Agent Experience Index

Can AI agents actually use your site?

AI agents, behavioral analytics tools, and LLM crawlers all depend on the same underlying site signals. Sites that lack proper markup are partially or entirely invisible to them, even when they look polished to a human visitor.

Where to start

What this score means for your behavioral data

Behavioral intelligence tools rely on the same signals this index measures. A lower score means your analytics tools are working with incomplete data, AI agents are navigating your site blind, and your team is making decisions on context that's fragmented or missing entirely.

Fullstory's Fullcapture automatically captures every user interaction — but the richness of what it can surface depends on how well your site is structured. Better markup means cleaner segments, more precise triggers, and AI that can act on your site with confidence.
