If you need to delete many products in Shopify based on some criteria, it is really hard to do it in Shopify's admin. When we discovered this problem, we built a Smart Bulk Delete Products app on the Shopify App Store. The app filters products based on your selected criteria and deletes all the products that match it. You can watch in the video how I filter products based on two criteria out-of-stock and creation date. This way, I can delete products older than 1 year, 2 years, or X years.
