Internal linking for SaaS sites

External backlinks get the hype. Internal links decide whether Google and humans can walk from “what is this” to “sign up.” SaaS sites break this constantly: blog orphaned from product, docs in another subdomain with no path home, pricing linked only from the nav.

Map hubs, not random links

Pick hubs: homepage, main product page, pricing, docs index, and 3–5 pillar topics. Every blog post should link up to a hub and sideways to 1–2 siblings. Every feature page should link to the closest doc and a CTA.

Use descriptive anchors (“Heist Score formula”) instead of “click here.” Anchors are context for crawlers and skimmers.

Product ↔ content loop

Feature pages should cite the blog posts that explain the why. Blog posts should deep-link to the exact UI or /how equivalent, not just the homepage. Docs should link to the live feature, not a 2022 changelog.

If you run a listing or directory surface (like /mine), link from educational posts to the action page in one hop. Education without a path is unfinished.

Keep crawl depth shallow

Important URLs should be reachable in 3 clicks from the homepage. Pagination, tag archives, and infinite filters should not be the only path to money pages.

Fix orphans: pages with zero internal inlinks. A quarterly crawl (Screaming Frog free tier, or a simple script) beats guessing.

Footer and nav hygiene

Nav is for destinations users need weekly. Footer is for legal and a few evergreen hubs — not fifty category spam links. Overstuffed footers look manipulative and dilute attention.

Update links when you rename routes. Broken internal links are free negative signals you inflicted on yourself.

Measure it

In analytics, watch paths from blog → signup. In GSC, watch which internal pages gain impressions after you add contextual links. Internal linking is one of the few SEO levers you fully control — use it weekly, not annually.
