What about a "Financial Minimalism" blog? Even places like the "simple" dollar is pretty busy and cluttered.

You could boil each concept down to it's core fundamentals and then provide the absolute easiest solutions you can come up with.

For instance, instance of have 8 blogs about each facet of diversifying a portfolio, have a single page that explains the mentality behind investing and how to automate it.

Instead of highlighting the "top ten ways to save money," you have ONE highly efficient method that is tied to a solid testimonial (story) where it worked beautifully.

The con would be that a list of 10 would have more keywords and content and therefore more SEO and tools to advertise and affiliate with.

However, a big pro would be that people in your audience would most likely be much more engaged in your niche because you aren't trying to do it all.

The Balance is the only one I've found that's pretty similar to this idea, however, it could definitely be improved upon. Let me know what you think!

I believe that the problem basically is finding a profitable niche in the personal budgeting area.
It becomes super easy to think of blog post ideas. When you do not have a niche, thinking of blog post ideas can become overwhelming. Contrary to what it sounds like, having a single blog niche helps you come up with more blog post ideas. Creating a Blog Content Plan becomes extremely doable. Basically, your Blog niche must solve a major problem being faced worldwide. Once you can narrow down on a niche that does that, you can move on to the next question.
