Link equity is the SEO value or authority that one page passes to another through a hyperlink. In practical SEO work, it helps determine which pages on a site are more likely to rank because internal and external links can strengthen page importance, improve discovery, and support indexing. When you review a website, checking how link equity flows is useful because strong pages often waste value by linking poorly, while important commercial or informational pages may receive too little support.
How link equity works on a website
Search engines use links as signals of relevance, trust, and page importance. A page with strong backlinks can pass some of that value to other pages through internal links. The amount passed is not equal in every case. It depends on factors such as the linking page's authority, the number of outgoing links, the relevance between pages, and whether the link can be crawled and counted.
For site owners, this means internal linking is not just a navigation choice. It is a way to direct SEO strength toward pages that need visibility. Category pages, service pages, and high-converting guides often benefit when they receive links from pages that already attract backlinks or traffic.
What affects how much equity gets passed
- Links from pages with strong backlinks usually pass more value than links from weak pages.
- Relevant links tend to be more useful than links placed on unrelated pages.
- A page with too many outgoing links may dilute the value passed through each one.
- Links blocked by nofollow, robots rules, or poor crawl paths may pass little or no SEO value.
- Buried pages often receive less internal equity than pages linked from main navigation or key hub pages.
How to check link equity during an SEO review
Start by identifying the pages with the strongest backlink profiles or the highest internal authority in your crawl data. Then compare those pages to the URLs that matter most for search visibility, such as product categories, location pages, or lead-generation pages. If important URLs sit several clicks deep and receive few internal links, they may not be getting enough support.
A common example: a blog post earns several quality backlinks and ranks well, but it does not link to the related service page. Adding a clear internal link from that blog post to the service page can help transfer relevance and authority to a page that is more valuable commercially.
What to improve if link equity is weak
Strengthen internal links from authoritative pages to priority URLs, especially where the topic match is close. Remove unnecessary links from thin or low-value pages, fix orphan pages, and make sure important pages are reachable through crawlable HTML links. If a site has many duplicate or near-duplicate pages, consolidate them so authority is not split across multiple weak URLs. Link equity works best when the site structure is clear, important pages are easy to reach, and links reflect real topical relationships.
