SEO Fundamentals
Core principles and execution methods of search engine optimization
SEO is broadly divided into On-page SEO (content, meta tags, internal links), Off-page SEO (backlinks, social signals), and Technical SEO (speed, mobile, structured data).
High-quality content meeting Google's E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) criteria is key.
With the emergence of AI search (SGE, Perplexity, etc.), we must now also consider GEO (Generative Engine Optimization).
