You track it in three places, because three different things are being counted. Your analytics tool counts the visits that arrive from an assistant such as ChatGPT or Perplexity. Google Search Console counts how often your pages were shown inside AI Overviews and AI Mode. Your CRM records the contacts and deals whose source is an AI referral. Each report answers its own question, so read each one for what it measures and keep the numbers apart.
