Best way to find all url parameters?

[nicole.healthline]

In reference to http://googlewebmastercentral.blogspot.com/2011/07/improved-handling-of-urls-with.html, what is the best way to find all of the parameters that need to be addressed?

Thanks!

I don't know that there is one best answer for this. For a given site, I'd try a couple of things.

1. If I'm using a CMS for shopping cart, look at the documentation and see if it references parameters used. A shopping cart often uses parameters, as does anything that involves sorting results in different orders.

2. I'd do a site:domain.com search on the site and look at the URLs that are indexed and see if any are indexed with parameters, and determine if those need to be indexed or should be excluded.
