Link Equity: How Backlink Value Flows (SaaS Guide)

Link equity is the ranking value a backlink passes from one page to another, and most SaaS teams treat it like a number they buy rather than a flow they can steer. That mindset costs them. A link you paid good money for can pass almost nothing if it lands on the wrong page, gets stuck behind a bad redirect, or sits on a page Google never indexes. This guide covers what link equity is, how it moves through your site, where it leaks, and how to point it at the pages that earn signups.

Key takeaways

• Link equity (sometimes called link juice) is the ranking power a page passes through its links. It is rooted in Google's PageRank model, not in third-party scores like DR or DA.
• Equity splits across every followed link on a page and decays a little at each hop, so placement and link count matter.
• It leaks through bad redirects, orphaned pages, noindex tags, and links to URLs Google has not crawled.
• Internal links recycle the equity your backlinks bring in, and the two compound when you route external authority toward money pages.
• A link that is never indexed passes zero equity, so vetting and indexation decide whether a link works or just looks good in a report.

What link equity actually is

Link equity is the share of ranking value that flows from a linking page to the page it points at. When a respected site links to you, it passes a portion of its own authority, helping the target page rank. The concept comes from Google's original PageRank algorithm, which treated a link as a vote and counted votes from important pages as worth more than votes from obscure pages.

That is the part most buyers get. The part they miss: equity is not a fixed deposit. It is a current that moves, splits, weakens, and can drain out of your site if the plumbing is wrong.

A few things shape how much equity a single link carries:

• The authority of the linking page, not just the domain. A link from a thin, ignored page passes less than one from a popular, well-linked page.
• Relevance. A link from a marketing blog to your marketing SaaS beats an off-topic mention.
• Placement. Under Google's "reasonable surfer" patent, a link a real person is likely to click (in the body, with descriptive anchor text) passes more than one buried in a footer.

Link equity vs domain authority

This trips up almost every SaaS buyer. Domain Rating (DR) from Ahrefs and Domain Authority (DA) from Moz are third-party scores that estimate a site's overall backlink strength on a 0 to 100 scale. Google does not use them. They are useful proxies, but they describe a whole domain, not the equity any single page will pass.

Link equity is page-level. A DR 80 site can hand you a near-worthless link if the placement sits on an orphaned, unindexed page, while a DR 45 site with a relevant, well-trafficked article can pass more. For more on why the metrics mislead, see why organic traffic beats DR and DA when buying links and the guide to judging backlink quality before you buy.

How PageRank flows page to page

Picture equity as water in pipes. A page collects authority from links pointing at it, then passes a portion out through its own links. Two rules govern the flow.

Equity splits across outbound links. If a page links to ten places, each gets roughly a tenth (the real model is weighted by click probability, but the splitting idea holds). A page with 100 outbound links dilutes each far more than one with 5. This is why a guest post linking to a couple of relevant sources beats the same link in a roundup pointing at 60.

Equity decays at each hop. PageRank uses a damping factor, and roughly 10 to 15 percent of the value disappears at each step before flowing onward. A backlink to your homepage, then a link to a feature page, then to a sub-feature, loses a slice at every jump. Pages five clicks deep get a thin trickle.

What dilutes or blocks the flow

A few common things change how much equity moves:

Factor	Effect on equity flow
Many links on the source page	Each link gets a smaller share
rel="nofollow" or sponsored/UGC	The link passes no PageRank to the target
Footer/sidebar placement	Lower click probability, so less weight
JavaScript-injected links	May not be seen if Google does not render the page
Deep page depth on your site	More hops, more decay before equity arrives

On nofollow: Matt Cutts confirmed back in 2009 that you cannot hoard equity by slapping nofollow on internal links. The equity assigned to a nofollowed link simply evaporates rather than getting redistributed. Old-school PageRank sculpting through nofollow is dead, so do not waste time on it.

JavaScript matters more than people think. Many SaaS sites are single-page apps, and if your links only appear after a script runs and Google does not render that page, they may not count. Google's guidance on JavaScript SEO is worth a read if your site is framework-heavy.

Where link equity leaks on a SaaS site

This is where money gets wasted. You can buy a perfect link and capture almost none of its value because the equity drains out first. Here are the leaks I see most on SaaS sites.

Bad redirects. Redirects pass equity, but the type matters. A 301 (permanent) passes value cleanly, while redirect chains (A to B to C to D) bleed equity at each hop and slow crawling. If you have ever migrated a site or restructured URLs, this is a prime suspect. We cover the details in 301 vs 302 redirects and preserving backlink value.

Orphaned pages. An orphaned page is one no other page on your site links to. Equity can land there from a backlink, but it gets no internal reinforcement and is crawled rarely. If your money page is orphaned, the authority you earn has nothing flowing into it internally. See broken and orphaned pages that waste link equity for fixes.

Noindex tags. A noindex page passes equity short-term, but John Mueller has confirmed that over time Google treats long-term noindex,follow pages the same as noindex,nofollow. It stops crawling them and the links stop counting.

Uncrawled or unindexed targets. This is the big one for buyers. If Google has not crawled and indexed the page your backlink sits on, the link passes nothing. A link on a page Google has not discovered, or chosen not to index, is a link in name only.

404s and broken targets. If a backlink points at a URL that now returns a 404, that equity is gone and does not redistribute. This happens constantly when teams retire feature pages or change slugs without redirecting.

Internal vs external equity and how they compound

Your link profile has two sources of flow.

External equity comes from backlinks on other sites. This is new authority entering your domain, harder to get and usually what you pay for.

Internal equity is how that authority circulates once inside. Internal links do not create new authority, but they decide where the authority you already have ends up. This is the lever most SaaS teams ignore, and it is free.

Here is how they compound. Say you earn ten strong backlinks, but eight point at blog posts and only two at pricing or product pages. If your blog posts link cleanly into your money pages, the equity that landed on the blog flows toward the pages you care about. If they do not, it stays stranded and your commercial pages stay weak.

Strong internal linking is how you recycle earned authority toward revenue. Our deep dive on internal linking and link sculpting for SaaS authority shows the structures that work.

How to point earned equity at pages that drive signups

You earn most links to top-of-funnel content. The trick is moving that value toward bottom-of-funnel pages:

1. Decide which pages matter. Usually your homepage, top feature pages, pricing, and high-intent comparison pages. These are your equity destinations.
2. Map where your backlinks land. Most point at blog posts and your homepage. Note the gap between where equity arrives and where you want it.
3. Add contextual internal links from link-rich pages to money pages, with descriptive anchor text in the body content, not a footer dump.
4. Shorten the path. Keep commercial pages within two or three clicks of pages that attract links. Fewer hops, less decay.
5. Stop the leaks first. Fix redirect chains, reconnect orphaned pages, and remove stray noindex tags before pouring in more equity.

If you are still deciding which pages deserve the equity, SaaS keyword research for BOFU keywords that convert helps you identify the commercial pages worth strengthening.

Why an unindexed or unvetted link passes zero equity

Everything above assumes Google counts the link. Two conditions have to be true for that.

The page has to be indexed. A backlink only transfers equity once Google has crawled and indexed the page it lives on. If that page never gets indexed, the link is invisible and passes nothing. This is common with low-quality sellers who publish on stale, rarely-crawled sites. See why links must be indexed to count and the reasons backlinks fail to get indexed.

The host site has to be real and trusted. A link on a PBN, link farm, or site with fake traffic passes equity that is worthless or risky. The page might be indexed, but the authority is hollow or about to be discounted by a Google spam update. Equity from a site Google distrusts is equity you cannot bank.

This is why vetting and indexation are not nice-to-haves. They are the difference between a link that flows real value and a line item in a report. At Saaslinks, every site is vetted for genuine organic traffic, and every order is tracked to indexed under a 30-day indexation guarantee. If a link does not get indexed, it has not done its job.

A practical link-equity audit checklist

Run this once a quarter using Google Search Console plus a crawler like Screaming Frog or Ahrefs.

• Find orphaned pages. Crawl your site and cross-reference with your sitemap and analytics to surface pages with no internal links.
• Check your money pages' internal links. Are your pricing and top feature pages getting links from your strongest content? If not, add them.
• Audit redirects. Find 302s that should be 301s and collapse redirect chains into single hops.
• Scan for stray noindex tags on pages you want ranking, and verify backlink targets do not resolve to 404s.
• Confirm new links are indexed. For every link you buy, check the host page is indexed (a site: search works) within a few weeks.

Work through it and you will usually find a few leaks that cost nothing to plug and recover value you already paid for.

Bringing it together

Stop treating link equity as a score you buy and start treating it as a flow you engineer. The strongest backlink does nothing if it sits on an unindexed page, drains through a redirect chain, or lands where your internal links never reach. Vet the source, confirm it indexes, then route the value where it earns revenue.
