Search Engine Optimization (SEO) is the practice of optimizing websites to improve their visibility and ranking in search engine results pages (SERPs). By optimizing various aspects of a website, such as its content, structure, and links, SEO aims to increase organic (non-paid) traffic from search engines like Google, Bing, and Yahoo.
SEO is essential for businesses and website owners looking to attract more visitors, increase brand awareness, and generate leads or sales. By understanding and implementing SEO best practices, websites can rank higher in search results, resulting in increased visibility and traffic.
