We've noticed an important change to how ChatGPT is presenting links in its answers, and we wanted to share it with you.

Sources that used to sit in footnotes now appear as clickable brand links woven directly into the response text, and the change registered in tracking data immediately. Qwairy, which analyzed more than 140,000 ChatGPT answers, found the share of answers containing a brand link jumped from 0.4% to 6.2% in a single day (roughly a 14x increase). Profound saw daily ChatGPT referrals across the brand sites it monitors rise 60–65% overnight and hold there, and Similarweb measured a 157.7% week-over-week increase across its tracked websites.

Two details make this worth your attention. The first is that this traffic is now measurable. OpenAI tags its outbound links, and Google Analytics 4 added a dedicated AI assistant channel a week later, so you can see exactly how many visitors ChatGPT sends you. The second is that the traffic is unusually good. Similarweb's clickstream data shows ChatGPT referrals converting at 7.1%, ahead of organic search, social, email, and display, and second only to paid search.

We're seeing this play out in our own client data. For one of our homeowners insurance clients, daily ChatGPT-referred users roughly quadrupled after May 7 and have held at that level since. Conversion activity from the channel outpaced even that, jumping more than 500% week over week and sustaining at over five times the pre-update baseline through June and into July. Because conversions grew faster than sessions, these new visitors are converting at a higher rate than the channel delivered before, which lines up with Similarweb's finding that ChatGPT referrals rival paid search in quality. GA4's new AI assistant channel now captures all of it cleanly, so the days of piecing this traffic together from "(not set)" and referral buckets are behind us.

There is a catch, though. You can't buy your way into these answers. ChatGPT surfaces brands it can clearly identify and verify across the sources it trusts (review platforms, editorial coverage, and consistent, well-structured content on your own site).

Our SEO and analytics teams have been tracking AI visibility for clients across ChatGPT, Perplexity, and Google's AI surfaces, measuring where brands appear and how that traffic converts. If you are curious where your brand shows up in AI answers today and how to boost visibility, we'd be glad to run a baseline. Get in touch and we'll walk you through what we find.
