ChatGPT replaces citations with direct homepage links in 42% of answers
Tomek Rudzki's one-million-prompt test finds the new links carry no referrer, hiding AI traffic as direct visits.
ChatGPT now drops a direct website link into 42% of its answers, up from 8 to 10% a week earlier. The finding comes from Tomek Rudzki, who posted it on LinkedIn on 14 October 2026.
Rudzki ran the same one million prompts twice. The first run was 2 to 7 October. The second was 9 to 13 October, after GPT-6 shipped.
Ask for the best restaurants and ChatGPT links to their homepages. Ask for the best GEO tools and it links to Peec AI. The links sit prominently in the answer.
The attribution problem
The links carry no utm_source and no referrer. Google Analytics logs the visit as direct traffic. Tools built on GA inherit the same blind spot.
Rudzki also reports that 54% of these links point at a homepage rather than the page that answered the question. The front door, not the best room.
Checking it on your own site
We think the useful move this week is a short diagnostic rather than a rebuild. Pull direct traffic to your homepage for 2 to 7 October and compare it to 9 to 13 October. A step change dated to the GPT-6 release is the signal Rudzki's data predicts.
Segment by landing page. If the lift sits almost entirely on the homepage, that fits the pattern. If it is spread across deep pages, something else is moving.
The finding is one practitioner's measurement, large sample but unreplicated. Treat the number as directional until a second source lands. The action is the same either way. Watch the direct channel, know what your homepage says to a first-time visitor who arrived with a question, and keep the pages that earned the answer worth earning it.
