SEO stands for Search Engine Optimization. It is a set of practices and techniques aimed at improving a website's visibility on search engines like Google. The goal of SEO is to increase the quantity and quality of traffic to a website through organic search results.

SEO involves optimizing various elements of a website, including its content, structure, and HTML code, to make it more attractive to search engines. This includes using relevant keywords in content, creating high-quality and valuable content, optimizing meta tags, improving website speed and mobile-friendliness, building high-quality backlinks, and ensuring a positive user experience.

The ultimate aim of SEO is to enhance a website's ranking on search engine results pages (SERPs) for specific keywords or phrases. Higher rankings can lead to increased visibility, more traffic, and potentially more conversions or sales for businesses. SEO is an ongoing process, as search engine algorithms evolve, and websites need to adapt to stay competitive in search rankings.
