Edge SEO: Edge SEO refers to the practice of implementing search engine optimization (SEO) techniques at the edge of a website's infrastructure, mainly through serverless technologies and Content Delivery Networks (CDNs). The primary goal of Edge SEO is to optimize the website's content, performance, and user experience by leveraging CDN capabilities, such as caching, A/B testing, and real-time site manipulation, without the need for direct access to the origin server. This approach allows for faster implementation of SEO changes and better scalability for large websites.
