In Baidu's bidding account, can keywords be deleted at will?

In the Baidu bidding account, can you delete keywords at will? Stopping will keep the star rating of your keywords unchanged. There are many factors that affect keyword quality, such as the quality of creative writing and the relevance between creativity and keywords, etc. Two of the factors that affect quality are account history performance and click-through rate. Part of the account history performance data includes the data of the keyword you want to delete. Click-through rate is click volume/impression volume. The keywords you want to delete must have clicks and impressions, which will affect your keywords.

My personal opinion is that it is for reference only and it is best not to delete it casually. But some people still say that pausing is not good, it is better to delete it. Everyone has their own opinions. Haha, only after practice can you know which one is right. I will delete some words. Why should I keep them if they are not needed? After learning, you should at least give a thumbs up after reading the post, and you can also add it to Taobao! Some words that don’t work well can be deleted and rebuilt! It depends on the actual situation.
