One of the tricks to getting anywhere with online writing is to write continuously. What you write and how well you write it matters too, but only in as much as it’s something that matters to you.
If you care about what you’re doing it usually shows through in the doing. People pick up on that, and it gives your writing (and what you’re writing about, whatever that might be) a certain kind of power. A certain gravitas. Makes it more likely to catch someone’s eye and more likely to make an impact on those who do read it. Potential readership and higher impact amounts to a win win.
To me that’s stating the obvious though and none of it matters if you don’t write continuously.
