@jemois : the status of "0" records pages is 404.
Today, Googlebot has further slower down crawling as well as traffic is decreased drastically. In "Crawl Errors" 8000+ errors are reporting by WMT for 11th to 13th but in 1000 sample error pages all detected records are of before 11th.
Can anyone help me out to figure-out the problem with my website and share a reliable resource from where I can check whether my website is blacklisted or not?
Tedster, I would appreciate few words from you about the problem I am facing.
