A backlink, also known as an inbound link or incoming link, is a hyperlink that directs from one webpage to another website. In simpler terms, a backlink is a link that is placed on one website and points to another site. Backlinks are crucial in the field of search engine optimization (SEO) because search engines like Google use them as a key factor in determining the authority and relevance of a website.
When one webpage links to another, it is seen as a vote of confidence or endorsement by the linking site towards the linked site. The more high-quality and relevant backlinks a website has from reputable sources, the more likely it is to rank higher in search engine results pages (SERPs). Backlinks are essential for establishing credibility, increasing visibility, and improving organic search rankings for a website.
