If you're trying to measure traffic influenced by AI platforms (like ChatGPT or Perplexity), the easiest starting point is to use Referrer Domain in your reports. Look for domains like chat.openai.com, chatgpt.com, or perplexity.ai. These will show up when a user clicks a link from an AI-generated result and lands on your site.
If you're looking to identify actual AI crawlers or agents (i.e., automated tools accessing the site), it's trickier. Adobe doesn’t natively log user-agent strings, but if you’re capturing IPs or using a custom dimension for user-agent (via eVar or prop), you might be able to flag known AI patterns from those fields.
Another workaround: monitor traffic patterns where engagement is low (e.g., 1 page per visit, 0 sec time spent), and cross-reference that with unusual referrers or user-agent values. You can then tag or exclude them based on a bot-like behavior segment.
We haven’t seen a huge wave of traffic from these sources yet, but it’s definitely growing — worth keeping an eye on!
