I read an article I found through Twitter on my iPhone and can't seem to find it again, in which the writer made a very good point. She said that most fiction writers are under the impression that by keeping a blog we are building up our "platform" and increasing the number of people that will buy our books. She said that in fact this was wrong. Most writers, myself included, write blogs about writing and our writing life. And for most of us our readers are other writers, not necessarily the people we would expect to buy our books. We're actually doing this entire thing wrong.
Most of my books are for kids and young adults and very few kids or young adults probably read this blog. So I can't continue to think that blogging will increase the readership of my books. This is not to say blogging has not helped me as a writer, it has. I've met an important community of writers from all over the world. I get quite a few people contacting me about various things because of my blog. I still see this blog as an important part of my online presence but I need to readjust my thoughts about it as a way to market my books.
I wonder what other people think. Do you think it is important to be very clear about your readership and build up a web presence that caters to those readers? In my case, should I work on a blog for teens in Southern Africa? Do you think blogging helps to sell your books? I'd be interested to hear.
