We can use blog for one more purpose. And that is to promote low competitive keywords. Blog also acts as an informal platform for sharing interesting information.
Through blog marketing you could attract more user to your blog. Through these you could get earn on advertising or referral sales strategies as it increases the referral user to your website.
1. Low Cost Marketing Channel
Blogs are cheap - even free. Blogs are easily built into an existing website. Blogs can also be maintained at dedicated hosting sites all over the web for low or no cost. Typically it would be recommended that a web business create their own blog domain for brand awareness purposes. It also looks that much more professional in my opinion.
2. Excellent Avenue to Build a Network
Every business needs a network; an internal network between divisions and an external network with other companies and customers. Staying in contact with so many individuals, however, takes large investments of time. A regular blog on the other hand is quickly written (particularly when you are close to and well versed in your subject matter). Blogs can reach thousands of targeted readers at any time in any place.
When you find that right tone and atmosphere with blogs, you can get people talking with each other about your business. And when that happens, people will share stories and ensure that your site gets lots of traffic.
