SEO (Search Engine Optimization) refers to the practice of optimizing websites or online content to improve their visibility and ranking in search engine results pages (SERPs) for specific keywords or phrases. The goal of SEO is to attract more organic (unpaid) traffic to a website by improving its relevance and authority in the eyes of search engines such as Google, Bing, or Yahoo.
SEO involves a combination of technical and creative elements, including keyword research, content creation and optimization, on-page optimization (such as optimizing page titles, descriptions, and meta tags), off-page optimization (such as building high-quality backlinks from other websites), and user experience optimization. The ultimate objective of SEO is to ensure that a website appears as high as possible in the search engine results for the relevant keywords or phrases, which can drive more traffic, leads, and revenue to the website.
