Late Orders from Clicks in Past X Days
Customers may click on an ad today and end up buying the product several days or weeks later. However, Amazon will not attribute these orders to its respective clicks indefinitely.
When considering performance metrics for keywords or searchterms (such as the number of orders, conversion rate or ACOS) you should keep in mind the following attribution limits for Sponsored Products and HSA:
- Sponsored Products - Attribution up to 7 Days
- Headline Search Ads - Attribution up to 14 Days
How is this important for the aggregate PPC Overview?
Depending on how much time your customers take before buying a product after they click your ad, all sales related metrics will tend to look better for HSA than for SP.
In other words:
- Sales for HSA might be higher than for SP
- Conversion Rates might be higher for HSA than for SP
- ACoS might be lower for HSA than for SP
Double Check Sponsored Products Keyword Performances
Especially in the case of Sponsored Products it can therefore always be worth double checking any seemingly bad keywords before setting them to negative.
If common sense suggests a certain keyword is very much relevant for a given product, even though it is displaying a negative Performance after x clicks, you may want to consider giving that keyword some more time.
After all, it may already have led to sales, but from customers who, for example, might save a lot of products in their basket before buying them at the end of the month.
