How Do You Make Your Marketing Work?

Okay... I know I'm asking a lot, I know no one here knows me, I know I haven't made a name for myself one bit, but I'm serious about pursuing and putting books out.  Right now, by the end of this month I'll have 6 additional non-fiction books and a good amount of erotica under two pennames and a novel that's in createspace right now and that I'm fixing the proof of.  Let's talk 2013 marketing.

Right now I've used KDP Select exclusively for all marketing.  I'm changing that this year.  I've been able to get 500 sales of my books in the last 5 months, but, it's time to up the ante in my opinion and really get to work.  Here's what I've come up with to do from going around these boards.  Let's add to the list.

Have a blog that's got at a minimum bi-weekly posts (John Locke Recommended not posting to the blog daily)

Write A Lot Of Works and Publish Them--Every Short Story, Every Novelette, Every Novella, Every Novel, Every Non-Fiction Work
Brand Everything To It's Niche: If It's non-fiction self help link the books together with a brand.  If it's mystery make sure the covers--even with unrelated novels--have similarities that are charateristic of your novels.  Romance same thing.

Am I missing something?  Is there anything else that I haven't gotten to?  Are there anything else you're planning to do?
