The first thing you need to do if you plan on making a living off blogging is to start your first blog. Now, there is a large number of places that offer free blog hosting, but the easiest one to work with is Blogger. It is a free sign-up and you can have as many blogs as you like through Blogger which is now owned by Google.
After you have signed up you need to decide on your URL which is basically the address of your blog. For example this site's URL is http://livingoffblogging.blogspot.com another example would be http://worldsfunniestvideo.blogspot.com and so on. You should try and make your URL related to the topics you plan on discussing in your blog, this will help you to get more search engine traffic. Remember though, not all URLs are even available so you might have to get a little creative when it comes to your URL.
So now that you have picked a URL you need a Title for your blog, it doesn't have to be exactly like your URL, but again it helps in the search engines if your Title and URL are at least close to matching. Blogger then has you pick a template for your blog. Don't sweat this too much as you can always change it later. My personal favorite is Minima Black or Stretch, but it is entirely up to you.
Just like that you have created your first blog, congratulations! Now it is time to start posting. I like to start out with a welcome post of sorts, tell your reader what you plan on discussing in your blog or just the purpose of your blog.
The very next thing you should do is begin tracking your blog with Google Analytics. This free service offered by Google tracks all the visitors to your site. To learn how to install Google Analytics in your site just click here! Let me know if you have any questions or problems so far...
