The purpose of word selection skills on Taobao is to make your products rank higher in the search results, thereby attracting more potential customers.

Here are some word selection skills:

1. Keyword and product relevance: Make sure the keywords are highly relevant to your products. This will help improve the search ranking of your products and attract more targeted potential customers.

2. Search popularity: Choose keywords with high search popularity. You can use tools such as Taobao's "Business Advisor" to view the search popularity and data of keywords in order to understand consumer search behavior.

3. Competition level: Consider the competition level of keywords. Highly competitive keywords may be difficult to improve rankings, but can bring higher traffic. Low-competition keywords, although easy to improve rankings, may have less traffic. Therefore, it is necessary to weigh the competition level and traffic of keywords and choose the right keywords.

4. Long-tail keywords: Using long-tail keywords can improve the targeting of products. Long-tail keywords refer to those keywords that are relatively long, specific, and less competitive. Although they have lower search volumes, they can attract more targeted potential customers.

5. Keyword diversity: Choose multiple types of keywords, including product words, brand words, attribute words, scene words, etc. This helps to cover more potential customers and increase the exposure of your products.

6. Update keywords regularly: Update keywords regularly based on market changes and hot topics. This can help you seize market opportunities and increase the exposure of your products.

7. Test and optimize: Continuously test and optimize keywords. By analyzing data such as the click-through rate and conversion rate of the products, continuously adjust and optimize keywords to achieve better results.

In short, word selection skills need to be comprehensively considered in combination with factors such as product characteristics, market competition, and consumer search behavior. By continuously optimizing and adjusting keywords, the search ranking of products can be improved, thereby bringing in more traffic and sales.
