You can effectively promote your blog with twitter through following Tips :
1. What you already do :
Tweet out the title and link to your blog to all your followers.
2. What you should also do :
Add in one or two relevant hashtags. Whether you toss a # in front of a keyword in your title or just place one at the end, this will bring up your post when other Twitter users search for information.
3. Take it a step further :
Once you tweet out your blog, do a quick search to see who else is talking about your topic. If they have asked a question or you can relate with something they’ve tweeted, reply to them!
People will want to see who found their conversation interesting, and they will go check out your Twitter feed. They’ll be intrigued when they find that you’ve written a relevant blog.
