I could have just tweeted this post from Writer’s Life.org, but that wouldn’t have brought anyone to my blog.
Ah, I kid. But, there’s some good information in this article. The best advice is this:
Keep them short and sweet – screen readers tend to like to skim read rather than read an entire piece. If your blog posts are all pages and pages long then people will be put off by the idea of reading them. They’ll want the information, but won’t want to have to invest all that time getting to the end of your blog to get it.
