Link juice in SEO refers to the value or authority passed from one website to another through hyperlinks. It is a crucial factor in search engine optimization, as search engines use the quality and quantity of backlinks to determine the credibility and relevance of a website. The more high-quality and relevant links a website has, the more link juice it receives, which can improve its search engine ranking and visibility. However, not all links are created equal, and link juice can also be affected by factors such as the authority and relevance of the linking website. In short, link juice is the fuel that drives a website’s online presence and can greatly impact its success in the digital world.
