How To Promote Your Blog Posts

1. Post to Twitter
2. Post to Facebook
3. Post to G+
4. Comment on a bunch of commentluv blogs so people can see your recent post
5. Submit it to blog voting sites like http://Bizsugar.com or http://blogengage.com or Hacker News
6. Deep link to other bloggers posts so they will be sent trackback notifications, getting them to your site might get it mentioned elsewhere - engaging with other bloggers is the best way to get your content promoted. 
7. Mention other people and products in your post and send out tweets letting them know they were mentioned. 
8. Get guest bloggers who will often promote the post to their audience (ex / current journalists have a healthy audience)
9. Send an email newsletter to your list with a personalised intro and a link to the blog post (I use MailChimp it's great). 
10. Go into forums that are are active in and look for threads that your post relates to, if rules permit reply with a link to the post. 
11. Update your forum signature every time you release a new post. 
12. Use WiseStamp so your email signature always shows your latest post.
