I want to tell you that SEO promotion is not an easy task. You need long-term endurance. SEO promotion can be divided into paid promotion and free promotion. If you want to do paid promotion, you can do Baidu bidding and other methods. If you do free promotion, there are many SEO promotion skills that need to be paid attention to in development. Personally, I don't advise you to do it yourself. If you don't do it well, Baidu may lose weight for you. I hope you will be careful. I recommend you to stay in Tianjin.
