At the risk of slipping into sleazy marketing territory, here's a little tip for fellow authors who run blogs.
When you update your blog, let ping engines know.
A ping engine notifies all the little ping bots - programmes that update search engines - that there's new content on your blog. These programmes head on over, examine the content and catalogue it. Over time, this helps search engines to direct traffic to your site.
Here's two to be getting on with. The first two you can update any time you like. The last one you can only tell once every three days. If you update your blog regularly, make it a habit to notify the ping engines once a week.
