What do you mean by optimizing keywords?

Optimizing keywords is mainly to optimize the quality of keywords and the correlation between keywords and promotion business. The key to optimizing the quality of keywords lies in: creative optimization: increasing the matching degree between creativity and keywords; Landing page optimization: the greater the correlation between the landing page corresponding to each keyword and the main content of the keyword, the higher the quality of the keyword. The correlation between optimized keywords and promotion business mainly lies in the correlation between narrow and broad keywords and promotion business. Personally, I suggest not to use keywords with vague concepts. The keyword matching mode with little relevance to related business determines whether the relevance between search words and promotion business is accurate, so each keyword matching mode is different, or you may find that the money you spend on promotion can't generate consultation.
