How to improve the overall content quality of a website by cleaning up low-quality content?

When a website contains a large amount of low-quality content (such as duplicate information, outdated materials, or shallow content), systematic cleanup can effectively improve the overall content quality and user experience. This process enhances search engine trust in the website by removing or optimizing low-value pages and focusing resources on strengthening high-quality content. Identifying low-quality content requires attention to three scenarios: duplicate content: multiple pages containing similar information or copied content; outdated information: data, policies, or cases not updated in a timely manner; low-value pages: thin content lacking depth or disconnected from user needs. Processing methods include: directly deleting valueless pages and submitting dead links; merging theme-related duplicate content into core pages; updating outdated information and supplementing new data or cases. After cleanup, 301 redirects should be used to retain the value of original links and avoid disrupting the user experience. It is recommended to conduct content audits quarterly, identify low-quality content using user behavior data (such as bounce rate and dwell time), and continuously optimize the depth and relevance of high-quality pages to gradually build a high-quality content system.
