Internal Linking
Internal linking connects your own pages to spread authority and aid discovery. Learn how to structure it and why orphan pages never get cited.
TL;DR
Internal linking is the practice of connecting pages within your own site. Every link tells engines two things: that the destination page exists and is worth reaching, and something about what it covers, communicated through the anchor text. It is the only major ranking and discovery factor entirely under your control.
Why internal linking matters
Crawlers move through your site by following links, so your link graph decides what gets discovered, how often it gets revisited, and how important it appears.
- Discovery: A page nothing links to is a page crawlers may never find, regardless of what your sitemap says.
- Authority distribution: Link equity from your strongest pages flows through internal links to the pages you point at.
- Topical context: Anchor text and surrounding copy tell engines what the destination is about.
- Citation support: Deep pages get cited in AI answers, and internal links are how those pages accumulate enough standing to be candidates.
How to structure internal linking
Audit for orphans first
Crawl your site and list pages with no incoming internal links. Those are invisible to link-following crawlers.
Link from strength to need
Your highest-authority pages should point at the pages you want to lift, rather than all linking to each other.
Keep important pages shallow
Anything reachable in three clicks from the homepage reads as important. Five clicks deep reads as forgettable.
Use descriptive anchor text
The anchor should describe the destination. Read more and click here describe nothing.
Link contextually, not just in navigation
Links inside body copy carry more weight than repeated sitewide footer links.
Build topic clusters
Related pages linking to each other and to a central pillar signal a coherent subject area rather than scattered posts.
Internal linking vs. backlinks
Internal linking: Links between your own pages. Fully under your control, immediately adjustable, and the primary way authority moves around your site.
Backlinks: Links from other domains. Largely outside your control, slower to earn, and the primary way authority enters your site at all.
Backlinks determine how much authority you have. Internal links determine where it goes. A site with strong backlinks and poor internal structure concentrates everything on a homepage nobody needs.
Internal structure decides which of your pages engines consider substantial enough to cite. Findrix runs a 31-point technical audit and ranks the sources feeding AI answers in your market, so you can see which of your pages get cited and which competitor pages fill the gap. Every gap comes with the fix already written: technical, content and off-site. The audit is free, takes about a minute, and requires no signup.
Internal linking metrics worth tracking
- Orphan page count: Pages with zero internal links pointing at them.
- Click depth: How many clicks from the homepage each important page sits.
- Inlink distribution: Which pages receive the most internal links, and whether those are the pages you care about.
- Anchor text variety: Whether destinations are described consistently without every link using identical wording.
- Contextual ratio: The share of links appearing in body content rather than navigation and footers.
Why most internal linking advice underdelivers
The standard guidance is to add more internal links, which teams follow by dropping a related posts widget at the bottom of every page. The links exist, the metric improves, and almost nothing changes.
What actually moves things is directional. A specific high-authority page linking to a specific page that needs help, with anchor text describing what the destination covers, does more than fifty automated links distributed evenly.
Most sites have a few pages absorbing the majority of internal links for historical reasons nobody remembers. Finding that imbalance takes an afternoon.
Frequently asked questions
How many internal links should a page have?
There is no correct number. Link where it genuinely helps a reader, which on a substantial page tends to mean somewhere between three and ten contextual links. Pages stuffed with links dilute the signal each one carries.
Do internal links pass link equity?
Yes. Authority earned from external links flows through your internal link graph, which is why the structure determines whether it reaches the pages that need it or pools on pages that do not.
What is an orphan page?
A page with no internal links pointing at it. Crawlers that navigate by following links may never find it, and engines reasonably infer that a page nothing on your site links to is not important.
