A lot of SEO time right now goes into getting cited by ChatGPT. One 100-site dataset suggests that effort is buying very little traffic.
TL;DR: Marie Haynes studied 12 months of GA4 data from 100 sites and found ChatGPT sent just 0.62% as many sessions as Google organic. Her argument is that the bigger shift is Google turning search into an "agent manager," and a few early experiments are worth starting now.
📊 ChatGPT Traffic Is Much Smaller Than the Hype
Haynes analyzed 12 months of GA4 data from 100 websites, covering more than 145 million sessions. ChatGPT sent 0.62% as many sessions as Google organic. Add every other AI chatbot and the number only reaches 0.73%.
Growth has also stalled. She says ChatGPT's climb ended in August 2025, around the GPT-5 release, and it has sent fewer visitors since.
One caution. This is one dataset of 100 sites, and the article calls the sample random without listing exact dates. Treat it as a strong data point, not a law.
ChatGPT numbers can also be off for reasons that have nothing to do with demand, as a recent tagging bug showed.
💰 Fewer Visitors Convert Better, but Not Enough to Matter
Of the 100 sites, 55 tracked conversions in GA4. ChatGPT visitors converted at 13.8%, compared with 3.02% for Google organic. That is more than 4.5 times higher.
Even so, Google organic drove 96.5% of all conversions in the study, about 27 times what all AI chatbots combined produced. A high rate on a tiny base says the visitors are well qualified. It doesn't make ChatGPT a growth channel yet.
The other 45 sites weren't tracking conversions at all. If you can't see conversions, you can't tell which channel deserves your time.
🔎 The AI Search That Matters Is Already Inside Google
Haynes' point is that the AI search sending traffic today is Google's. That includes AI Overviews, AI Mode, and a core ranking system now driven largely by AI. Millions of people use it daily without leaving Google.
Her advice is to stop treating ChatGPT citations as the main goal. Track the conversions that matter to your business, and keep improving how satisfied people are with your pages, since Google's AI ranking systems try to predict what users find helpful.
🤖 Google Wants Search to Act, Not Just Answer
Search will become an agent manager.
In plain terms, search moves from a list of links to a system that coordinates tasks and can finish purchases for the user. Demis Hassabis said the web will "change quite a lot" if you think about an agent-first web, and that things will be "pretty different in a few years."
Even Google's leaders are cautious about the long term. Sergey Brin said he doesn't think anyone really knows what the world looks like in 10 years.
Haynes points to four early pieces worth knowing:
Universal Cart: A Google Wallet feature that pulls products from several retailers into one checkout. It tracks price changes, promotions, and restocks, so shoppers can buy without visiting each site.
Universal Commerce Protocol (UCP): An open standard governed by Google, Shopify, and Stripe. It lets AI agents discover, compare, and buy inventory while the merchant stays the Merchant of Record.
WebMCP: A way for websites to expose forms, calculators, and booking tools to AI agents. Haynes says it is early for most businesses, but not too early to experiment.
Intelligent Eyewear: Gemini-powered glasses running Android XR. Google's first devices are due this fall, starting with audio frames from Warby Parker and Gentle Monster, then micro-LED display glasses.
Haynes thinks the glasses may not replace search but expand it into new situations. Think of a recipe site guiding someone while they cook.
🛠️ What to Do This Quarter
Track Conversions Before Anything Else
Set up key events in GA4 so you can see which channels produce leads or sales. In Haynes' data, 45 of 100 sites had none.
Audit Your Merchant Center Feed
If you sell products, get familiar with Google Merchant Center. Haynes notes it now has a helpful AI assistant. Check your product data, stock status, and promotional markup, since those feed Google's shopping systems.
Brainstorm One Tool an Agent Could Use
List what your site already offers that an agent could use for a customer, such as a calculator, a booking flow, or a troubleshooting tool. Haynes shares a prompt that asks an AI to act as an "AI Search and Agentic Commerce Strategist" and suggest Universal Cart opportunities, WebMCP tool ideas, eyewear scenarios, and two low-lift experiments for the next quarter. It's in her article if you want to run it on your own business.
Hit reply
Does your GA4 account track conversions today, and what share of your sessions come from ChatGPT? Send me your number and I'll tell you how close it is to 0.62%.
One thing I'm thinking about: the 0.62% figure doesn't say AI visibility is worthless. It says the loudest part of the conversation and the biggest source of results are two different things.
I'd rather see a small experiment with a shopping feed or a booking tool than another month of screenshots of ChatGPT citations. Haynes says the agent pieces are early, so treat them as homework, not a deadline.
Till next time,
