What should I focus on in website development for authors?

[cecilamoore]

I'm planning website development for authors for my own writing website, but I'm unsure which features really matter in the long run. Should I focus more on book pages, a blog, email signups, or something else? I want the website to be useful for readers, not just look good. What has worked for you, and what mistakes should I avoid? I'd really appreciate honest and practical suggestions.
