Data and study sample
The source is the gated FlyRank internship warehouse release available in August 2026. Daily performance covers January 2025 through June 2026. The primary analysis uses a feature cutoff of 31 May 2026 and an outcome window of 1–28 June 2026. A second cutoff on 30 April supplies the May temporal check.
| Table | Use in the study | Public treatment |
|---|---|---|
| dim_clients | Access dates and tenure control | Identifiers used only for grouping |
| dim_content | Type, intent, length, and competition controls | No URLs or hashes published |
| fact_content_daily_performance | Position, impressions, clicks, and CTR | Aggregated to one row per content item |
| fact_content_query_90d | Query entropy and momentum descriptors | No query text; overlapping measures excluded from models |
The unit of analysis is a content item within a client. Inclusion required at least 14 observed history days, seven recent days, seven outcome days, and ten outcome impressions. The resulting primary sample contains 130,833 items from 48 clients. Client history is unbalanced, so tenure enters as a control rather than a published identity. Aggregate sample record
