On-Page SEO refers to the practice of optimizing individual web pages in order to improve their visibility and ranking in search engine results. On-Page SEO involves optimizing elements such as content, HTML tags, headings, and meta tags, as well as improving the overall user experience (UX) on the page. Some aspects of On-Page SEO overlap with Technical SEO.

On-Page SEO is one of the four pillars of a well-search-optimized website — the other three include Content SEO, Technical SEO, and Off-Page SEO.
