The tool you sent will surely send a 404 page as it doesnot exisits but

when we navigate to that page it shows the list of all products,

It's not an issue though as if there was a bad link somewhere a 404 error would be returned to the search engine - this won't be affecting your rankings at all - Google isn't going to visit pages that don't exist unless they are badly linked and I think you said that was a problem in an old sitemap you had and I assume have now removed.

Ok, Can I send you a private message please with the url and links

You can but I have seen examples as they were posted originally before the domain was edited so search engines didn't find them. If it's something else then please do send it on.

If you don't have any links on your site or in an old sitemap pointing to a badly formed URL then there really isn't a problem - search engines will only follow links, they won't speculate on links, try different variations or anything like that. In your Google Search Console any 404 pages will be listed and most of those should also include a referring URL so if there are any you should be able to get all the information there and rectify it (although search engines can be quite slow in updating their index).

Thanks for your very detailed reply

I am very well clear that google will not index a page that does not exists.

Sorry about my question again

why does the site show the list of products instead of a 404 page not foulnd error?

for eg.

http://www.website.com/nopagefound = 404 error

http;//www.website.com/products/nopagefound = shows all products in the DB "instead" of 404 page not found

I assume it's related to the way that pages are rewritten in the web.config file but it's a moot point I believe if you are not actually linking to any of them.

I get your point.

So, I will check again the file for any such redirect codes and try if there is a solution

Let me check and get back in about few hours or so

Thanks for your help and time

Best regards,

404 not found pages are the devil.
I would much rather have a list of products shown rather than a generic 404 page.

As a matter of fact, I have a custom page that shows on a 404 error for this reason.
