International impressions at strong positions for sites with no international audience are the most reliable AI citation proxy in GSC. A local Florida exterior cleaning business with 197 impressions from Brazil at position 4.96, 26 from Germany at 3.58, and 20 from Italy at 3.4 is being queried by AI infrastructure in those countries — not by human users.
Sort the Countries tab by impression count and look for non-English-speaking countries in the top 10. Any country with more than 10 impressions for a local or regional service site is likely AI infrastructure traffic. The position data tells you which pages the infrastructure is finding: strong positions mean the AI found your best content.
Queries that show impressions but zero clicks at positions 1-3 can indicate AI evaluation activity. When an AI platform evaluates a page for citation, it may trigger a GSC impression without a human click. A page at position 2 with consistent impressions and zero clicks may be getting evaluated by AI systems that are assessing rather than routing traffic.
Compare impression-to-click ratios across pages. Pages with strong positions and unusually low CTR for those positions may be AI-evaluation heavy. Pages with strong positions and normal CTR are producing both AI evaluation and human traffic.
GSC data is delayed 24-48 hours and is sampled — not all impressions and clicks are reported. Gate logs are real-time and complete. Comparing the two data sources provides a more complete picture than either alone.
The pattern: a Zayo sweep in gate logs at 9:43 AM on a page correlates with a GSC position improvement for that page appearing in the data 24-48 hours later. Gate logs as leading indicators for GSC data points is a documented pattern in the MM deployment — Zayo sweeps consistently preceded GSC position confirmations by hours.
