I'm looking for some nice script which I can install on my server and check postions of my sites in google(in few different Languages). Can You recommend some one ?
Surely you can construct your own script for something that straightforward, using PHP or the like. That way, you can control exactly what you look for and how you find it out. But, as others have said, beware! The SEs are not happy about automated scripts accessing their pages. If you make or use a script, be very sure it does not make calls more often than one every several seconds--where "several" simulates the delay a curious human who is hopping about might generate.
You can have your script working with proxies for a few bucks on scriptlance, so with proxies you cover your IP
