How to make copywriting more trustworthy?

If you want your copy to have a new sense of trust, don't brag about your products, and don't brag from the perspective of a merchant. It's like you have a close relationship with someone, and then you say he is good. It's hard not to think that there is a preference, so you have to convince customers in a seemingly "third party" way:

1, let the authority convince the customer. For example, the endorsement of patents and awards from authoritative organizations, a product recognized by a powerful or famous tycoon, a product certified, inspected and authorized by a formal organization, etc. In short, if you are associated with any authority, use it boldly!

2. Let customers convince customers. Now knowledge payment is everywhere. You can see that every course (not the first release) will be praised by a large number of old students, and some brands will publicize it by interviewing old customers and intercepting online praise. That's it. It's up to you. Only people who have used it will believe it and say yes!

3. Let the data convince customers. In order to show the popularity of the product, you can write and sell the copy of XXXX within half an hour, ranking the top three among similar products; In order to show that the quality is good and the effect is good, you can say what the favorable rate and repurchase rate are; To explain the service number, you can say that you have not complained for five consecutive years. ...

4. Let facts convince customers. Some things are not easy to explain, such as the water absorption effect of menstrual towel, so the experiment of pouring water on menstrual towel was invented in the advertisement. Is there any good way to make skin care products work well? You will see the contrast pictures of the same face before use, one week later and one month later, which are intuitive and convincing, and people can't help but want to believe it. In fact, many other products can also design some experiments to illustrate the quality, which depends on the specific product to play.
