The companies that win at SEO treat backlinks like they treat pipeline: systematically. One high-authority link from the right domain outperforms a hundred low-quality links. Targeting discipline matters in link building just as much as it does in outbound.

Last Refreshed: March 2026 with updated statistics and tool information.

Link juice (also called link equity) is the SEO value that one web page transmits to another through hyperlinks, directly influencing the recipient page's authority and search engine rankings. Have you heard the term "link juice?" If not, that's okay. Even if you have heard it, you might not really understand what it means. It's an important piece of search engine optimization (SEO) but is often overlooked by busy business leaders and marketers who have a million other things to focus on each day:not to mention that 65% of marketers believe that link building is the most difficult part of SEO. But fear not! This guide will break down what link juice is and why it's crucial for great SEO.

From Thomas Cornelius, Founder & CEO, graph8: "The companies that win at SEO treat backlinks like they treat pipeline: systematically. One high-authority link from the right domain outperforms a hundred low-quality links. Targeting discipline matters in link building just as much as it does in outbound."

The phrase "link juice" refers to the value that one web page transmits to another through links. The links between two pages boost the end site's authority, meaning Google and other search engines will take notice and account for this when determining which position in the search engine results pages (SERPs) a particular page should land on.

You might also hear link juice referred to as link equity. When your business earns backlinks, or inbound linking, from other pages outside of your own URL, you'll generate more link juice. Pairing a strong B2B link-building strategy with consistent content creation is one of the fastest ways to compound domain authority. You can also generate link juice by linking to your own internal URLs by referencing pages such as blogs and product information links. Although this certainly isn't the sole criteria search engines look at, it's one of the more important ones in SEO link building.

In short, the more high-quality links you earn, the more link juice you'll garner in your favor.

Equity moves by graft
Authority source HIGH-TRUST PAGE Backlink THE GRAFT Your site Inner page Blog page LINK EQUITY PASSES THROUGH THE CONNECTION
Link juice is the authority one page passes to another through a hyperlink. The graft can come from an outside backlink or from your own internal links. The quality of the source decides how much sap reaches the page.

Each link offers a particular value:not only to the actual destination page but also to any other linked pages. The value (which is the juice) can then be distributed among different pages linked together. Think about it like a pyramid of glasses:when you pour too much liquid into the top of the pyramid, the water will automatically begin to disperse evenly to the glasses below it.

Here's another example: Consider two websites are identical, except for one thing. Website X gets one link from an outside source, but Website Y has no links. When all other things are precisely equal, Website X will rank higher because it has link juice that's been passed on by an outside site.

Again, don't forget about internal linking. It has been shown to produce higher ranks in many cases. Pairing strong internal links with a proactive SEO outreach strategy gives search engines more signals to follow: and your pages more paths to authority. The more internal or external links that go to your pages, the better off you'll be.

One source, many branches
Site X ONE OUTSIDE LINK Page A Page B Site Y NO OUTSIDE LINK Page A Page B the linked site has authority to distribute
When all else is equal, the page with an outside link has the ranking advantage. Once authority enters the site, internal links decide how that equity divides among the pages connected below it.

PageRank is Google's real assessment of how much authority a given page has, but it's often mistaken with link juice. Not all links produce the power of link juice. You should be targeting sites with high domain authority because those are seen as more trustworthy by Google and other search engines and, thus, generate more link juice.

Google uses PageRank as a ranking signal to determine a page's placement within the SERPs. Again, it's not the only factor, but it's certainly one to pay attention to. It assigns a numerical value to pages and scores them between zero (low-quality) and ten (most authoritative) before the algorithms factor in other elements to determine where a page will be featured when users search for specific terms.

In other words, link juice and PageRank may be related, but they're not the same thing.


Ranking is only half the equation. If your content attracts traffic but doesn't convert, you're building a library, not a pipeline.

Flow is not the score
Link equity AUTHORITY FLOW Informal PageRank PAGE AUTHORITY SIGNAL 0-10 LOW HIGH related, but not the same thing
The article separates the informal language from the ranking signal. Link juice describes the authority flow. PageRank is Google's page-level assessment, historically discussed as a 0 to 10 score before other ranking factors are applied.

When the search engines analyze the links that point to your site, they're going to consider a few things, such as:

  • Significance: Is the content relevant to what people seek when they search for specific terms?
  • Trustworthiness: Search engines prioritize the most trusted sources.
  • Follow references: Google won't identify your site with the linking page if you use nofollow links.
  • Crawlability: If Google can't crawl your link, it won't pass.
  • Location: Search engines use site architecture to determine which elements are most valuable to visitors. Sometimes, footer links may not be as beneficial as links within the body of the content itself.
  • Quantity: If there are a million other links on a page, the link you're going for will probably lose its value.

A lot goes into link equity, but these are a few things the search engines are looking at when deciding where to rank your site's pages.

Search engines do not treat every link equally. The article names six checks that decide whether equity passes: relevance, trust, follow status, crawlability, placement in the page, and how many other links share the same source.

What Is Domain Authority?

We've mentioned "authority" a few times, so let's cut to the chase and dive right into this big topic. "Domain authority" (also sometimes just referred to as "authority") is something every site has:some have more than others. It's a search engine ranking score that Moz developed. It's used to predict how likely a site will rank in the SERPs.

According to the uSERP State of Link Building report, 65% of marketers believe domain authority/domain rating is the most important metric for backlink quality. Sites with high domain authority are seen as more likely to appear at the top of search engine results pages.

In contrast, those with low domain authority will likely find themselves pages and pages back when someone searches for applicable keywords.

Moz developed domain authority to estimate how likely a site is to rank. The article also cites uSERP: 65 percent of marketers say domain authority or domain rating is the most important backlink quality metric.

Now that you understand a little more about what link juice is, you're probably wondering if there's anything you can do to enhance your site's organic standing through link juice. While algorithms are a mysterious engine that works behind the screens, there are some things for you to be aware of:

1. Nofollow links

Way back when (it actually wasn't that long ago!), digital strategists would create nofollow links for pages they didn't want to direct authority rankings. The goal was to direct available authority toward specific links. However, when Google updated its algorithm, this technique became obsolete. Now, all links are considered, but the percentage attributed to the nofollow links is wasted.

2. 404 errors

The more blogs and pages you have, the more possible it will be for you to link to a page that no longer exists, which results in a 404 page. If you delete any pages, you need to double-check to ensure you also remove any links that link back to that page. If you don't, the user will see a resulting 404 page, which is frustrating to humans, but it will also cause the search engines to view your site negatively.

3. Duplicate content

An estimated 90% of marketers use content pieces as their main way to generate more backlinks. Yet, you never want to use the same content on multiple pages on your site; your content needs to be completely original and unique across the board, without any sort of plagiarism. If your content is too similar, the search engines will consider it duplicated, meaning only one of the two pages will be chosen to showcase in the SERPs, and you won't have a say over which page gets selected. The best way to ensure your content's uniqueness is to get your content checked via a good plagiarism checker before publishing it online.

4. Disavow

You can get backlinks from any site on the internet, which means, sometimes, you may get "credit" from an unreliable source. Usually, search engines can distinguish good sites from bad ones, but it's still up to you to check and see where your backlinks are coming from. If you happen to get a link from a site that can damage your site's reputation, use the Reject link (disavow link) in Google's tools to eliminate the unwanted follow.

Four ways equity leaks

The article's risk list is operational: nofollow can waste authority, 404s break the path, duplicate content splits which page search engines show, and disavow is the cut you make when a bad source can damage the site.

Frequently Asked Questions

Do nofollow links pass any link juice?

Nofollow links do not pass traditional link juice or authority to the linked page. However, Google treats the nofollow attribute as a "hint" rather than a directive since 2019, meaning some value may still be considered. Nofollow links still provide brand exposure and referral traffic, making them worthwhile even without direct SEO equity transfer.

How many backlinks do you need to rank on Google?

There is no fixed number since it depends on your niche competition, keyword difficulty, and the authority of linking sites. A single backlink from a high-authority domain like Forbes or HubSpot can outweigh dozens of links from low-quality sites. Focus on earning quality dofollow links from relevant, trusted sources rather than chasing volume.

Can internal links generate link juice?

Yes, internal links distribute link juice throughout your website. When an external site links to one of your pages, that authority flows to internally linked pages as well. Strategic internal linking helps search engines discover and rank your most important content by spreading equity across your site architecture.
