SEO stands for "Search Engine Optimization." It is the process of optimizing a website or online content to improve its visibility and ranking on search engine results pages (SERPs), such as Google, Bing, or Yahoo. The main goal of SEO is to attract organic (non-paid) traffic to a website by making it more discoverable and accessible to users who are searching for relevant information or services.
SEO is an ongoing process, as search engine algorithms are continually evolving to provide users with the most relevant and useful search results. Keeping up-to-date with best practices and search engine guidelines is crucial for maintaining and improving a website's search visibility.
