As blog writers, I assume many of us are also active blog readers. This is very beneficial as we can look at our blog posts from two perspectives, one of which is more objective than the other. If you are not following a considerable number of blogs right now, go do it! Starting with this one!
While getting your name out there is relatively easy (see my post on advertising for some ideas) getting people to read, and continue to read is different. I do not read every blog that show up in my news feed. Some just don't appeal to me.
The best way to get regular readers in my opinion is to first have a way for your readers to get to your blog, or even better, for them to see when it has been updated without going to your blog first. Since only the title and the first few sentences will probably be shown, it needs to be eye-catching. Include a photo as well. Finally, update regularlarly so that your readers will not forget you, reply to comments, and make sure your writing is worth reading. Also, consider a statistics meter. I recomend Google Analytics. This gives you a count of who is coming to your site, how they are getting there, even how much time they spend there and how many pages they view.
What makes you want to keep reading a blog?
