The cohort ROI table

Returns across many changes

The cohort ROI table zooms out from a single change to all of them. It groups your approved changes by type, like description rewrites or alt-text additions, and by month, so you can see which kinds of work paid off.

The 60-day window

The table covers a rolling 60-day window, which matches the order history Burnish reads from Shopify. Burnish deliberately does not request access to your full order history, to keep your data footprint minimal, so months older than 60 days show as empty.

How it adds up

Each cell combines the lift from every eligible change of that type in that month. Changes without enough data to measure are left out rather than estimated, and the confidence shown is the most conservative across the group.
