First of all, we should have a clear, concrete and operational plan for "everything is done in advance", because for most websites, optimization means revision, and revision is something that every website must be extremely cautious about. In particular, it is not recommended to optimize websites that have only been established for less than 3 months (they have not passed the inspection period of new websites of search engines such as Baidu and Google) (because the weight of new websites is low, including any major changes in the homepage label, which may cause extreme concern and even punishment of search engines).

"Website Optimization Scheme" should first understand all aspects of its own website (including Baidu snapshot, Baidu Google inclusion, external link inclusion, internal structure of the website, keyword setting, internal link construction, etc. ) and make a comprehensive and objective quantitative analysis. On this basis, the website adjustment (revision) scheme should be put forward, including the expected objectives (best and worst), means and assessment methods (indicators) and emergency measures of website optimization. Then there is the feasibility demonstration of this scheme, consulting several website construction companies or online consultation, and finally modifying and determining the scheme, and finally implementing the scheme.
