SEO stands for Search Engine Optimization. It is the practice of optimizing a website to improve its visibility and ranking on search engine results pages. This involves various techniques such as keyword research, on-page optimization, link building, and content creation. The goal of SEO is to drive organic (unpaid) traffic to a website by making it more relevant and authoritative in the eyes of search engines like Google. By implementing SEO strategies, websites can increase their chances of appearing higher in search engine rankings, ultimately leading to more visibility, traffic, and potential customers.
