Abstract
Google is the world's largest search engine. Every update of its algorithm has a huge impact on the Internet. The operation of enterprise websites needs to keep abreast of algorithm updates, and at the same time, formulate a search engine optimization strategy that meets the requirements of the updates, and continue to optimize the website, so that only by gaining more attention and traffic can we create value for the enterprise. This article analyzes the core update algorithms launched by Google in 2020-2023, and formulates reasonable optimization strategies and implementation methods. It also uses the code optimization case of the “How to apply for admission” page on the PCU website as an example to explain the optimization process, and provides reference for website operators.
