Link Equity

Link equity is the authority or ranking value that a hyperlink passes from one page to another. Search engines like Google use it as one signal among many when deciding where a page should rank. The informal term "link juice" is common, but I prefer the more precise phrase because it reminds us that equity is not a fixed currency — it depends on context.

Both dofollow links and internal links can pass equity. Nofollow links, by default, do not, though Google has said it may sometimes treat them as hints. The key point: equity is not a binary yes/no. It flows in degrees, and the amount transferred depends on several factors I'll cover next.

Think of link equity like water flowing through a branching pipe system. A page has a certain amount of equity based on its own authority and the links pointing to it. That equity is then divided among all the outgoing links on that page. A page with 100 outbound links passes less per link than a page with only five.

The main factors that influence how much equity a single link passes: Source authority — links from pages with high domain authority proxies tend to carry more weight. Topical relevance — a link from a page about SEO to another SEO page is stronger than a link from a recipe blog. Link placement — links in the main content body usually pass more than footer or sidebar links. And the number of outbound links on the source page, as I mentioned.

Third-party tools like Moz, Ahrefs, and Majestic have built metrics to estimate link equity: Domain Authority (DA), Page Authority (PA), URL Rating (UR), Trust Flow, and so on. These are useful directional signals, but they are not Google's internal calculations. I've seen sites with high DA that rank poorly because the links are irrelevant or the content is thin.

If you rely solely on these proxies, you risk chasing numbers instead of real value. For a deeper comparison of these metrics, see DA vs DR: Key Differences in SEO Metrics. Treat them as educated guesses, not truth.

Understanding link equity helps you make smarter decisions about where to invest your time and budget. First, prioritize high-quality backlinks over a high volume of weak ones. One link from a relevant, authoritative page can pass more equity than dozens of low-tier directory links.

Second, use internal links strategically. Funnel equity toward your most important pages — your money pages, cornerstone content, or conversion points. A well-structured internal link profile can amplify the value of external links. Third, run regular backlink audits to identify and disavow toxic links that might dilute your equity or trigger manual actions.

Finally, remember that equity is just one piece of the ranking puzzle. Content relevance, user experience, and technical SEO all matter. Link equity amplifies good work; it doesn't replace it.

The most common mistake I see is treating link equity like a commodity you can buy. Buying backlinks from link farms, private blog networks, or mass guest-post schemes violates Google's spam policies and often delivers low-quality equity that can get your site penalized. Even if the links pass some temporary value, the risk is not worth it.

Other missteps include over-optimizing anchor text (e.g., using the exact keyword every time), building links too quickly (unnatural velocity), and ignoring nofollow links entirely. Nofollow links don't pass equity in the traditional sense, but they can still drive traffic and brand exposure. And sometimes Google still counts them as hints.

If you suspect you've accumulated bad links, use the disavow tool carefully. But prevention is better than cleanup.
