Link equity is an informal SEO term for the signals pages may pass through links; it is useful for planning internal paths, not a measurable currency.
Link juice is shorthand, not a published metric. It describes the intuition that crawlable links connect pages and may help systems discover relationships. It is not a number that can be poured between URLs.
Practical implementation
Design links around reader tasks and architecture. Give important leaf pages contextual links from relevant hubs, use concise descriptive anchors, and ensure every important page has a normal path. Ask whether each target answers the next question; dense cross-link blocks can obscure the structure.
What to verify
Crawl rendered pages and confirm target pages are reachable from useful hubs. Inspect anchors, final destinations, canonical status and orphan risk. Compare changes with navigation and indexation evidence without assigning a causal score.
Common mistakes
Do not sell or report arbitrary link-equity totals. Placement, target, context and crawlability all matter.
