404 errors come up in website sitemap?

[mitz]

Hi guys
I thought my traffic was dropping a bit and looked at my site map and found 404 errors for every page I have.

All the usual pages were there but there were extra pages that didn't exist added into the sitemap. For example

404 error page
http://www.tips4pc.com/404error.htm?404;http://www.tips4pc.com:80/Articles/Networking%20tips/Arti...

This does not exist on my website and what is the :80 in there?

Why is it looking for something that isn't there? There are at least 2000 of these urls..What can I do?

I'm confused what you mean by finding these pages in your sitemap? Is another site out there linking to these nonexistent pages? Adding :80 to the end of a domain name indicates to connect to the web server on port 80, which is the standard port that serves websites. It's implied by default when you connect to a website and don't specify a port (as we normally don't do).

wow that is a great question.. I will see if another site is linking to those pages...
Because they really don't exist.
