Why are advertising metrics delayed compared to sales data?

Advertising metrics often appear later than sales data because advertising platforms use attribution models that require time to process and validate conversion events.

MerchantSpring retrieves advertising performance data from Amazon Advertising APIs, which only provide finalized metrics after Amazon completes its attribution calculations.

Why Advertising Data Takes Longer

Several factors contribute to advertising data delays.

• Attribution Windows
  Amazon advertising uses attribution windows to determine which ad interactions contributed to a sale.
  
  For example, a purchase may be attributed to an ad click that occurred several days earlier.
  
  Amazon waits until the attribution window closes before finalizing some metrics.

• Data Validation
  Amazon validates advertising performance data before publishing it through APIs.
  
  This helps prevent duplicate conversions or inaccurate reporting.

• API Update Cycles
  Advertising data APIs update less frequently than sales APIs.
  
  This means campaign performance metrics may appear later in reporting tools.

Typical Advertising Data Delays

Common update delays include:

• Spend: several hours
• Clicks and impressions: several hours
• Attributed sales: up to 24 hours

These delays are normal across most advertising platforms.

Notes: 

• Advertising data will typically catch up once attribution windows close.
• Campaign metrics may change as additional conversions are attributed.
• Comparing advertising performance day-by-day may show temporary differences.

Reviewing advertising performance over weekly or monthly periods generally provides the most accurate view.
