Understanding how Adspert handles historical data helps you better interpret your campaign results and optimization progress.
Data Access Limits
Adspert can only access historical data that each advertising platform makes available through its API.
This time range differs depending on the platform:
Platform | Historical data availability | Notes |
Amazon Ads | Up to 60 days | Applies to detailed reports such as keywords and product targets. Aggregated data may extend further, but Adspert primarily uses detailed performance data. |
Google Ads | Up to 90 days | Full granularity guaranteed for the last 90 days; older data may be incomplete. |
Microsoft Ads (Bing) | Up to 90 days | Similar data policy as Google Ads. |
eBay Ads / Walmart Connect | Around 30–60 days | Depending on platform-specific reporting interfaces. |
Data Used for Optimization
Even if more data is technically available, Adspert focuses on the most recent 30–90 days for its optimization models.
Older data is less relevant due to:
Changing competition and seasonality
Price adjustments and listing updates
Shifts in user behavior and demand patterns
By concentrating on recent data, Adspert ensures that your campaigns adapt to the current market situation rather than past trends.
Special Cases
New campaigns or newly connected accounts: Adspert automatically uses all available historical data to speed up the learning phase.
Older performance comparisons: For long-term or year-over-year analysis, you can retrieve historical reports directly from your advertising platform. Adspert does not use these older data points for active bid optimization.
Summary
Technically accessible: up to 90 days (depending on platform)
Used for optimization: typically 30–90 days
Older data is not considered because it no longer reflects current performance dynamics.
