Since one of my sites "fell" last week I decided to play around good and hard within webmaster tools. Found some odd stuff that I feel I should clean up.
Under crawl errors, I have over 3000 pages "not found". This is mainly due to some of my old pages that were html based are linked to my old cgi based cart. I have not used that cart in years so all the links are dead. Even though I have all these old pages forwarded to my new cart with 301 Redirects (via .htaccess), it is still reporting the errors. Is it safe to just remove the old pages from my server that haven't been in use for several years? Or what should be my plan of attack?
