SKU Diffing

SKU diffing is the process of comparing a competitor's current product catalog against a previously captured snapshot to identify what has been added, removed, or changed.

Like "diffing" code (comparing old and new versions line by line), SKU diffing compares two catalog snapshots — yesterday's crawl and today's — to produce a precise change log. The output tells you: new SKUs (new products or variants launched), removed SKUs (discontinued or out-of-stock), and modified SKUs (price, title, or image changes).

SKU diffing is how you detect a product launch without any press release. If a competitor quietly adds 12 new SKUs overnight, your intelligence platform surfaces that signal before any marketing announcement.

GetStoreIntel runs automated SKU diffing on every crawl cycle and surfaces changes in your dashboard activity feed and via Slack/email alerts.
