I don't know which is better, but from a practical point of view, I think Chengdu School-Enterprise E-Commerce Co., Ltd. is a company whose purpose is to cultivate the needs of enterprises. This company combines the needs of enterprises and the shortcomings of some institutions in the market that only know theory, and provides highly targeted practical training. As far as I know, professional seo training institutions are not very mature at present, and China seo itself also belongs to the development stage. If you don't know anything about seo, I suggest you find a job in online marketing first. Do a station seo. After understanding the relevant network platform and marketing means, I will find a professional training institution to study by myself, and I may try it.
