I have updated some url's and files in robots.txt file to block url's and files from google search results but, still files displaying in search results. As per a suggestion from a site I tried to update the robots.txt by below steps.
- In Google Webmaster tools, Health -> Fetch as Google -> type the url and click the fetch button.
but, still files displaying in search results.
Note: in Google Webmaster tools, Health -> Blocked URL's -> robots.txt file - downloaded date looks two dates back.
