What is the proper way to deal with multiple product pages?

[youngsgarden]

If an e-commerce site selling backpacks has 200 items and they only show 30 per page, what is the proper way to deal with page 2, page 3, etc?

Do you let each page rank separately? even though they are competing on the same keywords? Do you use canonical tags on pages after the first page?

You can use pagination markup that lets Google know it's one long list.

There's a whole video, from Google, about it here - http://googlewebmastercentral.blogspot.co.uk/2012/03/video-about-pagination-with-relnext-and.html

It's worth watching.

I don't know which other search engines support this markup.
