Google webmaster tools now shows the sources of crawl errors. When I checked the webmaster tools I received a couple of error messages but I couldn't identify where to find out the sources of link pages that are linking to these error page. Please help?
If you go into the webmaster tools page and follow the links Dashboard > Diagnostics > Web crawl it gives a good list of the errors and linked from information. If linked from information is "unavailable" then most likely it was going direct from the sitemap or from a previous known list of pages that google has cached.
Google webmaster tool always show the result that a fortnight ago sometimes u delete the page but it will be Google database. so wait for 15 days and see the difference.
