On-page SEO refers to the practice of optimizing individual web pages to rank higher and earn more relevant traffic in search engines. This can be achieved through a number of techniques, such as optimizing the content and HTML source code of the page, as well as ensuring that the page is properly formatted and structured so that search engines can easily understand its content.
Some common elements that are usually optimized as part of on-page SEO are the page title tag, headlines, images, and overall content. It's also important to include relevant keywords in these elements, as well as in the meta tags and alt text of images, to indicate to search engines what the page is about.
By optimizing these and other on-page elements, you can improve your website's visibility in search engine results pages (SERPs) and increase the likelihood that your pages will be found and visited by users. This can ultimately lead to more traffic, engagement, and conversions for your website.
