Many micro-marketing companies are basically deceptive companies, so you should be careful yourself. A company that really knows how to do marketing, how can it do marketing for others, and why not do marketing for itself? When you understand the operation idea of marketing company, you will find that the trading mode of marketing company is expected trading. In other words, as long as you don't know how to do marketing, they will give you a bunch of marketing methods, but those marketing methods are beautiful, but they are really in the water. My advice to you is, just listen to the advice of the marketing company, don't take it seriously. You still have to solve your own problems.
