@shygum you could use a workflow that adds contacts where first page seen/first referring site contains markers that it came from an AI source (such as ChatGPT) and then changes the data value Original Source to AI.
@jeffvincent do you have any details on what criteria this attribution uses? For example, we had an MQL come in where “utm_source= chatgpt.com” (the MQLs occured after the AI value for Original Source was added into our system) but weren’t picked up by it (was attributed to “Other Campaigns” instead).
