Before starting a blog one must know the purpose of the blog. Is it for personal or professional use? Is it to build an online portfolio, to promote a product or service, to earn money, to keep updated with the latest trends or to simply keep you abreast of current events and happenings? Once you know the purpose, your next step is to choose a topic to write about.
Since there are literally thousands of blogs on the Internet, there is bound to be one that is exactly what you are looking for. However, starting one that has been forgotten by everyone else may prove difficult. One of the easiest ways of choosing a topic is to think of a particular hobby or interest you have. For instance, if you enjoy bird watching you could start a blog about bird watching in general. If you are very into stamp collecting you could start a blog about stamp collecting.
Once you have decided on a topic, you need to choose a name for your blog. It would be a good idea to choose a name that relates to the content of your blog at least in some way. It would also be a good idea to register the domain name with the biggest search engines. Once you have done this you can set up your blog for publishing and start writing!
