    I have a lot of duplicate content cause by:
    • Pagination
    • Products in multiple sub-categories
    • Multiple sub-categories in categories
    • A large variety of query strings
    • Filters that reload the page with the same URL

    I was wondering if anyone has cleaned their site with the canonical tag and how well it worked.

    The <link rel="canonical"> element works... but unfortunately ONLY at Google. Though Yahoo! and Microsoft also said that they would support this new version of the link element when it was announced 2 years ago, Google is the only search engine so far that has actually implemented support for it. So using it fixes your problems with one search engine. Not good.

    Matt Cutts has said on numerous occasions this should ONLY be used as an absolute last resort to fix URL canonicalization issues and the duplicate content/split page rank issues that arise as a result. It is MUCH better if you can fix canonicalization issues with 301 redirects OR by changing your site architecture to eliminate your duplicate content.
