The basic SEO practice includes a number of modification within a website. All changes made with a website to improve easy crawling, better cache for getting identified by search engine programs are commonly called as on page SEO optimization.

Onpage optimization (AKA on-page SEO) refers to all measures that can be taken directly within the website in order to improve its position in the search rankings. Examples of this include measures to optimize the content or improve the meta description and title tags. Conversely, off-page SEO refers to links and other signals.

On-page SEO is the practice of optimizing individual web pages in order to rank higher and earn more relevant traffic in search engines. On-page refers to both the content and HTML source code of a page that can be optimized, as opposed to off-page SEO which refers to links and other external signals.
