On-page SEO is all about optimizing the elements of your website that you have control over, while off-page SEO is focused on increasing your domain authority by creating content and obtaining backlinks from other websites. Off-page optimization is a technique that helps a website improve its ranking on the search engine results page. These ranking factors are not directly controlled by the publisher, and instead work outside the limits of web pages. Off-page optimization is mainly concerned with creating links for SEO purposes.
It is a long-term and time-consuming process, which includes acquiring backlinks from authoritative sites, social networks, and social bookmarks. Off-page factors work in the background to improve search rankings. Off-page SEO refers to all SEO tactics that don't involve updating or publishing content on your website. On-page SEO involves all the on-site techniques you can use to ensure that a web page ranks in a SERP, as well as helping to determine how well it ranks. In simpler terms, on-page SEO covers all the actions you take on your website to affect your search engine ranking. Off-page SEO, on the other hand, occurs outside of your website.
