Create Your Blogger.com Account

Before you create the blog, you need to figure out what topic the blog will focus on. Think about your skills or hobbies that you’re really good at. You might not be a mechanic, but if you’re really good at working on cars on the weekend, and you love to do it, that would make a great blog topic. Brainstorm your skills and interests to determine what you would enjoy writing about. It’s important that you like to write about it, since you will have to do so to build up the blog!
I will say this: If you have some knowledge on a commercial or industrial topic, this will usually get higher paying adsense ads. But a hobby blog can do very well also (I know this from experience!).

Create the Blog .
Once you have a topic chosen, it only takes about 5 minutes to setup a blog. From the Blogger homepage click the “Create Your Blog Now” link and follow the blog wizard instructions. I won’t get into detail about them because it’s pretty straight-forward, but there are a few points I want to make.
First of all, when you choose your blog URL, make sure that the URL contains the keywords for your topic. For example, if you’re creating a blog about health insurance, “healthinsurance.blogspot.com” is ideal, or “health-insurance” or even “health-insurance-blog” or “health-insurance-12345”. Just make sure that your keywords are in the URL, that will help you be found when people search for your keywords in the search engines.
Also, be sure to pick one of the professional looking templates. I suggest you just pick the plain-white one that is first in the list of templates when you're creating the blog. Once the blog is created, then click on the "Templates" tab and select one of the nicer ones shown there. I'm not sure why Blogger doesn't show you all of the available templates in the blog setup wizard, but they don't.
