The quality of online novels was deteriorating due to the following reasons: 1. Lowering the threshold of creation: With the development of network technology, more and more people can easily create novels through the Internet, which makes the threshold of creation lower. Anyone can publish their own novels on the Internet. This resulted in many novels lacking depth and thinking, and were written only for the sake of traffic and clicks. 2. Changes in readers 'needs: As readers' needs constantly change, web novelists need to constantly adapt to readers 'tastes rather than just satisfy their own creative desires. However, because the online literature market was very competitive, many authors did not spend enough time and energy to study the needs of readers, resulting in their novels lacking depth and innovation. 3. The emergence of junk literature: Many web novelists lack creative experience and skills. They may only find inspiration through some junk literature. These libraries are filled with a large number of low-quality novels that lack depth and thought just to pursue traffic and clicks. This caused the overall quality of online novels to decline. 4. Over-commercial: Many web novelists have to pursue commercial success in order to cater to the tastes of readers. This means that they must constantly pursue traffic and clicks instead of spending enough time and energy to improve the quality of their novels. This resulted in many novels lacking depth and thinking, and were written only for the sake of traffic and clicks. In summary, the decline in the quality of online novels was the result of a combination of factors. In order to improve the quality of online novels, authors need to invest more time and energy to study the needs of readers, improve their own creative level, and at the same time, they need to properly control the over-commerce.
