Traffic from ChatGPT: my platform's second-biggest source, converting 2.5x better than Google
AI is taking traffic away from search, but it hands it out under different rules. Data from my 21 domains: assistant referrals grew 18x in half a year, and a site invisible in Google can live mostly off ChatGPT recommendations. With GA4 numbers and takeaways for smaller businesses.
Karol Leszczyński · Toruń, Poland
In the Google Analytics of Matury Online, my exam-prep platform, the second-biggest external traffic source this year is not Bing, not Facebook, not any directory. It is chatgpt.com: 306 sessions since April, more than Bing and about half of what organic Google sends. Those 306 sessions produced 15 conversions, meaning 14 sign-ups and one purchase. Google produced 12 conversions from 594 sessions.
I’m writing this at a time when a large part of the SEO industry keeps repeating that AI is draining traffic from search engines and websites get the crumbs. The first half of that sentence matches what I see in my own analytics. The second half doesn’t, and this post is about the second half.
One platform, three sources, one surprising column
Let’s start with the numbers from a single domain, because there the whole phenomenon is visible end to end, from the visit to the payment. Matury Online is a Polish exam-prep service: an exercise database, interactive exam sheets, AI essay grading. A conversion here is a created account or a purchase.
Two things on this chart deserve a moment. First: ChatGPT sends half as many sessions as Google, yet it delivered more conversions in absolute numbers. Second: Bing converts about as well as ChatGPT. The picture is consistent, because both sources share the same kind of user, one who received a specific recommendation instead of a list of ten links to sift through. Someone whose assistant wrote “for practicing exam essays, try this platform” arrives with a different intent than someone comparing search results.
The growth has a clear shape too. In April, chatgpt.com sent 6 sessions to Matury Online, in June 76, in July 129. Not yet a scale that sustains a business, but the curve leaves no doubt about the direction.
Not a one-site fluke
I run and maintain 21 domains with Analytics attached: from large content sites to small service pages. I pulled every session whose source was an AI assistant (ChatGPT, Copilot, Gemini, Perplexity, Claude) from the GA4 API, January through August of this year.
From January to July, assistant traffic grew eighteenfold. And these numbers are understated, because Analytics only sees clicks that carry a referrer. When an assistant answers without handing over a link, or the browser strips the source, the visit lands in direct traffic or leaves no trace at all. Everything in this post is a floor, not a ceiling.
AI does not inherit your Google ranking
More interesting than the volume, though, is the distribution. I lined up each domain’s share of assistant traffic against its strength in classic search (clicks from Search Console):
| Domain | AI share of traffic | Google standing |
|---|---|---|
| inkmagnet.com | 61.5% | avg. position 47, a handful of clicks |
| icopywriter.pl | 30.9% | 5 clicks/month |
| zostancopywriterem.pl | 22.0% | 2 clicks/month |
| matury-online.pl | 16.0% | page 2–3 for its main phrases |
| maturapolski.pl | 1.6% | 2,561 clicks/month |
| silniki-elektryczne.com.pl | ~1% | 2,212 clicks/month, avg. position 8 |
The relationship runs opposite to intuition. Where my sites are strong in Google, assistants add a margin. Where they barely exist in Google, assistants can be the main source of traffic.
The extreme case is inkmagnet.com, an ebook generator whose site sits at an average Google position of 47. Nobody will ever see it in search results, because nobody reaches page five. And yet last week a user came in from chatgpt.com, filled out an entire order and reached the payment screen. The assistant recommended a site Google would never have shown her, because it judged how well the product fit the question, not the domain’s link profile.
That is the mechanism. Classic ranking rewards authority built over years: links, history, domain trust. At the moment of answering, an assistant reads the content and checks whether it answers the user’s question. Authority still helps, but it stops being an entry requirement. For a small business that will never push through ten entrenched results, a side door opens.
What to do about it on your own site
From my data, and from how assistants source their material, a few practical conditions follow. None of them requires an agency budget.
First, AI crawlers must be allowed in. GPTBot, ClaudeBot and PerplexityBot respect robots.txt, and a fair share of sites block them wholesale, sometimes unknowingly, because the rule shipped with a template. A site closed to the bots will not be recommended, no matter how good it is.
Second, the content has to answer the questions people actually ask an assistant, and those are longer and more specific than search phrases. Nobody asks ChatGPT “ebook generator”; they ask “what can I use to quickly make a decent ebook with a cover, ready for print”. A page that answers that question directly, in one plain paragraph, has a chance of being cited. A page that says “innovative solutions for your business” gives the model nothing to quote.
Third, specifics beat generalities more than ever. Numbers, prices, ranges and example results help, because the model builds its answer out of facts and reaches for sources that state them plainly.
Fourth, the content must be available as plain HTML. Text hidden behind a paywall, rendered only by scripts, or locked inside images does not exist for a large share of the bots.
I expanded this list, together with Google’s new audit that grades pages for AI agents, in a separate guide to optimizing sites for assistants.
Nothing on this list contradicts classic SEO. It is largely the same advice optimization guides have given for years, except now one more channel enforces it, a fast-growing one, and one that doesn’t make you wait two years for domain authority.
Who this is a real chance for
If you run a smaller business and keep losing in Google to sites that have been online for fifteen years, this is the first moment in a long while when how your site is built can outweigh how old it is. I build websites and applications for both channels at once: the classic search engine and the assistants that read content instead of rankings. Details and pricing are on my website development page.
And if you first want to check whether assistants are already sending traffic your way: open the acquisition report in GA4, add the “session source” dimension and look for chatgpt.com, copilot.com, gemini.google.com and perplexity.ai. That one column changed how I think about visibility. A few rows you don’t know about may already be waiting.
