Three main reasons to start a blog:
Simple and easy
A blog is easy to set up and maintain. It is very inexpensive and easy to use, both for the reader and the blogger who maintains the blog. WordPress is the most widely used blogging software. It is a database driven program that makes blogging easier and blogging faster. Self-hosted WordPress blogs give the blogger more authority than Blogspot’s free blogs and WordPress.com-hosted blogs. It is basically free WordPress software that runs on your chosen web server. With the prices of web hosting charges lowering, creating a WordPress hosted blog has become quite affordable.
SEO optimized
WordPress blogs are SEO optimized by default. That means search engines take them well. Getting a listing on a search page is vital for traffic. People can find you while looking for something. Writing useful content with related keywords makes your posts rank faster and in prominent places. With WordPress, everything becomes so easy that it can hardly be imagined on blogger or other blogging platforms.
Advertise your content
If you have a business, I recommend that you start a blog. This is very beneficial, regardless of the costs of creating a WordPress blog. A blog has a casual friendly tone and a reader takes it as good advice for buying things from you. Having your own domain makes it easy for you to be accessible. Show your products, give them your contact information for inquiries and when a message appears, give them your quote. Everything is so simple and profitable. But before that, get a WordPress guru to help you set up a blog and help you from time to time.
