What is the process called that affects the visibility of a website in a search engine's organic results?

The correct answer is Search Engine Optimization (SEO). This process involves a series of strategies and techniques aimed at improving a website's visibility in the organic (unpaid) search results of search engines. SEO focuses on optimizing various elements of a website, including content quality, keyword usage, site architecture, and user experience, to make it appealing to both search engines and users.

By implementing effective SEO practices, a website can improve its ranking in search engine results pages (SERPs), making it more likely that users will find it when searching for relevant topics. Key components of SEO include keyword research, on-page optimization (such as meta tags and content), technical SEO (which ensures the site is easily crawlable), and building quality backlinks.

Search Engine Marketing (SEM), while related, refers to paid advertising that appears on search engine results pages, different from the organic strategies used in SEO. Website Performance Enhancement focuses on the technical aspects of how well a site operates, and Web Content Strategy involves planning and managing content creation and publication but does not specifically address visibility in search results.
