How to Track 404 (Not found) Errors in WooCommerce?
If you want to see if any internal link is leading your users to a dead end, i.e. 404, enable the Track 404 (Not found) Errors option from your plugin’s dashboard.
404 or Page Not Found Error is not good from the SEO perspective for your website. Tracking 404 pages and removing the path to them will improve your search engine visibility as well as the site’s buying/browsing experience.
