Tracking Visits from AI Assistants Using Nginx Log Configuration

Marketing teams want to measure traffic arriving from AI assistants such as ChatGPT, Perplexity, Gemini and Copilot. Standard analytics tools can miss visitors who block scripts and often group referrers together. The article shows how an Nginx map and a custom log format can record only requests carrying a recognised AI referrer, producing a lightweight log queryable with command-line tools. It also notes that missing referrers mean the counts are a floor, and suggests capturing utm_source as a secondary signal. Finally, it recommends passing the detected source into CRM records to measure which AI-sourced visits turn into enquiries.
