Search Engine Optimization (SEO) is the practice of optimizing websites, content, and online presence to improve visibility on search engine results pages (SERPs). It involves a combination of technical and creative elements to attract more organic traffic and improve rankings on platforms like Google, Bing, and Yahoo. SEO can be divided into several key areas, including on-page SEO, off-page SEO, technical SEO, and local SEO. On-page SEO focuses on optimizing individual web pages for specific keywords and user intent by incorporating relevant content, title tags, meta descriptions, header tags, and keyword optimization. Additionally, high-quality, engaging, and original content plays a crucial role in ranking higher on search engines. Off-page SEO involves building backlinks, social media engagement, and other external factors that contribute to a website's authority and credibility.
