Internal Linking Strategy: A Practical Guide

Why internal linking is an authority allocation problem

Internal links are authority signals. When a page links to another, it passes a fraction of its PageRank — the weight Google assigns based on the quantity and quality of external links pointing to that page. This means your internal link decisions determine how authority is distributed across your site. High-traffic, high-authority pages that link generously to their siblings and to your conversion pages concentrate ranking power where you need it. Pages that link to nothing, or that only link to the homepage, leave that authority stranded.

The practical implication: your most-linked internal pages should be the pages you most need to rank. For a B2B SaaS product, that usually means: the primary category pillar (e.g., 'what is an AI marketing team'), the core feature pages (e.g., '/content-agent', '/seo-agent'), and the comparison pages targeting high-intent buyers ('/compare/product-vs-competitor'). Every other page on the site should link to at least one of these when contextually relevant.

Most sites have the inverse problem: the homepage and blog index are heavily linked internally, but feature and comparison pages receive almost no internal links because they are not naturally referenced in blog content. Fixing this is a deliberate editorial decision, not something that happens automatically. It requires planning which pages are 'link targets' before the content that will link to them is written.

Building the internal link map before you publish

The most common internal linking mistake is treating it as a post-publication task. After a piece is published, nobody goes back to add links. The correct sequence is to plan the link map during the content calendar and brief stages — before any drafting begins.

For each new piece of content you schedule, answer three questions at the brief stage. First, which two to four existing pages should link TO this new piece? (The new piece needs incoming links the moment it publishes — not six months later.) Second, which two to four pages should this new piece link OUT to? (These are the pages you most need to rank, or the next logical step in the reader's journey.) Third, which of the new piece's topics are already covered in existing content that you can link to for depth?

Build a simple link map in your content calendar tool. For each URL, maintain two fields: 'will link to' (pages this URL will link out to) and 'linked from' (existing pages that should add a link to this URL when it publishes). When a new page publishes, the 'linked from' list tells you exactly which existing pages to update. This eliminates the orphan page problem — a page with no incoming links that Google may not discover or rank even if the content is strong.

Anchor text: specific, descriptive, and not the page title

Anchor text — the visible, clickable words in a link — is a direct relevance signal to Google. When another page on your site links to your comparison page using the anchor 'Hadrian vs. Jasper AI comparison', Google registers that as topical context for the destination page. When every link uses 'click here' or 'learn more', no topical signal is passed.

The anchor text guidelines are straightforward. Use descriptive, keyword-relevant anchor text that describes what the linked page is about. Vary the anchor text for repeated links to the same destination — do not use the exact same phrase every time. Avoid using the exact page title as anchor text in most cases; instead, use a phrase that is contextually natural in the linking sentence. Never use 'click here', 'this page', or 'here' as anchor text for internal links — these carry no topical signal.

A useful test: read the anchor text without seeing where it goes. If you can predict the topic of the destination page from the anchor text alone, it is descriptive enough. If not, revise it. This is especially important for comparison pages and feature pages, where precise anchor text accelerates ranking for commercial intent queries.

Auditing and maintaining your internal link structure

Internal link structure should be audited quarterly — the same cadence as keyword research. Three specific problems accumulate over time and each has a specific fix.

Orphan pages are URLs with zero incoming internal links. Google discovers them only through the sitemap — not through normal crawl — which means they receive no internal authority and often rank poorly even for good content. To find orphan pages, export your sitemap URLs and your Ahrefs / Screaming Frog internal-links report, then identify any sitemap URLs with zero internal links pointing to them. Fix: add each to at least two relevant existing pages using the link map process described above.

Broken internal links occur when pages are moved, slugs are changed, or content is deleted without updating the pages that link to them. A broken internal link wastes the authority that would have been passed and creates a poor user experience. Crawl your site with Screaming Frog or a similar tool quarterly; it will surface all 404 pages with their referring URLs. Fix broken links within 48 hours of discovery — the referring page's authority is being wasted until the link is corrected.

Link depth problems occur when important pages require more than three clicks to reach from the homepage. Pages buried deep in click depth receive less crawl attention and tend to rank lower. To diagnose, run a crawl and filter by 'click depth > 3'. For any high-priority URL (feature pages, comparison pages, high-converting landing pages) at depth 4 or greater, add a direct link from a page at depth 1 or 2 — often the homepage, a main navigation category, or a high-authority blog post. For teams running continuous SEO monitoring, this audit can be automated: an agent configured to flag new orphan pages or broken links at crawl time closes the gap that would otherwise require quarterly manual review.
