No Doubt the post is great but you forgot to mention that we should also optimize our top exit pages. We should also create shipping, cancellation, Refund and privacy policy because Visitors want to know your policies. You have written a post in past about 404 pages so that should be included in this blog post like how we can take advantage of 404 pages to increase conversions. Main issue of eCommerce websites are DUPLICATE CONTENT because same product in different style or color will have same features/product description so how to fix that. Live chat also helps to get better conversions so that should be included in this post. Internal linking from post to product pages also helps so we can also use it.
These were few suggestions but i know you wanted to share 101 points and you did great.
Thanks for helping the SEO community Neil.
