The master shared: Tips for improving the quality of the express train
When we drive the express train, the first thing we need to do is to cultivate words. The most important thing we focus on is the quality score of keywords. The quality score of keywords is the basis of the entire plan, which is related to your click cost and the weight of your account. So if you want to do a good job in the express train, you must first divide the quality, otherwise the money will be in vain and the store may not be built.
