People use blogs as a platform for various reasons.  Some use it for marketing, some for promoting, and some for advertising.  If you have a blog, you need visitors/readers. That's the only way your blog can survive; it is like a life-line. No readers - no blog. That simple!!! So, make people to visit your blog.

There are a number of ways to promote your blog. I would suggest you to avail yourself of these free promotions that are readily available: 

1. Search engine submission 

2. Directory submission 

3. Article submission 

4. Social book marking. 

5. Forum posting

6. Google ad-words programme.
