①Invest in products, invest in 5-10 plans for one product, and observe the data performance within 6 hours. There is no display (continue to observe after the day, and start a new plan the next day), there is display but no conversion (consume more than 2 times the bid, close it and start a new plan), there is conversion exceeding the cost (3-5 orders are completed and the bid is directly pressed to the affordable range)

②Invest in Douyin live broadcast room: before the broadcast, start 2 types (rapid, professional) and 3 conversion goals (enter the live broadcast room, click on the live broadcast room, place an order) plan (that is, a total of 6 plans, with a budget of 300), use this as a set of standard plans, and then copy two sets of plans again (so there are a total of 18 plans, suspend 7-18 plans when the broadcast starts, that is, only invest 1-6 plans, and start a set of 6 plans every 20 minutes after the broadcast starts. The plan with good data performance (see ROI) can be directly copied to the new plan with good performance)
