Search Engine Optimization (SEO) is the process of optimizing websites to improve their visibility on search engines like Google, Bing, and Yahoo. It involves techniques such as keyword research, on-page optimization (content, meta tags, URL structure), off-page strategies (backlinks, social signals), and technical SEO (site speed, mobile-friendliness, indexing). The goal is to rank higher in search results, drive organic traffic, and enhance user experience. SEO is divided into white hat (ethical, long-term strategies) and black hat (manipulative, risky tactics). With continuous algorithm updates, SEO requires ongoing optimization and content relevance to maintain rankings and grow online presence. 🚀
