SEO, or Search Engine Optimization, is the practice of optimizing a website’s content, structure, and various elements to improve its visibility and ranking in search engine results pages (SERPs). The goal of SEO is to enhance a website’s organic (non-paid) search engine traffic by making it more accessible, relevant, and trustworthy to search engines like Google. SEO involves techniques such as keyword research, on-page optimization, link building, and technical improvements to ensure that a website ranks higher for specific search queries, ultimately driving more relevant traffic to the site.
