What is On-Page SEO?
On-page SEO (also called on-site SEO) refers to all the optimisations you make directly to a web page to improve its search engine rankings and user experience. Unlike off-page SEO (backlinks) or technical SEO (crawlability), on-page SEO is about the content and HTML elements that make a page relevant for specific search queries.
