(**I'm really sorry for the awful formatting of this comment. I'm having a really hard time getting the formatting to cooperate at all. I swear it's not user error but then again I could be wrong). Great question, Becky. I hope more people respond with good examples (Duluth Trading did not impress me, sorry Jordan). We're always searching for examples of ecommerce sites that do great on-page optimization on their category and product pages. It seems easy to find ecommerce sites with great design and intuitive filtering but rarely any that do any "next-level SEO" - which therein probably lies the answer that you don't "SEO" a page or page template, it happens by good design and functionality. We realize that, but it's still an on-going hunt to find any ecommerce sites that do anything unique or clever with the optimization of their content.
On-page aspects we look for are as follows:
Internal Linking:
- how many
- what anchor text
External Linking:
- do-follow or no-follow
- how many
- what anchor text
- target="_blank"
Description Copy:
- how many words, format
- how many subheadings
- formatting of subheadings
- do they link in subheadings
Images:
- how many
- what size
- alt text
- file name
- title and/or caption
Headings:
- how many h1s, h2s, h3s
- how many characters
- how many keywords
- how many variations of keywords
Structured Data:
- what do they markup with schema
- any schema that we're not already doing
Social Buttons:
- what social do they offer sharing to
- any unique or clever social share enablement
- do they offer text link to phone (a favorite of mine)
- email to friend
I'm sure there's even more to consider but that was my top-of-mind list. If I find or think of any good examples I'll come back and comment. I'm sorry that I don't have any great examples but I did want to chime-in to say that I think your question is a great one. Thanks.
edit: Someone linked to ModCloth in the comments on the Moz FB page that posted your question in the feed. From a simply design perspective, which is not my forte, ModCloth impressed me. Also, The Tie Bar. I'm also really impressed with The Wirecutter and their sister-site, The Sweethome.
