SEO checklist for ecommerce websites

I've been working on a guide last month or so merging what I know and what the clients I work with found useful in SEO. It got out of hand being 30 pdf pages long so far. And I'm still not finished.
Still, I wanted to share something to 'test the waters' hence this 16 point checklist.

Have a look at it and let me know what you think

btw it's no.7 for it's intended keyword so I might be onto something :-)
