IEO Engine vs Semrush AI Tools — Methodology Framework vs SEO Tooling
IEO Citation Tracker counts what a corpus absorbs and never returns — the core measurement of Intelligent Engine Optimization (IEO). Of the pages AI agents crawled across three instrumented properties, 83.7% to 97.2% were never retrieved into an answer — read repeatedly, used never. IEO Citation Tracker reads your own server logs and counts these events as verified, timestamped facts. Method and denominators.

IEO Citation Tracker v1.21.0 is available. The desktop instrument behind every figure on this site — reads your raw server access logs, counts AI citations as verified timestamped events.
952 verified events across three properties in 75 days. Runs offline.
