Hi Allen,
I currently have a blog (started June 2007) and it is my first attempt at blogging. I have learned a lot over the past 6 months, that I'm sure will help you.
1. You should categorize your posts, as Lisa mentioned. To categorize in Blogger, simply assign a label to the post and then add the
Labels Page Element to your template.
2. You should move your about me above your Adsense code, as well as your archives. The categories should also be near the top. This allows people to browser your blog easier without scrolling below the ads.
3. As Lisa mentioned, sign up with Technorati. This site will also help you see who is linking to your blog.
4. Register your RSS feed with Feedburner (
www.feedburner.com). Feedburner allows you to do much more with your feed. You will also have a new RSS feed through Feedburner that you can distribute instead of your Blogger feed. You can also keep track of your subscribers with Feedburner.
5. Join many of the blog social networks. Blogging is a social medium, and the more active you are, the more successful your blog will become.
6. If you wish to advertise on many of the higher traffic blogs out there, sign up with Entrecard (entrecard.com). Many of the top blogs are registered with Entrecard, and you can easily pay for advertising on those blogs with Entrecard credits.
7. Post on a regular basis and you will slowly, but surely, get more and more visitors.
If I think of other points, I'll let you know.
