    SEOMoz is telling me I have duplicate content. I have an E-Commerce site where when you click on a category it brings you to a page with a bunch of products. Now there are many products so I have multiple pages.

    Its saying that each page is considered to be duplicate content. I don't want this happening. The URL structure is as follows:

    Code:
    http://www.mysite.com/category
    http://www.mysite.com/category-page-1
    http://www.mysite.com/category-page-2
    http://www.mysite.com/category-page-3
    You get the point. I was starting to read up on canonical URL's but haven't learned too much. It seems this may be a way to solve my issue? Any thoughts or help is much appreciated!

    Add a canonical tag before the closing head tag in the source code of each paginated page pointing to the preferred main page:

    <link rel="canonical" href="http://www.mysite.com/category" />

    simples


    This also works for other duplicate pages Ecommerce sites throw up, such as sort pages when sorting buy price, name, brand.

    Depending on what ecommerce platform you are using you might need to just turn the feature on in the settings, such as magento, or others may need a separate plugin to download.

    However i've worked on sites in the past were there was just no easy way to get a canonical in the source code (usually shitty in house CMS's) and in the end i just blocked them in robots.txt file.

    e.g: (the below would disallow any url that has 'page-' in it)

    Disallow: /*page-


    You can also tell Google to ignore certain url parameters in Web Master Tools. For example you could tell it to ignore any urls with 'page-' in.



    Canocial tag is the best bet, but if you have trouble try the other suggestions.

    I just blocked them in the robots.txt file. Will this have signifigantly different results than if I were to put the Canonical tag on each of the pages? I would like it to be as fully optimized as possible.

    I appreciate all your help. :)

    No.

    Unless you had built links to the paginated pages.

    What you will see is though, if the paginated pages were indexed in Google, they will stay in the index, but it will drop the title, description and not cache or crawl them any more and they will likely drop into the omitted results when doing a site: search on your domain, but this isn't bad or anything.

    Actually forgot to mention, if you add products/pages that are only linked from the pages that you have blocked then google wont be able to find these pages, although if you link from else where or include them in xml sitemap they will be found.

    just to clarify, DO YOU actually have duplicate issues or does SEOmoz SAY you have dulicate issues, the reason I ask is because just about any Ecommerce site will have duplicate issues. I run one myself and haven't seen any negatives, but I'm sure seomoz would.

    Remember probably 90% of the people using those free tools are using them to analyse WP, so obviously those tools are geared towards that.
