There is no one-size-fits-all answer to this question, as the best way to engage with readers and promote your fiction writing may vary depending on your specific goals. However, there are a few things that fiction authors can do to increase their blog presence and reach potential readers.
First, consider whether or not you have the time and energy to maintain a blog. Unless your goal is to simply promote your work and interact with readers, creating a blog can be time-consuming and require regular maintenance.
If this is not something that you feel compelled to do, then you may want to consider hiring a freelance writer to create a blog for you.
Second, make sure that your blog content is relevant to your audience. Unless you are writing for an obscure audience or Targeting a niche market, make sure that your blog content is interesting and engaging enough for readers to keep coming back.
Try writing about topics that are related to your book or that are of interest to your readers.
Finally, think about ways in which you can promote your blog on social media and other online platforms. Building an online following will help promote your work to a wider audience, and may lead to opportunities for book signings and other promotional events.
If you have any existing fans or followers of your work, be sure to encourage them to subscribe to your blog (especially if you offer exclusive content).
