Allow me to break down how things look and let me know if you feel this setup creates an issue with duplicate content.
The site in question is a consumers buyers guide for Apple products. The site covers all the latest gadgets and accessories produced by Apple and for Apple producing. The post(s) provide a brief description about the product and informing people where they can buy it.
The site is setup like an old-fashion blog. On the main pages, and every for page that matter, you'll find full-length posts, no excerpts. The reader is only required to "click more" to see the additional photos.
There's 6 full-length per page.
Behind the scenes I use categories but on the site itself you'll find no categories. Instead, I use tags to organize things. I link to these tags fairly often too, for example, when talking about a set of speakers for the iPod I'll tag it with "iPod Speakers" or when discussing the iPad covers I'll link to the tag page "iPad covers".
The first page for the tag is set to follow/index while the subpages are set at follow/noindex.
Since my site displays full-length posts on the index pages and tag pages is this creating a duplicate content issue?
I would be happy to hear your opinions on this.
