Deciding on a theme can be a daunting task. What exactly are you going to write about? Your niche needs to be a popular topic that many people are interested in.

If you are going to blog about yourself, then you better have a very interesting life, or you will have difficulty keeping your readers coming back for more. You should choose a topic that will make it comparatively easy to grow your readership and build a strong following.

Since many bloggers write about their favorite subjects, it's not a bad idea to start brainstorming by writing down a list of your hobbies, interests, and any areas of professional expertise. Now try to determine a niche you can target within one of those areas.

Should you blog about automobiles in general, or the latest sports cars? If you choose too narrow a theme then you may struggle to come up with regular, fresh content. And if you choose a topic that's too general your readers may be confused by a jumble of seemingly unrelated posts.

You might consider niches within the following general topic areas which have proven to be popular for blogging:

 Automobiles

 Computers & Information Technology

 Digital Cameras

 Gadgets

 Music

 News

 Photography

 Politics

 Shopping

If you plan to use Pay-Per-Click advertising to get traffic to your blog, then remember also that the hottest topics might have the highest pay-per-click fees.

You can sometimes get great niche ideas by browsing at Blog directories and sites like Google Blog Search: http://blogsearch.google.com

Since it is so time-consuming trying to com up with the ‘perfect' niche idea, many bloggers and webmasters have turned to specialized niche discovery tools. I particularly recommend Online Gold Finder and NicheTopics.

With Online Gold Finder you can uncover profitable, undiscovered online markets with just a couple of clicks. Read more about Online Gold Finder at:

NicheTopics is quite handy in a different way. You get to use some great research that's already been completed by an expert. It is a ready-to-use report on 109 unique, untapped niches. Read more about NicheTopics:

The tools above are not free but consider for a moment. If you are planning – or would even like - to make some money from your blog, then it will be worthwhile to start off with a well-researched niche.

If a particular tool uncovers a good niche that pays an additional $5 a day, it will pay for itself inside the first month!

Don't forget, it will be very difficult to change the theme and niche of your blog later. So invest some time wisely during your planning stage.

You will be off to a strong start in building a successful blog.
