Backlink

A form of off-page SEO where you earn links from other websites that direct readers to your own site. If somesite.com is listing industry events in marketing, for example, and links out to another.com, anothersite.com will consider that link from somesite.com back to their site to be an inbound link, or backlink.

Backlinks are the backbone of a link building SEO strategy, where websites reach out to other websites to earn links back to their website. Google looks at the number of backlinks to a given site when determining its authority because a high number of backlinks indicates that the content of that website or web page is useful to many people.
