robots.txt

I would like for google to ignore urls like this: http://www.mydomain.com/new-printers?dir=asc&order=price&p=3 All urls that have the parameters dir, order and price should be ignored but I dont have experience with Robots.txt. Any idea? Here's a solutions if you want to disallow query strings: Disallow: /*?* or if you want to be more precise on your query string: Disallow: /*?dir=*&order=*&p=* You can also add to the robots.txt which url to allow Allow: /new-printer$ The $ will make sure only the /new-printer will be allowed.

Simple question. I want to add: Disallow */*details-print/ Basically, blocking rules in the form of /foo/bar/dynamic-details-print --- foo and bar in this example can also be totally dynamic. I thought this would be simple, but then on www.robotstxt.org there is this message: Note also that globbing and regular expression are not supported in either the User-agent or Disallow lines. The '*' in the User-agent field is a special value meaning "any robot". Specifically, you cannot have lines like "User-agent: bot ", "Disallow: /tmp/*" or "Disallow: *.gif". So we can't do that? Do search engines
