Some people define a blog as a simplified web site designed to suit and match the individual bloggers' personality.
There is truth to this.
Actually blogs and web sites are pretty much similar.
A blog and a web site can both give you web presence.
Through blogs or web sites, your pages can be viewed on the internet and search engines treat both in the same way.
In starting an online business, you can just use a blog to establish your presence on the web.
It is cheaper and fairly easy to install and create.
You're just starting your business and you will need the extra cash you can save to spend on the other aspects of business.
Blogs also have the advantage of easy content manageability.
Unlike with web sites in which you will need software, a server, and other power tools to keep your site running glitch-free, blogs only need your writing and marketing ability to start it running.
All the tools are provided by the blog hosts.
Most blog hosts offer the service for free but this is usually ad supported, meaning you will allow the host to run banner and text ads to your blog site.
There are upgraded or paid blog sites and the only difference with a free blog is it is ad free and sometimes you get to own a unique domain name.
Blogs are very popular nowadays.
More and more web users are using blogs different and varied reasons.
Some use it as a personal web page and still use it as an online diary while others are using it for productive business ventures.
Those who own a web site use blogs to add value to it and as a complement in their web content delivery.
Other online businesses use blogs to capture email addresses and increase their opt-in subscribers.
Needless to say, blog creation and publishing is slowly taking the place of web site building and web site publishing.
And all of it is for good reasons.
