Your theme determines the feeling a reader gets when they see your web site. When you create your web site you have a theme in mind. What is it? What is the mood you are trying to create with it. Remember, it's like your book. Each book has a theme to it.
For example, if your book's genre is Children's Literature, your theme more than likely has bright colors, children playing, cartoons, etc. Fonts, colors, pictures, images of things related to children.
Your book on mystery would have bold fonts, dark colors, a loop, a fedora, a cape, guns, actions images. When someone opens up your website, they automatically know that you write mystery.
That's what you want with your website. When a reader opens your web site they know exactly what you write.
Color scheme consistent throughout all the pages
All pictures are all associated with each other
Font family is consistent
“Successful websites are like books, they’re not born, they are created. It takes time to outline, flesh it out, critique, proof, and publish. Your website needs the same attention as your book. The Ghoster makes it easy for you.”
