**Leak attributes:** `chromeInTotal`, `chrome_trans_clicks`, Chrome view/click aggregates in site scoring modules.
Documentation describes ingestion of **Chrome browser telemetry** (aggregated) into site/document quality evaluation. Independent analysts (SparkToro, iPullRank, Optimal) flagged this as contradicting prior Google denials about Chrome data in ranking.
- Google almost certainly uses **multiple quality inputs**; Chrome may feed popularity / engagement proxies
- Data is likely aggregated and normalized — not "Chrome history ranks your site"
- Correlation with NavBoost: real users who know your brand may generate healthier click streams
1. **Brand building** — PR, reviews, community mentions → more direct navigational traffic
2. **Performance & UX** — Slow or broken flows reduce repeat visits measurable in aggregate
3. **HTTPS / security headers** — Trust for financial YMYL; aligns with user retention
4. **Avoid fake engagement** — Purchased traffic with zero brand affinity may not help sustainable signals
