Google in this effort brought us the first video response to the #AskSearchQuality campaign, exclusively for our Indian webmasters. Answers are given by Ashish Kalsi.
This video answers the most voted questions on canonicalization and handling dynamic parameters.
Using a Canonical URL
You can use a canonical URL to specify the preferred version of URL having the same content. For this, you need to add a rel=canonical tag on every page present in the duplicate cluster of URL’s. Mark up the canonical page and any other variants with a rel=”canonical” link element.
Add a <link> element with the attribute rel=”canonical” to the <head> section of these pages:
<link rel=”canonical” href=”http://www.example.com/shoes/yellow-shoes-are-excellent” />
This indicates the preferred URL to use to access the yellow shoes post, so that the search
results will be more likely to show users that URL structure.
(Please Note: There is no guarantee that Google will always display the preferred URL.)

Using URL Parameters
URL parameters fall under 2 categories:
Active parameters – Pages whose content gets altered in some way or the other. Some examples of active parameters include sorting by brand, gender, country or order.
Passive parameters – Pages whose content remains the same. Some dynamic URL’s pointing to the same content are given below:
http://www.example.com/products/shoes/yellow?sessionid=12
http://www.example.com/products/shoes/yellow?sessionid=34
http://www.example.com/products/shoes/yellow?sessionid=567&source=facebook.com
