On-page SEO and off-page SEO are two different types of SEO techniques used to optimize websites for search engines.

On-page SEO refers to the techniques used to optimize the content and structure of a website's individual pages, including things like title tags, meta descriptions, headers, internal linking, and keyword optimization. The goal of on-page SEO is to make sure that search engines can easily understand the content and relevance of a web page.

Off-page SEO, on the other hand, refers to the techniques used to improve the visibility and ranking of a website on search engine results pages (SERPs) by building external links, social media presence, and other factors that are not directly related to the content of a website. The goal of off-page SEO is to increase the authority and trustworthiness of a website in the eyes of search engines.
