Please webmasters, I need your kind advice.

Being blogging for a while on the make money online niche.

The niche is totally competitive, and my bog is struggling to get traffic.
Even low competition keywords are competitive here.

Now someone says the best I could do to get traffic in MMO niche is to niche down to a specific country.

Note that, I was writing generally without country specific before.

I'm thinking of Canada or Australia.

What's your thought about this? Kindly advice me.

Note, I'm having upto 150 blog posts many of which are long-form contents.
