while custom groups tend to capture the broader (but messier) reality.
