Link juice is one of those SEO terms that sounds technical but describes something beautifully simple. Every page on the internet has authority. Links share that authority. Understanding how authority flows through links — and how to direct it where you want it — is one of the most powerful levers in SEO strategy.
Where does link juice originally come from?
Link juice originates from external backlinks — links from other websites pointing to yours. When a respected, authoritative website links to your page, it transfers a portion of its authority to your page. The higher the authority of the linking site and the more relevant it is to your topic, the more link juice it passes.
Think of it as a trust network. Sites that are trusted by many other trusted sites accumulate more authority. When they link to you, they vouch for your site — and that endorsement has measurable value in Google's algorithm.
How does link juice flow through internal links?
Once link juice enters your site through external backlinks, it flows through your internal link structure to every page your high-authority pages link to. Your homepage typically accumulates the most external backlinks and therefore has the most link juice to distribute. Pages linked directly from your homepage receive a large share of that juice. Pages buried several levels deep receive much less.
This is why internal linking strategy matters so much for SEO. By deliberately linking from your high-authority pages to the pages you most want to rank, you direct link juice exactly where it is needed. Use our internal link checker to map how link juice is currently flowing through your site and identify pages that need more internal linking support.
How much link juice does each link pass?
A page's link juice is divided among all the outgoing links on that page. A page with 10 outgoing links passes roughly 1/10 of its available link juice to each destination. A page with 100 outgoing links passes 1/100 to each. This is why excessive linking from a single page dilutes the juice each link passes — and why navigation menus with dozens of links pass less juice per link than a focused in-content recommendation.
What blocks link juice from flowing?
Several things prevent link juice from passing through a link:
- Nofollow attribute — a rel="nofollow" tag tells Google not to pass equity through the link
- 404 errors — link juice flowing to a 404 page is lost. Scan for broken links with our broken link checker.
- Redirect chains — each hop in a redirect chain loses a small amount of juice. Collapse chains to single 301 redirects.
- JavaScript links not crawled — links rendered only through JavaScript may not be crawled and therefore may not pass juice
- Noindex pages — pages blocked from the index do not accumulate or distribute link juice effectively
How do you maximise link juice to your most important pages?
- Build external backlinks to your most important pages — direct link juice from outside sources exactly to the pages that need to rank
- Link internally from high-authority pages — your most visited, most linked-to pages should link to the pages you want to rank
- Fix broken internal links — use our scanner to stop juice flowing to 404 pages
- Reduce unnecessary links on key pages — fewer outgoing links means more juice per destination
- Ensure important pages are within two or three clicks of the homepage — pages buried deep in your architecture receive little juice from the homepage
Summary
- Link juice is the authority passed through hyperlinks — it originates from external backlinks and flows through internal links
- A page's juice is divided among all its outgoing links — fewer links per page means more juice each link passes
- Juice is blocked by nofollow, lost at 404 errors, and diluted by redirect chains
- Direct juice to important pages through strategic internal linking and targeted external link building
- Monitor your internal flow with our link checker and fix leaks with our broken link scanner
