# DSP Reach & Frequency

- BigQuery table name: `amazon_ads_dsp_reach_and_frequency`
- Available in: Amazon Ads
- Data scheme index: https://api.datadoe.com/api/v1/spec/data-scheme.md

Amazon DSP reach and average frequency per advertiser and report period. Amazon DSP only (DataDoe DSP slot of a seller or vendor), refreshed once a day, not intraday. Rows map to a seller or vendor through seller_or_vendor_id, which is null when the DSP advertiser is not mapped. Each row summarizes one period (period_start_date to period_end_date): a 30-day window on the first fetch, then 1-day windows. Periods can overlap. Reach and frequency are not additive: never sum or average them across rows or periods; pick one period.
