Robots.txt Syntax for Dynamic URLs

[btreloar]

I want to Disallow certain dynamic pages in robots.txt and am unsure of the proper syntax. The pages I want to disallow all include the string ?Page=

Which is the proper syntax?
Disallow: ?Page=
Disallow: ?Page=*
Disallow: ?Page=
Or something else?

Hi, James. It's not pagination I'm trying to disallow. The site structure has URLs that include things like "Page=give&...", that opens up a blank form ... but it comes from scores of web pages we want to spider. Since the "give" page is an empty form, we're getting tons of duplicate content errors as a result.

Hi Bill,

Disallow: /?Page= will work

Thanks

Thanks, Alick300 — unfortunately, the slash doesn't appear like that in the URLs on this site: they look like this
www.domain.com/page.html?Page= .........

In running through an online robots.txt tester, all three versions in my original question seem to work. Until proven otherwise, I'm using the first one because it's the simplest.
