With a loading time of less than 1.5 seconds on the first screen will bring users a smooth and fast speed experience. What I recommend is that the loading of the first page of the web page should not exceed 2 seconds at most, preferably within 1.5 seconds. Page browsing experience: From the typesetting layout of the webpage, 50% or more of the main content on the first screen, clear structure, clear navigation function, etc. In short, the typesetting layout of the website should be clean and orderly from the moment the user sees the webpage. The main content is also easy to read. Mobile terminal adaptation: The main emphasis here is that the webpages participating in the mobile terminal ranking should be mobile terminal webpages, not PC ones. Many people should pay attention to this. Advertising specifications for landing pages: Limit advertising on the mobile side, explaining what ads should be used and what ads cannot be used. For example, advertisements such as floating telemarketing list advertisements, pop-up advertisements, and screen-covering advertisements that affect users' normal browsing, or cause obstacles to users' browsing, misleading, deceit, or suspected illegal activities are not advisable. Permission Issues: Reduce the Cost of Access to Information for Users When users browse some websites and encounter situations such as reading full text, viewing pictures, watching video content, etc., these websites will prompt users to complete certain actions. For example: registration can only be viewed and other behaviors. It is increasing some costs for users to obtain information. In response to this behavior, Baidu is also under pressure. Below are two small examples provided by Baidu. 1) Users need to log in to view the larger image: In 6 years, the inventory and interpretation of Baidu's search algorithm 2) Users need to log in to view the full content of forum posts: In 6 years, the inventory and interpretation of Baidu's search algorithm 3) Users need to download or open the APP to view the full text: In 6 years, the inventory and interpretation of Baidu's search algorithm How do I view Baidu's actions in the past 6 years? In fact, in the past 6 years, Baidu has regulated the Internet ecology around five major themes, with many regulations and constraints, and more harvests. There are bound to be some ideas of my own that I would like to share with you. This algorithm review mainly focuses on five themes.
