Another thing you might want to consider is to just contribute to this very community.
Read other people's stuff, comment on it, make acquaintances, write reviews on here (honest and fair reviews that are helpful to prospective readers), get to know other authors and their work. Participate in the little seasonal events some people host on here some times, like the April Fool's swap. It's helpful and interesting in a lot of ways, but it also has the side effect that people will be curious about your work from seeing you here.
I got a bump in readership a few months ago beccause I wrote a couple of generally well-received reviews of serials that I had been reading at the time. (Sadly I do not have as much time to do so again.) I'm currently getting a pretty sizable bump in views and readers because I participated in a guest posting opportunity provided by a fellow author on this board. I didn't come here just to advertise anything. I read this forum because I find it interesting to see a perspective different from my personal bubble. But being sociable just helps a lot in general, I've found.
