What is eScore?
eScore is ScoutIQ’s 180-day demand estimate for a book.
It helps you quickly understand how often a book appears to sell on Amazon over time.
In general:
Higher eScore = stronger demand
Lower eScore = slower demand
eScore was created to give booksellers a broader view of demand, especially seasonal demand that a single Sales Rank snapshot can miss.
Why not just use Sales Rank?
Sales Rank is useful, but it is only a snapshot. It shows where a book ranks right now.
eScore looks at sales-rank history across the past 180 days to provide a broader picture of demand. That wider view can help surface patterns that Sales Rank alone may not show clearly, especially when demand is uneven or seasonal.
How eScore works
eScore is derived from sales-rank history and historical data from the past 180 days.
ScoutIQ analyzes patterns in that history to estimate how often a book appears to sell. Because Amazon does not provide a simple exact public count of copies sold, eScore should be understood as a demand estimate, not an exact sales counter.
For those who want the technical version
Under the hood, ScoutIQ may calculate eScore using different internal data paths depending on the data available.
These paths analyze rank behavior over time to estimate demand. In some cases, the system uses Keepa-based rank-history signals as a fallback during live search. In other cases, the historical-data backend uses a separate sales-detection method based on rank history.
Because of this, eScore should not be interpreted as:
an exact count of copies sold
an exact count of calendar days with sales
a direct reading of Amazon unit-sales data
Instead, eScore is best understood as a 180-day demand estimate based on rank history.
How should I use eScore?
Use eScore as a quick demand signal alongside other data like:
Sales Rank
pricing
offers
profit
No single metric tells the whole story, but eScore helps you make faster, more informed sourcing decisions by adding historical demand context to the scan.
Important note
A higher eScore usually means a book has shown stronger or more consistent demand over the past 180 days. A lower eScore usually means slower demand.
eScore is designed to help you evaluate demand more clearly than Sales Rank alone, but it is still an estimate. It works best as part of the bigger picture, not as a standalone guarantee.
Here are some examples
Current Sales Rank: 1.7MM
eScore: 6 (6 sales in the past 6 months - low demand)
Current Sales Rank: 30k
eScore: 151+ (likely selling every day - high demand)
