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 degree to which content can be parsed, understood, and extracted by AI systems. Machine-readable content uses semantic HTML, structured data markup, and clear typography. Content that relies on visual layout, image-rendered text, or unstructured prose has lower machine readability.
AI inference engines vary in their tolerance for machine readability gaps. Highly capable models can extract from imperfectly structured content; less capable retrieval systems require explicit structure. Designing for the lower tolerance threshold ensures consistent extraction across the AI ecosystem.
The IEO Engine architecture maintains machine readability discipline across all content types — semantic HTML, comprehensive schema markup, declarative paragraph structure, and explicit heading hierarchy. The result is content that extracts cleanly across all major AI platforms.
