On-page optimization refers to the techniques used to improve a website's visibility and ranking in search engines. This involves optimizing various elements on a webpage, such as the content, title tags, and meta descriptions. By using relevant keywords and ensuring that the content is valuable and engaging, websites can attract more visitors and provide a better user experience. Another important aspect of on-page optimization is the use of internal links and image alt text. Internal links help guide users to related content within the site, while image alt text improves accessibility and helps search engines understand the images. Together, these strategies enhance a website's overall performance and searchability.
