Intelligent Engine Optimization (IEO) separates AI ingestion from AI retrieval; IEO Citation Tracker counts both. Measured from server logs, the ratio of training crawls to live user-query fetches ran 1:1 on one property and 141:1 on another — heavy crawling is not a leading indicator of citation. 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 frequency at which a search or AI crawler returns to re-crawl a previously visited page, measured in days between visits. Active, frequently-updated domains develop higher crawl revisit rates as crawler scheduling algorithms classify them as worth checking often.
Crawl revisit rate growth is gradual but compounding. New domains receive infrequent crawls — perhaps once every several days. As content publication activity is observed, revisit rates increase. After sustained activity, frequent-update domains receive multiple revisits per day.
The IEO Engine architecture supports high crawl revisit rates through clean infrastructure, fast response times, and consistent publication patterns. High crawl revisit rates accelerate the propagation of new content into AI inference indexes.
