Deciding what topic to choose for your blog can be a stressful thing especially if you are trying to choose a profitable niche for your blog. So how do you do this? There are many questions to ask and here are some that I would suggest that you might consider in your pre blogging stage.

• Firstly are you interested in the topic that you’re considering? To sustain a blog for the long haul which is what your going to need to do if you want to build a profitable blog you need to have some level of interest in the topic, you need to have something that will drive you back to the keyboard day after day after day for two, three, four, five years in order to build the blog to its potential, so are you interested enough in the topic to see yourself writing at that level for that length of time.
• Do you have any experience in the topic that you want to write about? You don’t have to be an expert in the topic that you blog about as you can research and study the topic and then write about it. However you will have to work even harder so its advisable to choose something that you have experience of and would enjoy writing about.
• What are you going to bring to your blog? Do you know enough about the topic to see others wanting to come and listen to you or read what you have to say about it? Would you listen to yourself on the topic? Try to bring something different to your blog, something that will catch a users attention that will make them want to subscribe to yourblog.
• Can you say something unique about this topic? If there are already other blogs blogging on this topic already can you add something to the conversation or can you add something in a in unique way that will bring something different to it. People won’t be interested in coming to your blog if they have read the same thing before. An example of this is the new blogrush that came out recently. So many bloggers wrote about it thinking they would get traffic but they were wrong because now its old news and people know about it and know how to use it. If you go to digg and search for the keyword you would see that majority of all articles with the blogrush keyword hardly got any votes.
• Is the topic itself popular, is it something that people are searching the web for? If there is no one looking for the information on the topic you want to write about your going to have a difficult time building that blog. Use Google keyword suggestions too to find out if people are searching for it. Study this for a few days to see if you results change over the days. This will determine if the topic is growing or shrinking. For example, if you write a blog related to Christmas you might see a huge niche in this right now but the number of searches will sure decline afterwards.
• What competition is there in that topic? Even if there is competition it doesn’t really matter it just means you will have to work harder.

These are all something’s that you may want to consider before deciding on a topic for your blog
