Technical SEO and AEO: Foundations and Evolutionary Directions

Technical SEO is the foundational layer of search engine optimization. Key elements include website architecture optimization (clear URL structure, XML sitemap, robots.txt configuration), page rendering strategies (SSR/SSG, dynamic hybrid rendering), and crawl budget management (canonical tags, noindex markers). AEO is the evolutionary direction of SEO, with core strategies including structured Q&A content, Schema.org markup (FAQ/HowTo, etc.), and long-tail keyword optimization to adapt to voice search needs and obtain featured snippets.
