Why Yesterday’s Amazon Ads Data May Not Be Final

When you request an Amazon Ads performance report, you might think it’s natural to assume that the figures returned are complete and final. However, data for the most recent one or two days can still be changing behind the scenes.

Amazon may initially return incomplete campaign, keyword and targeting metrics while its reporting systems continue processing activity. Impressions, clicks, sales and other performance figures can increase when the same report is requested again later.

This reporting delay matters because optimisation decisions are only as reliable as the data on which they are based.

Recent Amazon Ads Data Can Change

Amazon Ads reporting is not always fully settled within the first 24 to 48 hours.

A report requested shortly after a day has ended may contain significantly fewer impressions, clicks or attributed conversions than a report requested for exactly the same date several days later.

We recently observed a clear example in the Canada marketplace.

Initial campaign reports returned extremely low impression and click counts for recent dates. When we requested reports for those same dates again later, Amazon returned updated figures showing more than a thousand impressions and clicks for some campaigns.

The campaign had not suddenly generated new traffic in the past. Amazon’s reporting data had simply caught up.

Why Incomplete Data Can Cause Poor Optimisation Decisions

If an advertising platform treats the first report as final, it may incorrectly conclude that:

  • A campaign has received almost no traffic.
  • A keyword is failing to generate impressions.
  • A target has an unusually high cost per click.
  • Conversion rates have suddenly fallen.
  • A bid should be increased or reduced.
  • A keyword should be promoted, paused or negated.

For example, a keyword that appears to have received only a handful of impressions may look as though it needs a higher bid. Once Amazon updates the report, that same keyword may turn out to have received substantial traffic and require a completely different action.

Similarly, sales attribution can take time to develop. Acting on incomplete performance figures can make an otherwise sensible optimisation rule produce the wrong result.

How AdPartner Suite Keeps Reporting Data Current

AdPartner Suite does not assume that a recently downloaded report is permanently correct.

For dates in the near term, our system requests the reports again each day. The newly returned figures are then used to refresh the performance data already stored for those dates.

For data over a longer term, reports are still re-requested, less frequently, in case that data has changed also.

This rolling refresh process allows delayed impressions, clicks, costs, purchases and sales to be incorporated as Amazon makes them available. Older reporting periods eventually become stable and no longer require the same frequent refreshing.

Better Data Produces Better Decisions

Keeping recent reporting data current is particularly important for automated optimisation.

AdPartner Suite analyses performance at campaign, ad group, keyword and target level. Its optimisation algorithms may evaluate metrics such as:

  • Impressions and clicks
  • Advertising cost
  • Click-through rate
  • Cost per click
  • Orders and sales
  • Conversion rate
  • ACOS and ROAS
  • Performance over configurable reporting windows

These calculations need to be based on the most accurate information available.

By automatically refreshing recent report dates, AdPartner Suite reduces the risk of optimisation algorithms reacting to temporary gaps in Amazon’s data. Bid adjustments, keyword harvesting decisions and other automated actions are therefore based on a more truthful view of performance.

Intelligent Data Management Behind the Scenes

Users should not need to remember which reports may still be incomplete or repeatedly download the same reporting periods by hand. AdPartner Suite handles this process automatically.

The system recognises that Amazon’s latest figures can remain fluid, refreshes the relevant dates and ensures that performance analysis uses the latest available version of the data.

It is one of the less visible parts of advertising optimisation, but also one of the most important. Reliable optimisation begins with reliable reporting, and that means knowing when yesterday’s data may not yet tell the whole story.
