Final answer:
Conversions are typically calculated at the campaign level when there is a discrepancy between lookback windows for various objects in digital advertising campaigns. The campaign level provides a detailed assessment of the performance of specific advertisements, utilizing designated lookback windows to credit conversions to the correct ads.
Step-by-step explanation:
When calculating conversions with different lookback windows for advertising campaigns, the conversion level that is typically used depends on the platform and the type of conversion tracking system in place. However, in many digital advertising platforms, conversions are calculated at the campaign level or ad level, as these levels provide enough detail and aggregate data to assess the performance of specific advertisements or strategies.
Each campaign can have its own lookback window to accurately track conversions related to the specific ads run within that campaign. The lookback window is the time period after an advertisement is viewed or clicked in which a conversion, such as a sale or sign-up, is credited to that advertisement. This allows advertisers to measure the effectiveness of their campaigns over a specific timeframe, ensuring they have the data necessary to optimize their marketing efforts.
