A lot is being said in the Twitterverse about the subject of writer publicity and promotion. How to build an author platform, how to promote your book, blah, blah, blah.
For one, I find it terribly annoying to be constantly peppered with requests from people to become a fan of their unpublished selves, or their unpublished novels on Facebook. I find it equally annoying to follow an author’s blog or twitter account or whatever when all they do is promote their own material.
Promotion is not as cheap as all that.
If you want people to follow your blog, you should make interesting posts. The subject is not terribly relevant, but it can’t be constantly about new books you have coming out, or, even more annoying, raving reviews your work has received.
A blog offers your readers (whether you’re published or not) an insight into whatever aspect of your life you choose to share. This could be writing technicalities, as done by Ilona Andrews. It could be tv, movies and aspects of society (or your cats) as done in the very entertaining blog of John Scalzi. There are excellent blogs by writers as yet unpublished, such as the services and quizzes for writers by John Gibbs.
The point is, if you want people to follow you in the blogosphere, you have to give them content. Advertising is not content.
