Quick answer: Around May 7, 2026, ChatGPT reportedly started embedding clickable links to brand homepages directly inside its answers far more often. According to analytics firm Profound, this “Branded Link Update” sent ChatGPT referral traffic up roughly 60–65% and shifted a big share of that traffic to brand homepages. The takeaway for GEO: AI referrals are becoming measurable and material — and your homepage now has to convert cold AI-sourced visitors.
If you’ve wondered whether AI assistants actually send traffic, a recent change to ChatGPT makes the answer harder to ignore. Analytics platform Profound reported that on or around May 7, 2026, ChatGPT began linking brand homepages inside its responses at a much higher rate. Here’s what the data shows and what it means for Generative Engine Optimization.
What changed: the “Branded Link Update”
Before the update, brand names mostly showed up as bold text with citation chips — recognizable, but not directly clickable to the brand. After it, Profound observed brand names appearing as inline hyperlinks straight to the brand’s homepage. That small UI change had an outsized effect on traffic.
The numbers
According to Profound’s reporting, the shift was sharp and sustained:
- Homepage share of ChatGPT referrals jumped from about 4% to 24%.
- Responses containing an embedded brand URL rose from ~4.5% to roughly 20–24% — about a 5x increase.
- Overall OpenAI referrals climbed an estimated 60–65% and stayed elevated.
- In Profound’s own traffic, the homepage’s share of ChatGPT referrals went from ~28% to ~62%, while deep-page share fell from ~96% to ~76% of referrals.
Winners and losers by industry
The lift wasn’t evenly distributed. B2B software and SaaS saw the biggest jump, while e-commerce barely moved — a reminder that AI referral behavior varies a lot by how people ask about your category.
Why this matters for GEO
For a long time, “AI mentions” felt like a vanity metric — your brand got named, but no click followed. If ChatGPT is now routing real visitors to homepages, share-of-voice in AI answers starts to look like a genuine acquisition channel. That raises two priorities: (1) make sure you can measure AI referral traffic, and (2) make sure your homepage can convert visitors who arrive with zero prior context about your brand.
How to act on it
- Track ChatGPT as a referral source. Set up attribution for traffic from
chatgpt.comandopenai.comin your analytics. - Optimize your homepage for cold traffic. Clear value proposition, fast load, obvious next step — assume the visitor knows nothing about you.
- Earn the brand mention in the first place. GEO fundamentals — clarity, authority, citable content — are what get your name into the answer that now carries a link.
- Watch the mention-to-visit ratio over time as these AI features keep changing.
A credibility note
Worth flagging: Profound sells analytics for exactly this problem, so it has an incentive to highlight the measurement gap. The directional story — more homepage links, more referral traffic — is consistent with what others have observed, but treat the specific figures as one vendor’s reported numbers rather than independently verified fact.
Frequently asked questions
Is ChatGPT really sending meaningful traffic now?
According to Profound’s data, yes — referrals reportedly rose 60–65% after the branded-link change, with a large shift toward homepages. Measure it yourself before reallocating budget.
Should I optimize my homepage or deep pages?
Both, but the update raises the stakes for your homepage, since more AI-sourced visitors now land there with no prior context.
How do I get mentioned by ChatGPT at all?
That’s core GEO: clear, authoritative, citable content. The branded link only helps if your brand earns the mention first.
The bottom line
The Branded Link Update is a signal that AI search is maturing from “interesting” to “measurable.” If your brand can earn AI mentions and your homepage can convert the clicks they now carry, ChatGPT becomes a real acquisition channel — not just a place your name occasionally appears.
