What Is On-Page Search Engine Optimisation?
On-Page SEO is the practice of optimizing the content, structure, and on-page elements of individual webpages so search engines can understand their relevance, quality, and intent. It focuses on what’s *on the page*—including text, media, semantic HTML, metadata, and user experience elements. The audit evaluates clarity, keyword alignment, content relevance, engagement signals, and how effectively on-page elements support stronger visibility in both traditional and generative search results.-
