2. **Use data tools such as JD Business Intelligence**: JD Business Intelligence is a data service product provided by JD to third-party merchants, which can help merchants understand the operation data of the store, such as search index, click index, transaction index, etc., so as to analyze store problems.

3. **Use promotion tools**: During non-platform promotion festivals, you can use promotion tools such as single product promotion and full reduction to increase store traffic and attract new customers to place orders.

4. **Learn from the experience of excellent merchants**: Observe other merchants who have done well, understand their page style, product title optimization, promotion settings, etc., and learn from them.

5. **Participate in merchant exchanges**: Join the merchant group, communicate with other merchants, and learn from their experience and skills.

6. **Continuous learning and optimization**: New sellers should continue to learn, understand the dry goods in the e-commerce forum, and find an operation model that suits them according to their actual situation.

7. **Patience and continuous optimization**: Operating a store is a long-term process, which requires continuous accumulation and optimization every day to see significant results.
