Welcome, jg!
I do agree with what Richard has been saying. Your seo blog especially needs a couple of "click here" links
Something that leads straight to the sign-up form, order form or whatever it is that you want people to click.
Promoting blogs is something that will happen more or less naturally, the most important thing is to keep good content going, so once people get to know your blog, more and more will link to you voluntarily. That will then get you the "real rankings", repeat visitors and word of mouth promotion (all free
)
