How narrow or broad should a niche be?
I'm considering the personal finance niche. I want to cover a range of topics - basic stock market information, investing, money management, etc.
But I also want to include sections on generating money - drop shipping, affiliate marketing, etc
Is this content range too broad for one website?
EDIT: I have decided to go with separate domains for each sub-niche. I just need to decide whether to brand them seperately as well.
