What is Link Juice?
Link juice is an informal term used in SEO to describe the flow of PageRank (link authority) from one page to another through hyperlinks. When a high-authority page links to another page, it passes a fraction of its PageRank to the linked page, increasing that page ability to rank in search results. The term reflects the conceptual idea that link authority flows through links like liquid, with each link being a pipe that distributes authority from high-authority pages to linked destinations.
How Link Juice Works in SaaS Websites
Understanding link juice helps SaaS companies optimize internal linking for maximum SEO impact. A homepage that receives hundreds of external backlinks accumulates significant PageRank. Every page the homepage links to receives some of that PageRank. Pages linked from many high-authority pages on the site accumulate more PageRank. For SaaS companies, this means: linking frequently from high-traffic blog content to product and pricing pages, including product CTAs in highly-linked pillar pages, and regularly auditing internal links to ensure PageRank flows to commercially important pages rather than being wasted on thin or low-priority content.
Frequently Asked Questions
Does adding more internal links dilute link juice?
Yes. PageRank from a page is divided among all outgoing links on that page, so adding more links from a single page means each individual link passes slightly less PageRank. In practice, this effect is small for typical page link counts (10-30 links). The more important consideration is ensuring that your highest-authority pages (homepage, key pillar content) link strategically to your highest-priority commercial pages rather than distributing links equally across all content.
Can I preserve link juice with nofollow tags?
No. Google 2019 change to nofollow as a hint rather than directive means nofollow tags do not reliably sculpt PageRank flow. Historically, webmasters used nofollow to sculpt PageRank by nofollowing low-priority links. This no longer works reliably. The best approach for link juice optimization is strategic internal linking: ensure your most important pages are linked from your most authoritative pages, and minimize links from authoritative pages to thin or low-priority content.
