On-page SEO is the practice of optimizing individual web pages to rank higher and earn more relevant traffic in search engines. It encompasses both the content and HTML source code of a page that can be optimized, as opposed to off-page SEO which refers to links and other external signals. Effective on-page SEO helps search engines understand the topic and content of your pages, as well as their value to users, which in turn can lead to better visibility in search results. Key elements include title tags, headings, content quality, page performance, and internal linking strategies. By ensuring these factors are well-executed, on-page SEO makes your website more user-friendly and accessible to search engines, thus enhancing your site’s searchability and potential traffic.
