On-page SEO refers to all search engine optimization measures that are implemented directly on your own website. These include meta tags, heading structures, content quality, internal linking, and technical aspects such as page speed and mobile-friendly design. The aim is to prepare the page in a way that makes it easy for search engines to understand and easy for users to navigate. Unlike off-page optimization, which focuses on external factors such as backlinks, website owners can directly influence on-page optimization themselves.
