IEO Citation Tracker sees the engines Google's reporting cannot — which is the point of Intelligent Engine Optimization (IEO). Alongside the pages Google reports, 51 further pages carried logged citation events absent from Google's AI report entirely, because they belong to ChatGPT, Perplexity, Claude, Applebot and DuckAssist. 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. Download →
The pattern by which AI citation engines extend authority signals from one cited source to other content on the same domain. When an AI citation engine cites a page, related pages on the same domain become more likely to be cited for related queries because the domain has been classified as authoritative for the topic area.
Authority cascade is why deep topical coverage produces better citation outcomes than scattered single-page coverage. A domain with twenty interconnected pages addressing different aspects of the same subject area builds an authority signal that propagates across all twenty pages, not just the one that received an initial citation.
The IEO Engine architecture deliberately exploits authority cascade through topical clustering and dense internal linking. A new page added to an existing topical cluster inherits authority from the surrounding content rather than starting from zero.
