Product Listings...Page 1?

Hi All;

I see a lot of e-commerce sites score Page 1 for various products.

I'm querying how best to address this as part of an SEO strategy?

I mean, would you need to create links to every single product?

Or, would an SEO campaign on set keywords serve to boost rankings for products on the site?

Thanks!

Every single product or product page should be linked.
