To start generating traffic, you must post frequently, say short things that are valuable but easy to digest, and have a clear theme/topic of your blog, that some like minded people will want more information on.
If you keep at it, you will find that your traffic is level, with periodic jumps that make your graph look more like stairs than a slide.
This blog is on the third step. The first one was a baby step, then we started getting 50ish people per day, and then we got noticed by some amazing bloggers, newsletters and websites. We seemed to hit a critical mass in the last couple of weeks which is generating a lot of traffic.
Yesterday WOMMA had a link to us in their email newsletter, and we appreciate that. They are an important resource we use.
Blogs really are like exercise. 20 minutes a day, once a month does no good. 20 minutes a day 4-7 days a week and you are going to be pleased with the results.
