Stockful syncs up to two years of traffic history when you install, so for an established store these surfaces light up as soon as the initial sync finishes. A brand-new storefront needs about a week of sessions before there is enough signal to trust. Sessions are collected per product page, so everything traffic-related works at product grain - variants of the same product share their product’s sessions, split by each variant’s share of recent sales.
Where traffic shows up
Settings
From Settings → Forecasting, the Storefront traffic section:- Storefront traffic (on by default) - the master switch. Turning it off darkens every traffic surface: stats stop being computed, the dashboard count reads zero, health-check findings stop, and the toggles below disappear.
- Traffic in reorder priority (off by default) - lets traffic rank your reorder list: adds the demand-pressure sort and the surge badge.
- Traffic in forecasts (off by default) - lets traffic trends adjust demand forecasts. This switch only appears once the forecasting side has been validated and enabled by Stockful.
What the numbers mean
- Sessions (28d) - storefront sessions that landed on the product’s page over the last 28 days, allocated to the variant by its share of the product’s recent sales (evenly when the product hasn’t sold).
- Traffic conversion - units sold per hundred product-page sessions. Small samples are smoothed toward the product type’s rate and your shop’s overall rate, so a product with thirty sessions doesn’t read as 0% or 30% conversion on the strength of one sale.
- Traffic surge - sessions at least doubled against the prior 28 days, past a minimum floor, so quiet products don’t surge on noise.
