Okay, I'm throwing this out there, and please don't be insulted by the simplicity of the advice, but this is my first week blogging, and this came as revelation to me, so I wanted to share in case it will help someone else out.
Tags! It matter very much that you attach tags to every single post, and that you attach tags that people will search for. At first, I thought that categories play the role that actually belongs to tags. My mistake!
My tag "Writing" seems to be bringing most of my traffic in (don't laugh, I have only about 15-30 people reading my blog thus far, and about 1/3 of it is you guys, I'm sure heh)
So there, in case you didn't know.
