seo优化的Web应用程序资源

More than 50,000个学习资源以pdf格式提供, pages, and markdown files were made freely accessible as a website in a structured manner. The traditional web apps created with Angular and React were heavy for mobile users and not SEO-friendly. 因此，我们使用Next.基于React的静态站点生成(SSG)功能, which statically created all those web pages and later delivered from CDN for better speed.

这需要深入了解SEO优化，包括:
•使所有图像加载速度更快与WEBP格式，
•手动生成站点地图XML文件，并通知谷歌搜索控制台，
• setting up our content management system (CMS) for content ingestion of those resources,
•使用webpack进一步缩小和丑化内容，
•在不使服务器过载的情况下重新验证这些静态页面
•为每个页面设置相应的元标签.
