What is duplicate content and how can I avoid being penalized for it on my site?
I'm working with a CMS that allows me to post content in to multiple categories.
So, I have this link:
www.site.com/category/green-cars Here are the GREEN cars TITLE: A Big green car INTRO: this is a great big green car.
But then I have this link:
www.site.com/category/big-cars Here are the BIG cars TITLE: A Big green car INTRO: this is a great big green car.
So essentially - for every item of content, header and the intro sentence is the same regardless of the category the item appears in.
Will a search engine penalise the site for having the same content in this way?
I've looked at canonical links, but I don't think this is relevant here. All my content points to the same page - but the content may appear in multiple categories first.
Or am I worrying about nothing?
