Blogs are a great tool. They allow you to add new, fresh content to your site. They are also a great way to build readership. Think about all the blogs you read. I'm sure that if you're reading this, you're also likely subscribed to a few or at least check them on a daily to weekly basis. Why? Is it because it is entertaining, informative or both? Blogs have been given a bad name because of splogs. Darren Rowse has a terrffic blog (http://www.problogger.net.) where he posts daily with tips for bloggers. Darren has discussed the "Habits of Highly Effective Bloggers", which consist of tips from highly successful bloggers who tell you what they do and make suggesstions as to what you should do.
So, how does all this help you get one way backlinks. Preferrably, you want people to link to you naturally. The best way to do that is to give them something worth linking to. Let's say I was an MS Office guru. My blog might be about relatively unknown tips and tricks on how to use MS office or for creating calenders and spreadsheets. Many people who work with MS office would be interested in that. They may like the tips so much that they list it on their blog or site.
What makes a good blog? Information? Yes! Consistency? Absolutely! However a great blog has to have its own style and flare. A blog that invites its readers to participate in the post is a golden rule. That's almost a guaranteed way to ensure that people will be coming back for more.
If you want to get traffic to your blog, one of the best ways is to leave comments on other blogs. Keep in mind, however, that it has to be done in a smart way. People can always tell when something is spam, so avoid being so obvious. Limit your posts to those blogs that are at least somewhat related to your blog. If a blog is about automobiles and you try to plug your aquarium business, you'll do more harm than good. Go to blogs that are related and take part in the discussion. The more informative and intellectual your comments are, the better chance your post will stay around long enough to be read. That is how you can start to build your readership. If you can convince people what you have to say is worth reading, they will come and read it.
Regardless of what you do to get people to your blog, the proof is always in the pudding. If you can't keep them coming back, all the advertising and work you put into creating traffic will mean nothing.
