Is ChatGPT Traffic The New Main Channel Yet?
For about a year now, I haven’t gone a month without someone in ecommerce telling me their ChatGPT referrals are climbing. You’ve probably watched chatgpt.com creep up your own referral report too.
I do this more than I’d admit — I check that column way more often than the number deserves.
But “it’s growing” and “it’s a channel I should fund” are two different sentences. The second one needs a timeline, and until recently nobody had the data to draw one.
So let’s look at what the volume actually did, and then at whether the money followed.
The Volume Is Bigger Than You’d Guess
Adobe, running its own analytics across US retail sites, clocked GenAI-sourced traffic up 1,200% against July 2024. That’s not a typo. It’s roughly 13x in a little over a year.
Since September 2024 it’s been doubling about every two months. Over the 2024 holidays it ran 1,300% above the year before, and Cyber Monday hit 1,950%.
Growth like that looks like an early channel finding its legs. And it’s not one market’s quirk: BCG’s survey of more than 9,000 people across nine countries found shopping use of GenAI up 35% between February and November 2025, with daily users increasingly leaning on the assistant as the main stop before a purchase. Even in Japan the usage rate came in at 48%.
But The Money Doesn’t Grow In A Straight Line
Here’s where it gets interesting. Kaiser and Schulze, at Goethe University Frankfurt and Mannheim Business School, tracked 973 ecommerce sites and found something odd. ChatGPT referrals’ conversion rate (CVR — the share of visitors who actually buy) kept improving, while their average order value (AOV — the revenue per order) kept sliding.
Put those two together and you get a genuine reversal: more people are buying, but each basket is worth less, so the gains partly cancel out.
Adobe draws the same shape from another angle. GenAI traffic still converts about 9% below the traditional average — but back in July 2024 that gap was 43%. So the distance is closing fast, not sitting still. This isn’t “it doesn’t work”. It’s “it works in a more tangled way than the headline number lets on”.
So When Does It Actually Become A Main Channel?
This is the part a marketer wants pinned down. Kaiser and Schulze’s time-series read is careful: ChatGPT referrals are trending toward the traditional channels, but they’re unlikely to reach (where the two perform about the same) inside a year.
And the share is still tiny — ChatGPT referrals sit at roughly 0.21% of traffic. On that number alone, calling it a main revenue source is early. But how deliberate the purchase is changes how fast it catches up; the more considered the buy, the better these referrals tend to do. So a world where high-consideration categories close the gap first is very much on the table.
Conclusion: Lock In Measurement Before You Lock In Budget
AI referrals are growing, no argument. But treating them as a main channel today is a leap. What pays off right now is the boring part — a measurement setup that can call the moment it does tip, plus a small budget line for experiments before you bet real money.
At a minimum, split your AI referrers out of the “direct” bucket and read the same three numbers every week against a fixed definition: referral share, conversion rate, and average order value. Adobe’s tracking and the Kaiser & Schulze 973-store study give you an outside benchmark to hold your own curve against. Do that now, and you won’t be scrambling on the day it finally goes mainstream.
If you want the conversion side in more depth, ChatGPT traffic out-converts paid social, if you read two numbers instead of one picks up right where this leaves off.
