You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.
On the other hand, I'd like to know how many people constitutes your new experience as an indipedent consultant? Infact, as others noted in the comments here, what you suggest is perfect especially for an in-house SEO situation or in for an Web Marketing Agency with at least 5/8 people working in. Even if all you say is correct and hopefully what everybodies should do, I honestly find quite difficult to dedicate all the amount of time and dedication in order to check all the steps described in your post. Or, at least, I cannot imagine myself doing it for all the clients.
In addition to optimizing these six areas of your site, analyze your competitors and see what they are doing in terms of on-page optimization, off-page optimization (competitive link analysis) and social media. While you may be doing a lot of the same things they are, it’s incredibly important to think outside the box to get a leg up over the competition.
Sending out regular newsletters and promoting offers through email is a great way to stay in touch with your customers and can also help to get traffic to your website. Provide useful information and links to pages on your website where they can learn more, such as through blog posts and landing pages for particular offers. Just make sure that you don`t continually bombard your readers with emails or your customers will either disengage with, delete, or unsubscribe from your emails.
