While our Mass delete application takes a CSV of WooCommerce Product ID's and removes them it is inmportant you consider the consequences.


When you delete a product, it’ll generate a 404 error since search engines are unable to find this product at this particular URL. 


It wouldn’t be the best experience if users were to search for this product in the search results, click on it, and it leads to a 404.

With many SEO plugins, you have a redirect manager feature that instantly detects when you delete a post, page, or product, and if you want to create a corresponding 301 redirect (to another related product or page), or a 410 redirect (which signifies that this product has been deleted and doesn’t have any replacement).

Note that the product can still be listed on Facebook etc and you have to manually remove these. Very few integrations manage removal because of course they are earning money regardless.


Where this is really important is if you have product links on blogs or other external sites you can not control.
