Google webmaster tools erros
 

I am just looking into google webmaster tools and error report telling me that I have some dead link in my sitemap.xml file and on few other files on site.

I 've did manual check, and this is not true. Does anyone have idea what is going on and why google is reporting this?

I've noticed those errors and drop in listings.

thanks

Try looking at the 'Date' of error discovery. Have you fixed the link since then? If so, It's just going to take a while to clear.

You mean the search bot results are caching on their servers? :1orglaugh

Could be any number of reasons including the very simple reason that on the day they ran the report your site was down, even if just for a tiny second. Happens all the time. If you know for a fact the link is working fine now just simply resubmit your sitemap and you are good to go.

Any idea why some URLs in the sitemap do not get indexed? Is there more chance if you submit those URLs manually and directly to Google?
