Using Robots.txt

[semer]

I want to Block or prevent pages being accessed or indexed by googlebot. Please tell me if googlebot will NOT Access any URL that begins with my domain name, followed by a question mark,followed by any string by using Robots.txt below. Sample URL http://mydomain.com/?example User-agent: Googlebot Disallow: /?

Not sure if that would work, but you can test by changing your robots.txt and running a test in GWT > Health > Blocked URLs

You might also be interested in specifying specific URL paraments (e.g. /?sort=name&order=asc > can block sort and order parameters) from within GWT (Configuration > URL Parameters)
