In most cases people advice to start in a narrow niche when you start a blog. But does it help to rank if you stick to a narrow niche? As I see it, when you run a blog on WP google ranks your blog posts as separate pages. And it doesn't really matter if you write all articles within a micro niche or in a broad niche, as long as your pick low hanging fruits (=low competition keywords). What is the advantage of going into a narrow niche then? It seems to me it's more advantageous to go broad since you have more opportunities to find low competition keywords. To make it easier for the discussion, we can take "Solo female backpack travelling in Asia" as a micro niche. And "Travelling in Asia" as a broad niche, as an example.
