susan moskwa googleThe second session on my liveblogging hitllist for SES Chicago is the “Duplicate Content and Multiple Sites” moderated by Adam Audette. Unfortunatley, Michael Gray was not able to be there, so things started up with Susan Moskwa, Webmaster Trends Analyst from Google, and Shari Thurow was added on the fly.

What is duplicate content? Identical or substantially similar content. Also multiple URLs with the same content. Google realizes that duplication can be deliberate or accidental.

Basically, duplicate content in the context of a search engine is publishing different URLs that present the same content. (My Example:)

www.domainname.com
domainname.com
www.domainname.com/index.php
www.domainname.com/index.php?sid=123

Why does Google care about duplicate content? Users don’t like to see 10 nearly identical results. Also, there’s no benefit in crawling multiple urls with the same content. It’s a waste of resources for Googlebot to do that.
