SEO, or Search Engine Optimization, is optimizing your website and online content to improve its visibility in search engine results pages (SERPs). It makes your website more attractive to search engines like Google, Bing, and Yahoo, increasing your chances of ranking higher when users search for relevant keywords or phrases. SEO involves various strategies, including optimizing on-page elements such as keywords, meta tags, content quality, and off-page factors like backlinks and social signals. Search engines use complex algorithms to determine rankings, considering relevance, authority, and user experience. Successful SEO involves continuous monitoring, adjustments, and the creation of high-quality, valuable content that aligns with user intent, all aimed at improving your website's ranking and driving organic traffic.
