A blog is a weblog or a web journal where you can share information about your life with friends, family or the world. If you want an easy-to-create, easy to update and easy to maintain website, a blog may be just the answer.

The first step to blogging is to get yourself a blog. Just as a website needs a domain name and web hosting, your blog will need to have a place on the Internet to live.
You can obtain a free blog from websites such as Blogger.com, which is affiliated with Google. There are also a number of other websites that offer free hosting of your blog and that will allow you to quickly and easily create your blog for free using their graphical interface.
If you want to have a blog that has its own email address- in other words, you don't want the blog to be "yourblog.blogspot.com", you just want it to be "yourblog.com," then you will need to pay for a domain name and web hosting separately and upload blogging software onto that website.
This is a more complicated process and involves you having knowledge of website design or building and computer coding, so this is best for advanced users. However, some sites such as Wordpress.com have programs available where they can help you load their blogging software onto your own domain name so you don't have to be a programming guru to get your blog going.
Before you start blogging, you will need to pick a name for your blog. This is the name that people will type in to get to it and that they will use to find it, so make sure the name is reflective of what you want your blog to be. You also need to ensure that the blog name is not already in use as well.
You can make your blog about anything you want, but if you intend to keep it going over time, make it about something you are passionate about. You also want to think about the purpose of the blog. If you are going to try to make money off of it, you need to make the articles interesting enough that general readers would want to hear about it. If you are just making a blog to share your own feelings or opinions or details about your life with a select few, then the focus will be different.
Regardless of who your audience is, it is a good idea to pay attention to your writing style. No one- even your family members- will likely want to read a blog post that is full of grammatical errors or typos. Proofread and spellcheck, because this blog is going to be published work, even if it is just published for a select few online.
Many people who wonder how to blog as the question because they have heard about people making money from their blogs.
If you created your blog to make money, you need to put some programs or systems in place that will allow you to profit form it. One of the most popular, Adsense by Google, allows you to place ads on the side of your website based on keywords you use in writing. Just sign up for Adsense to get your code and then paste that code into the style sheet of your blog. If you have used Blogger, you can automatically add Adsense as a widget through the design template of blogger.
You can also use affiliate programs wherein you sell items from your blog and get a cut each time the item sells. Other bloggers or stores may also offer you a fee to place a text link or banner ad to their site from your blog, especially if your blog becomes popular and widely read.
