Offpage SEO refers to all search engine optimisation measures that are carried out outside of your own website in order to improve the ranking of the website in search engine results. It primarily focuses on building backlinks from other websites to your own website in order to increase the trust and authority of the website.

Offpage SEO can be done in a number of ways, such as creating high-quality content that is relevant to and linked to by other websites, writing guest posts for other websites that link to your own website, or participating in forums or online communities to get links to your website.

It is important to note that offpage SEO is also influenced by other factors, such as the quality of the linking websites and the number of linking websites. Search engines favour high-quality backlinks from authoritative and trustworthy websites, while low-quality backlinks or backlinks from spam websites can worsen a website's ranking or even lead to a search engine penalty.
