Thanks for both the replies and advice.

All the catalogue and shopping cart functionality is in the /stock directory so I have disallowed that the robots.txt and hopefully the next time google checks it, it will obey it.

I have also added <meta name="robots" content="noindex,nofollow" /> to the main catalogue/cart page within that directory so hopefully that will take effect.

i will keep track of the logs and see what effect this has.

cheers,

Barry
