On-page SEO describes the optimization of various elements within a website so that its pages can achieve better rankings in search engines. It is also commonly referred to as ‘on-site SEO’.
On-page SEO encompasses any search engine optimization action that involves modifying the content and HTML source code directly on a web page. This includes technical elements such as internal linking structure, title tag optimization, strategic keyword placement, use of Schema markup, image filenames, and ALT attributes.
Another significant component of on-site SEO is site performance. To improve their on-site SEO, a website owner should prioritize factors like mobile responsiveness and site speed. Overall, the single best way to enhance on-page SEO is to consistently create valuable, high-quality content.
In contrast, off-page (or off-site) SEO refers to tactics that occur externally to the website. These might include generating backlinks through guest blogging, social media SEO efforts, and similar strategies.
