How often should I audit and clean my ecommerce catalogue?

There is no universal audit frequency, but high-change catalogues benefit from continuous validation plus a deeper monthly or quarterly review. Trigger checks whenever products are imported, marketplaces are added, taxonomy changes or major seasonal campaigns begin. Instead of treating cleanup as an occasional project, define rules for completeness, consistency and freshness and monitor them automatically. The more channels and SKUs you operate, the more important it becomes to detect problems at ingestion rather than repairing them after they reach customers.
