Link Equity
Link Equity represents how PageRank value gets divided and passed through each link on a donor page. The total authority gets split among all outbound links. The value each link receives depends on the donor page's authority and how many other links compete for that same equity.
Several factors affect how much link equity flows through each link on a page. Links higher up on the page typically pass more value than those at the bottom. Nofollow/Dofollow attributes control whether equity flows at all. The Anchor Text used and topic relevance between linking and target pages also influence equity quality and quantity.
The original PageRank formula has evolved into a complex system of tweaks and factors. Modern search engines use dozens of signals beyond simple link counting. These include page position, content relevance, and user behavior to calculate how authority flows through Link Building networks and affects Internal Links.
Some links are better than others! A single relevant link from a high-authority page in your niche carries more weight than dozens of low-quality links from unrelated sites.
