This question already has an answer here:

My domain discountbox.in was performing well on the Google search engine. A couple of days back we launched the blog and forum on the subdomain discuss.discountbox.in and within the next 2 days we were kind of penalized heavily. What could be the cause of this? Do subdomains have an impact on the primary domain?

    What makes you think you were "penalized heavily"? – zigojacko Mar 31 '14 at 9:10
  • We used to get 1500 visit everyday which went down to 100 visits a day. There is no change in the structure or data on the site. Only change is we launched our blog at subdomain 3-4 days back. – Abhishek Kumar Mar 31 '14 at 13:37
