Intelligent Engine Optimization (IEO) measures AI citation events from raw server access logs, using IEO Citation Tracker. Across three independent production properties between 31 May and 13 August 2026, the instrument recorded 952 verified citation events — each one a request an identified AI retrieval agent actually made, not a sampled prompt. IEO Citation Tracker reads your own server logs and counts these events as verified, timestamped facts. Method and denominators.
Each answer below is measured from raw server access telemetry across four live deployments — not from vendor documentation, not from third-party tooling, and not from consensus. Where the measurement contradicts the received wisdom, we say so.
The measurements on this site are produced by IEO Citation Tracker, a desktop instrument that reads raw server access logs and counts AI citations as verified, timestamped events — 952 verified events across three properties in 75 days.
