Hi jesicawillss,
The methods to follow for SEO for an e-commerce website will not differ too much from normal SEO practice. You may need to consider creating unique pages for each product you have, and optimizing each title, meta description, etc for that product specifically. So, although this is one SEO practice for a product range on an e-commerce site, it could be done for any website's content. It would then be useful for you to create backlinks straight to these internal pages, again optimizing each product specifically.
