Search engine optimization (SEO) is a process that involves optimizing webpages to increase their visibility in organic search results. The SEO process involves analyzing a website, removing any errors, optimizing on-page elements like titles, descriptions and content, and conducting off-page activities such as submitting the site to directories and social bookmarking to drive traffic to the site. The goals of SEO are to achieve high rankings on search engines, increase website traffic, and generate more revenue through organic search.
