Welcome to the Q&A Forum

no what you need to do is out of the conocal URL reference whatever is going to be shown to the user as the preferable content so if the pages http://www.omnipress.com/boss-woman" /> and next pages ">http://www.omnipress.com/boss-man" />  you will of course need 301 redirect as usual and anyone that tells you rel="canonical is not important does not understand much about SEO and that's not a sly on anyone. rel="canonical Tells Google where the original pages are it no matter what helps you immensely who searc it on SEOmoz see what Rand has to say   or we could just look at this link that claims it's the most important advancement in SEO since site maps so please do use a canonical-url-tag http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps here is exactly how to implement them and I wish you all the best. http://www.metatags.org/rel_canonical Sincerely, Thomas

Steve, First, I am not a .net expert and there are some here. As to the overall question though, when you 301 www.example.com/boss-man to www.example.com/big-boss-man, you do not need the canonical on the example.com/boss-man. The 301 is handling all for you. Best
