Rule aeo-4d0925188b5fcb9a · measurement · high confidence
Do not measure AEO impact by referral clicks or last-click attribution, because users rarely click AI citations and most AI traffic lands as Direct in GA4.
Applies to: all
Why this matters
Pew found only ~1% click citations in AI Overviews, a ChatGPT leak shows 0.69% CTR, and 70.6% of AI-referred traffic appears as Direct with the referrer stripped; custom channel groupings recover only 50-70%.
Implementation
Type: system
Anti-pattern
Valuing AEO like a Super Bowl ad by QR-code scans — under-attributing via referral clicks.
