How to fix this Google search engine result?

[prestaaa]

I get these search engine results from google when I search my site.

booksonwaraustralia.com/en/cart?qty=1&id_product=19.

which if clicked opens up the cart with the product/book being created

How can this be fixed??

I'm new at this and I did not have the robots.txt file in place at the time of submiting - is this something robots.txt will stop. If so how long before they the entries clear from google?

You can add to the links to cart the attr.

rel="no-follow"

I believe that once google has the URL, the only way to get it to stop crawling that URL is with a 301 redirect.

I've seen sites with a robot.txt file in place, yet search engines keep crawling it, even if not indexing it.

 

Have a look at http://www.prestashop.com/forums/index.php?/topic/39736-module-duplicate-url-redirect-redirect-all-duplicate-and-non-seo-friendly-urls-to-the-default-friendly-url/ it will do a 301 redirect for cart.php, but only for Search Engines, which should get it off of the google listing the quickest.
