pay attention to the keyword data of the wireless terminal in recent 3 days. Words that can bring good traffic, stable ranking and good transformation must never move, and it is best not to move even the position! Don't change too many words at a time, just two or three words.
Some long-tail words should not be separated as far as possible, so as not to destroy the accumulated weight. The weight of core keywords will be higher before or after the title, and spaces should be used as little as possible to avoid wasting words. Taobao's word segmentation system will split keywords correctly.
