The annual income of online novelists varied according to the region, the type of work, the frequency of writing, and the audience. Generally speaking, the annual income depends on many factors such as: 1. Type of work: Different types of novels have different audiences and different income. For example, a popular novel might bring huge traffic and profits, while a niche novel might only have a small traffic and low profits. 2. Writing frequency: Writing frequency is also one of the factors that affect an author's income. Hardworking writers usually earn more because their works are more easily discovered and recommended by readers. 3. Audience: The audience is also one of the factors that affect an author's income. For certain types of works, such as popular online novels, the reader base was very large and the income was relatively high. For other types of works, such as niche novels, the reader group might be smaller and the income might be lower. In summary, the annual income of online novelists varied due to many factors, and it was difficult to give a specific figure. But some successful novelists could earn millions of dollars or more.
