Elevator Talk: Is AI Traffic Really Hiding in Direct?
If AI answers rarely send a click, where does all that AI influence actually show up in your analytics? The go-to answer lately has been "it's probably hiding in direct." But is that a real explanation, or just a convenient one?
Brad Porter dropped a post from Rand Fishkin into Slack that sums up a lot of the team's attribution worries. Rand was reacting to a Semrush study of AI search in manufacturing, which found that AI referral traffic is a sliver of the total. Brad's question: if AI traffic contributes so little, is it fair to assume direct is the catch-all for everything AI influences? He's seeing direct traffic climb for nearly every client, so maybe there's something to it.
The data was limited to manufacturing and industrial brands, but the team agreed the pattern looks familiar across industries. Here's how they think about it.

AI Visibility Isn't the Same as AI Traffic
Attribution Was Always More Art Than Science
Does Perfect Attribution Really Matter?
The Takeaway
The team agreed on the short answer: "it's hiding in direct" isn't good enough on its own. Direct is a catch-all, so a rising line there can't be credited to AI by default. But AI search is plausibly part of why direct keeps climbing for so many clients. And as Pax pointed out, low AI referral traffic doesn't prove low AI influence. Someone can read about your brand in ChatGPT, never click, and show up a week later by typing your URL.
So stop looking for one AI number and watch the full set of paths a buyer takes after off-site research. That means direct traffic, branded impressions and clicks in Search Console, homepage visits, and branded paid performance. Layer in AI referral traffic and its conversion rate, plus share of voice against competitors on a prompt set you've agreed on with the client. None of these proves AI influence by itself. When they trend up together, the story gets hard to ignore.
And as Blake and Alondra put it, the scoreboard hasn't changed. Conversions and revenue were always the truth. Attribution will stay fuzzy. Do the work, show up where your audience is looking, and judge success by whether visibility, traffic, and leads move in the right direction together.
If your AI search reporting feels like guesswork, let's talk about building a measurement framework that connects visibility to revenue.
