In Internet sales, there are often various product names. The names of products of the same type can have fewer words or longer words. From the perspective of consumer willingness to purchase goods, the word length of a product name (as an external quantitative expression of the amount of information contained) is likely to have different impacts on the final sales results of similar products. In this article, our research will mainly discuss the impact of the word count of product names on product sales. From the perspective of consumer risk perception when purchasing products, analyze the impact of the word count of different types of product names on consumer perception of risk types and the degree of importance attached to these potential risks, and analyze the reasons for different levels of attention. Meanwhile, based on product prices and types, we will collect data through large-scale e-commerce platforms, draw conclusions through analysis, and provide some product name suggestions for merchants of different types of products.
