Off-page SEO (also called off-site SEO) is a set of tactics used to improve a website's ranking on search engine results pages (SERPs). It involves all the activities that are done outside of the website to influence its SERP rankings. This may include creating backlinks, being active on social media, and blogging as a guest. Off-page optimization is a technique that helps websites increase their visibility on SERPs.
These ranking factors are not directly controlled by the publisher, and they work outside the boundaries of web pages. Off-page optimization mainly focuses on link building for SEO. It is a long-term and time-consuming process, which includes acquiring backlinks from authority sites, social media, and social bookmarks. Off-page factors work in the background to improve search rankings.
Off-page SEO refers to any activity that can potentially affect engine rankings, with link building being the most common example. However, there are many other off-page factors besides links.
