Graphite estimates this represents a 45% decline from previous levels. The drop stems from OpenAI’s removal of the `utm_source=chatgpt.com` tag and referrer data from links in answer text, which now appear as Direct traffic in GA4 instead. Smith calls it a bug and expects OpenAI to fix it soon, though Adobe’s Cedric Huesler confirmed OpenAI acknowledged the issue on October 14 and a partial fix began rolling out on October 15, restoring tagged clicks to near pre-change levels for some domains by midday that day.\n\nAnalysts note the change aligns with GPT-6’s rollout on October 7, which introduced a new answer format omitting tags in inline links. Peec AI’s Tomek Rudzki found direct URLs in 42% of ChatGPT responses (up from 8–10%) between October 9–13, with 54% pointing to homepages. Profound observed a drop in tagged source links from 98% to 66% over the same period, while Intelligent UI formats surged from 2% to 35% of answers. Experts urge publishers to annotate October 8–15 data and compare ChatGPT/Direct traffic side-by-side, as the fix won’t retroactively restore lost attribution.","keyPoints":["ChatGPT referrals in GA4 fell 22% to 57% of baseline after October 9, per Graphite’s tracking","OpenAI removed `utm_source` tags from inline links in answer text, causing misattribution as Direct traffic","Adobe’s Cedric Huesler reports a partial fix began October 15, restoring tagged clicks to ~95–100% of pre-change levels"],"whyItMatters":"Publishers rely on GA4’s ChatGPT attribution to measure AI-driven traffic, but the tracking loss risks misreporting declines as lost interest. The fix may restore accuracy but won’t recover lost data, and competitors like Gemini already embed UTM tags.","category":{"slug":"marketing","name":"Marketing & Small Business","url":"https://digestai.news/category/marketing"},"entities":{"companies":["OpenAI","Graphite","Adobe","LLM Pulse","Profound","Peec AI"],"models":["GPT-6"],"people":["Ethan Smith","Cedric Huesler","Tomek Rudzki","Matt G.
