Ho problemi con google, e a quanto pare solamente con lui

Peccato che sia il più usato...

Cercando di fare il meglio per il mio sito ho controllato il mio file robots (non si sà mai)
e trovo questo schifo:
# Sample robots.txt file (make sure the filename is ALL LOWERCASE on Linux/Unix systems)
# This file should go in your web site's ROOT directory
# The root directory is where your site's main /index.html file would be found
# It is usually found in /yourhomedir/public_html/ or /yourhomedir/httpdocs
# Where "yourhomedir" is your user account's name
#
# We invite you to also check out our popular contribution: Simple Template System (STS)
# It lets you layout or change your OSC look-and-feel by modifying a single HTML file
# http://www.oscommerce.com/community/contributions,1524 or SimpleTemplateSystem.com
# Enjoy! - Brian Gallagher @ DiamondSea.com
# This says to apply these settings to ALL search engine spiders/crawlers
User-agent: *
# These settings will keep spiders from indexing your unwanted pages
# This assumes that your OSC install is in your web site's ROOT directory
# ie: http://www.yoursite.com/index.php <- Use if this brings up your OSC main page
Disallow: /admin
Disallow: /account.php
Disallow: /advanced_search.php
Disallow: /checkout_shipping.php
Disallow: /create_account.php
Disallow: /login.php
Disallow: /login.php
Disallow: /password_forgotten.php

Disallow: /shopping_cart.php
# These settings will keep spiders from indexing your unwanted pages
# This assumes that your OSC install is in your web site's ROOT directory

# Feel free to add any other pages on your site that you don't want to be indexed by
# the search engines.
# PLEASE NOTE: Any pages that you list here should be secured by other means if you
# don't want people to be able to view them, as some malicious users will look at a
# robots.txt file to try to find "hidden" or "secret" areas of web sites to find
# confidential information.
# Just Uncomment a line or add new ones as you see fit.
# Disallow: /private
# Disallow: /hidden
# IF YOU DO NOT WISH TO HAVE THE GOOGLE IMAGE BOT SCAN YOUR DOMAIN FOR IMAGES
# THEN YOU CAN INCLUDE THE FOLLOWING IN YOUR ROBOTS FILE.
# I FOUND THAT MY BANDWIDTH USAGE DROPPED BY A MASSIVE AMOUNT AFTER I GOT RID
# OF THE GOOGLE IMAGE BOT. ALL I HAD WAS IMAGE HUNTERS STEALING PRODUCT SHOTS
# AND NOT EVEN BROWSING THE SITE.
User-agent: Googlebot-Image
Disallow: /
Vorrei sapere oltre ad eliminare testo e doppioni.. qual'è il file robots migliore per osc???
Altra domanda... questo robots è fatto per google, lo seguono alla lettera anche gli altri motori di ricerca???
GRAZIE!!
