The product selection method for AI graphic and text delivery is as follows:

1. Selected alliance: On short video platforms such as Douyin, you can join the selected alliance, which will recommend some products with high sales and good commissions. Merchants can choose suitable products for delivery according to their own positioning and fan preferences.

2. Third-party e-commerce data platform: You can refer to the sales rankings and popular products of e-commerce platforms such as Taobao and JD.com to select some hot-selling products with good reputation. At the same time, you can pay attention to some industry information and trends to understand the current popular product categories.

3. Hot topics on social media: Pay attention to hot topics and trends on social media to understand user needs and preferences. For example, on Douyin, you can pay attention to hot challenges and topics to dig out products with potential.

4. Crowd positioning: Clarify your target population and understand their needs and consumption habits. For example, for middle-aged men, you can choose some home furnishing and department store products; for young women, you can choose beauty, clothing and other products.

5. Profit considerations: When selecting products, consider the profit margin of the products. Choosing some moderately priced and high-profit products can increase sales and revenue.

6. Product quality: Ensure the quality and reputation of the products to avoid losing fans and bad reviews due to quality problems.

7. Supply chain stability: Establish a stable cooperative relationship with suppliers to ensure sufficient product supply to avoid out-of-stock situations that affect sales.

Combining the above factors, your actual situation and fan preferences, select suitable AI graphic products. At the same time, we must continuously optimize product selection strategies and adjust them according to market changes and fan feedback.
