- One number per date range, or one row per group_by value (search term, bidded keyword, page, ad group, campaign, campaign type, intent, category).
- Dimensions
- keyword · campaign_keyword · page · adgroup_name · campaign_name · campaign_type · intent · category · country · device
- Required filters
- date_range
- Aggregation
- Sums across rows. Whole-domain only, the paid statistics dataset carries no segment dimension, so a segment argument is ignored and a note is returned.
- Metric type

Caveats, freshness and failure modes
Whole-domain only: the paid statistics dataset scopes by a whole-domain flag rather than by segment, so a segment argument is dropped and the read stays whole-domain.
The search term that triggered an ad and the bidded keyword are different fields; a cost report grouped by one is not a report grouped by the other.
Same-day spend is provisional until Ads reporting settles overnight.
- Freshness
- ~1 day behind, Ads reporting settles overnight; same-day spend is provisional.
Common failure modes
- Reading a segment-scoped cost number: there is none, any segment passed is ignored.
- Summing cost across a group_by breakdown and expecting the whole-domain total; the breakdown is capped at top_n.
