That's because millions of people love blogging. They also see their blogs as an opportunity to make money. So there's this huge interest in this particular niche as well as massive competition.
Occasionally I've wondered whether it was a wise decision to choose such a saturated niche. But I do still think it's worth it. You should always write about a subject you enjoy regardless of its popularity, after all.
Break the subject down
Still, the competition can be overwhelming. So how do you overcome this problem? One way is to break the subject down a bit. For example, the big obsession bloggers have is how to get more targeted traffic. So there are countless posts about how to achieve this.
But if you've got a new blog you'll just never compete for a keyword phrase like "how to get traffic to a blog". So you should focus on just one method of getting traffic, and maybe break it down even further.
Take getting traffic from comments, for example. You could write posts about how best to approach this, answering questions like: Can you do too much commenting? Is daily blog commenting a worthwhile strategy? What are the potential pitfalls of commenting for traffic?
Perhaps there's another angle you can take. And this very post is an example: problems that you encounter when blogging about blogging.
Other questions that suggest themselves include: Is it worth writing a blog about blogging? Which are the best blogs in this particular niche and why?
When you look at a subject in different ways you can generate an unlimited amount of relevant and interesting content.
A big surprise
The endlessness of this particular niche has been a big surprise to me. That's because long ago, when I started to blog, I never thought the subject of blogging itself was all that interesting. I just saw it as a quick and free form of self-publishing. So I would just write posts about all the things that I found interesting, particularly politics.
Now, however, I've discovered that blogging is a whole world unto itself. The way people bring traffic to their blogs; how they establish authority in their respective niches; the methods they use to make money -- these subjects are all fascinating to me now.
And maintaining that fascination is crucial. You must write about what you're genuinely interested in. If you do that you'll constantly be learning new things and experiencing original insights. This will supply you with endless fodder for blog posts -- whether you blog about blogging, or another subject entirely.
