What is SEO (Search Engine Optimization)?

The practice of optimizing websites to rank higher in search engine results, increasing organic traffic.

SEO encompasses technical optimization (site speed, mobile-friendliness, structured data), on-page factors (keywords, meta tags, content quality, headings), and off-page factors (backlinks, social signals, domain authority).

Technical SEO includes proper HTML semantics, JSON-LD schema markup, XML sitemaps, robots.txt, canonical URLs, and Core Web Vitals. Content SEO focuses on providing value, targeting search intent, and maintaining freshness.
