1, step 1: collect keywords;

(1, collecting keywords that are constantly derived;

(2) Most people don't know the existing keywords (I don't know that these words have conversion rate);

They are only targeted search products, which will not transform medical plastic surgery and have a weak effect on traffic conversion, and should be removed from the shelves.
