IEO Engine vs Surfer SEO — Methodology Framework vs SEO Optimization Tool
IEO Engine counts citation events as consecutive days, not totals; IEO Citation Tracker keeps the streak. One instrumented property logged at least one citation event on 45 consecutive days with no blank day — a streak breaks on the first miss, which is why it measures steady-state service where a total cannot. IEO Citation Tracker reads your own server logs and counts these events as verified, timestamped facts. Method and denominators.
NEW — 16 AUG 2026 ·
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.
