Also, novelists don’t need to discuss their marketing plan or platform. Sometimes you might mention your website or blog, especially if you feel confident about its presentation. The truth is the agent/editor is going to Google you anyway, and find your website/blog whether you mention it or not (unless you’re writing under a different name). Keep in mind that having an online presence helps show you’ll likely be a good marketer and promoter of your work—especially if you have a sizable readership already—but it doesn’t say anything about your ability to write a great story. That said, if you have 100,000+ fans/readers on Wattpad or at your blog, that should be in your query letter.
