When an attorney decides whether to start a blog or not, I always ask them, "Are you really going to spend the time to make your blog successful?" A neglected lawyer blog is worse than having no blog at all.
I stumbled across this article by Foster Web Marketing that has some very good ideas to help lawyers stay on point with blogs.
This article gives 5 points for a successful blog. My two favorite are:
1. Set aside a certain time of day or week dedicated to working on your blog
2. Don't be afraid to invite guest bloggers to help you create blog posts
I had never considered these two suggestions. I recommend you check out the article.
