Data freshness

Data freshness describes how recent the information actually represented by a report is. Specify the observation or complete reporting period it covers. Google discusses freshness in terms of data collection, processing and reporting, distinguishing faster partial data from later, more complete daily data.[1] A recently refreshed screen therefore need not contain recent or complete source information.

For a store report, check both the timestamp of the latest usable source observation and coverage of the period. Distinguish that age from data latency, the delay between a particular event and its availability. State the timezone and measurement time. Google's published typical processing times explicitly are not an SLA or guarantee; they establish no guarantee for another product either.[1]
