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.
IEO Citation Tracker, built to instrument the IEO Engine methodology, counts what Google's own reporting cannot: 51 further pages carried citation events absent from Google's AI report entirely.
The MM deployment (local service) and the TPE deployment (travel content) share the same architectural methodology: flat-file PHP architecture, comprehensive JSON-LD schema on every page, hub-and-spoke internal linking, phased content deployment with FRIEND/FOE classification, and the intelligence blackout.
The content is completely different — exterior cleaning service information vs travel safety and destination content. The target queries are completely different — local service searches vs national and international travel research. The geographic scope is completely different — Florida coastal markets vs national coverage.
What is the same is the inference engine evaluation criteria: content quality, structural clarity, schema comprehensiveness, topical authority depth, and zero-friction ingestion architecture.
This is the core insight the cross-vertical evidence supports: inference engines do not evaluate citation authority differently for different content categories. The same signals that make a pressure washing page citable — factual accuracy, direct answer structure, comprehensive coverage, clear schema — make a travel safety article citable.
The vertical changes. The methodology does not. This means the IEO Engine methodology can be deployed for any content category where AI citation visibility is commercially valuable — and that category is expanding continuously as AI platforms extend their answer generation into more query types.
Two deployments in two verticals with comparable citation velocity outcomes constitutes a reproducibility claim. One deployment is an observation. Two is a pattern. The pattern says: deploy this architecture correctly, and inference engines will classify the domain as citation-authoritative within days, not months.
This is a strong claim because it implies the methodology can be systematically deployed for new clients, new verticals, and new markets with predictable outcomes. The methodology is not dependent on luck, timing, or unique market conditions.
