The really cool thing about blogs is that it relies heavily on internal SEO to get somewhere. So as long as you are posting stuff that makes some sense, then you’re already doing well enough. But there are other ways to promote your blog and here are 5 effective methods:
.] Article Directories
An article directory is a platform that allows almost anyone to publish their articles for free. Article directories encourage website owners to pull out content from the directory and paste them on websites that lack content, on the condition that the author’s URL is kept at the bottom of the article. So if you write something useful and interesting for article directories, your article could very well end up on somebody’s website and that earns you a backlink to your blog page.
.] Email Signatures
This really works. But if your blog is very personal you might want to think twice about this. Everyone important enough has an email address, and you have the email address of anyone who is important enough to you. Include a link to your blog on your email signature. That way, every time you send someone an email they might have a few minutes to mind your business and visit your blog…and most people enjoy minding their friend’s business.
.] Social Networking (Twitter, Forums, Blogospheres)
A blogosphere is a blog community. It can be a general community where you can find bloggers from all walks of life blogging about everything under the sun, or it can be niche-specific. Many people enjoy reading blog posts and learning about others. So exchange blogging URLs and learn from one another. Many forums also allow you to keep personal links on your signature. Find such forums and start posting. The more you post, the higher the number of potential visitors to your site. Twitter is also another good way of getting your blog link out there. Follow as many people as possible and hope they’re nice enough to follow you back. Post short updates with the entry link to them and you are bound to get more visitors. E.g. “I just attempted to cook eggs and they exploded in the pad. Check them out: http://yourblog[dot]com “.
.] Yahoo Answers
There’s a small secret to this. Aim for level 2 and your links will be clickable hyperlinks. When this happens, you can write as many responses as you can to the questions, and you can leave your blog link under ‘source’. If your answer gets picked as the best one, people who land on the answer page might be convinced that you’ve got all the answers. 
.] Freebies
Freebies always calls for attention. People love free stuff. Nobody’s going to deny that. Give away free eBooks, logos, and anything that might make someone want to return to see if there are more free stuff. They might even tell their friends about a site that gave them something for free. It’s also helps your credibility rating.
These are some of the exceptional ways to promote a blog. I must admit that promotion is very important for a blog to rank well; therefore, it is necessary to know about the promotional methods, as well.
