At Orchid Box we have gained a lot of experience in understanding the methods used by Google, especially how it caches and indexes websites.
Sometimes clients’ website have urls they don\’t want to be exposed, searchable or even visible to the general public. Previously methods have relied on Google, submitting a URL removal request to Google and hope that they will action it within a 2 month time frame.
Fortunately you can now get your page removed from Google’s search results by following the instructions below:
In order to remove your page from the Google index you need to have the following access:
FTP
Google Webmaster tools
An account with a powerful PR site (such as prlog.org)
We have seen that Google downloads robots.txt file every hour and it checks removal requests every 2/3 hours.
We have been able to de-index pages from Google SERPs within 12 hours of initiating the above 5 action points.
