# Search Engine Optimization (SEO) Search Engine Optimization (SEO) is the practice of improving a website's visibility and ranking in search engine results pages (SERPs). It encompasses a broad set of techniques including keyword research, on-page optimization (content, meta tags, headings, internal linking), off-page optimization (backlinks, domain authority), and technical SEO (site speed, mobile-friendliness, crawlability, structured data). Core ranking factors include content relevance and quality, backlink profile, user experience signals, and technical health. SEO strategies are typically divided into white-hat (following search engine guidelines) and black-hat (manipulative techniques that risk penalties). With the rise of AI-powered search (e.g., Google AI Overviews, ChatGPT search, Perplexity), SEO is evolving toward [[AI SEO]], where optimizing for LLM-based answer engines becomes increasingly important alongside traditional search. ## References - https://developers.google.com/search/docs/fundamentals/seo-starter-guide ## Related - [[AI SEO]] - [[SEO Tips]] - [[Ahrefs]]
