Before starting your own blog, you need to view others and learn how they work. Different free services can be used to start your own blog and you should look into all of them before selecting one.
Sit down and determine the tone and content of your blog. You can write on different topics but there has to be a consistency in opinion, preferences and writing quality in order to give you blog a personality.
Depending on your content, you also need to have a clear picture of the audience you are targeting. Make sure your content is easily available to those who may be looking for it.
Keep up with recent happenings all around the world and inculcate events and news in your blog posts. Your content will have more credibility if it is based on reality and gives people another perspective on what is happening around them.
While variety is good, try to stick to a specific style or content for your blog. If you write on fashion for instance, people will start visiting your blog and recommending it to others who have similar interests. Eventually your blog will have an identity of its own, which you will need to maintain.
You also need to post regularly on your blog. If you want people to follow your writing you will have to make them come back for more. If you don't update your blog for long, people will assume you are inactive and will stop visiting it.
Encourage comments and debates in your piece. Ask readers for opinions and feedback in order to engage them and maintain their interests. This will also ensure a greater following for your blog.
It is always good to link references in your writing. If you are quoting someone or writing about a certain event, link your readers to it so they can better understand the context of your content.
