Hey guys,

Ricardo here. I've been doing a bit of research into a couple things for my book I'm writing, and one thing that kept coming up was building an audience.
Upon further research I saw that starting a blog about my book would help with this.

Here are my question:

Would it really be a good idea to start a blog about my book? Characters, inspiration for it, world, things like that.

I know I'm still a long ways off getting my book finished, but I want to create excitement so people will know about it when I publish. I've started a few blogs before this and they've all inevitably failed, any advice as to how to stop it from going belly up?

Any help at all regarding this would be greatly appreciated.
