解决方法
Meta Description Tag Length: It’s not@H_301_8@ the number of words that count. It’s@H_301_8@ actually the number of characters@H_301_8@ length. Because,Google will cut off@H_301_8@ anything more than 155(roughly)@H_301_8@ characters. Optimizing for in the@H_301_8@ description and try to limit its@H_301_8@ length to 25-30 words. Also try to use@H_301_8@ no more than two sentences.
