With the new update of Google algorithm called Penguin, I think my site was being penalized due to webspam. But of course I don't create post which seems to be spam to Google. It is just I think how Google index my site.
I found out that Google index the URL of my site like:
So there are so many comment/reply URL index by Google. I have already added:
Disallow: /comment/reply/ Disallow: /?q=comment/reply/
but still Google still index this URL.
Any idea how to prevent Google from indexing comments?
