What is SEO optimization

SEO optimization is the process of improving the visibility of a website or web page in a search engine’s unpaid results—often referred to as „natural,” „organic,” or „earned” results. SEO optimization typically involves making changes to the HTML source code of a website, as well as associated coding such as Cascading Style Sheets (CSS) and scripting. SEO optimization may also involve optimizing content and HTML tags, improving the website’s navigation and structure, and increasing the website’s overall relevance to specific keywords and phrases.
