What Makes a Niche Blog Successful?

We had an overview of niche blogging in the previous post. The idea behind niche blogging is that you focus on a specific topic and throw all your efforts into writing about this topic. Also, monetization is all part and parcel of niche blogging. Before we go into the nitty gritty of this type of blogging, I thought that it would be good to get a general idea of the characteristics of a good niche blog. There are many points to consider in this respect. I like how they have been summarized in Dosh Dosh:

1. Laser-focused Content. The niche blog has a very tight content focus and all of its blog posts must be strongly related to the niche while only occasionally including material in the general field from which it is drawn.
2. Small Scope. The niche blog has a small content scope, which allows it to easily go in depth on the chosen topic and dominate it.
3. Unique Material. While niche blogs can be created through feed-based aggregation of content via search engines or other blogs, they have more long term value for visitors if they offer content that is unique and currently unpublished on other websites.
4. Monetization-friendly Blog Template. Basically, you’ll need a fairly unique blog template that is easily customizable and flexible enough to accommodate heavy monetization.
5. Has an audience. It is important to choose a niche that actually has an audience, no matter how small. Ideally, the niche should be one that will naturally receive search engine visitors over time.

I think that the first two items are quite similar and could be combined – but it doesn’t matter. The important thing is that you understand that your niche blog has to be very very specific.
What do you think, can you create and maintain such a blog?
