An effective audit combines a crawl-based internal link model (an internal PageRank-style approximation, or at minimum a simplified internal link-count and click-depth analysis) with actual external backlink authority data to find where a site’s incoming authority currently concentrates, typically the homepage and a small number of top content pages, and then compares that concentration against how few authoritative internal links the site’s genuinely important revenue pages currently receive relative to their commercial importance. The highest-impact changes prioritize new internal links specifically from the highest-internal-authority pages toward those under-linked revenue pages, rather than broad, undirected internal-linking changes applied evenly across the site.
Step one: map where authority currently concentrates
The audit starts by identifying which pages on the site currently hold the most internal link authority, using a crawl of the site’s actual internal link graph combined with either a third-party tool’s internal-link-scoring model or a simplified proxy such as raw internal inbound link count and click depth from the homepage. This step, done well, usually reveals a pattern common to most sites: authority concentrates heavily on the homepage, main navigation-linked category pages, and whatever content has organically accumulated the most internal links over time (often older, well-established pages, or pages that happen to sit near the top of the site’s link hierarchy), while pages added later, or pages positioned deeper in the hierarchy, hold comparatively little internal authority regardless of their actual commercial importance.
Cross-referencing this internal picture against actual external backlink data for the same pages matters because internal link count alone doesn’t capture the full authority picture: a page might have relatively few internal links but substantial external backlink authority, or vice versa. The audit needs both views to accurately identify which pages are genuinely authority-rich (from either source) and which are authority-poor, rather than relying on internal link count alone as an incomplete proxy.
Step two: identify underperforming revenue pages and their current internal authority
In parallel, the audit identifies the site’s actual commercially important pages, the ones the business needs to rank well because they drive revenue, and measures how much internal link authority each currently receives relative to how commercially important it is. This is fundamentally a gap analysis: cross-referencing a list of revenue-priority pages (informed by business input, not just traffic data, since a page can be commercially critical while receiving comparatively little current traffic precisely because it’s underperforming) against where each of those pages sits in the internal authority map built in step one.
The output of this step should be a ranked list of revenue pages by the size of the gap between their commercial importance and their current internal authority level, since the pages with the largest gap, high commercial importance, low current internal authority, represent the highest-value targets for a linking intervention.
Step three: prioritize new links from the highest-authority pages to the highest-gap pages
Rather than making broad internal linking changes across the site (adding generic “related pages” modules everywhere, or increasing overall link density without direction), the highest-impact intervention specifically routes new internal links from the pages identified in step one as holding the most authority toward the specific pages identified in step two as having the largest authority gap relative to their commercial importance. This is the step that converts the audit’s diagnostic findings into an actual action plan: a small number of deliberate, high-authority-source-to-high-need-destination links, rather than an undirected general increase in linking.
This targeted approach matters because internal link equity, like external link equity, isn’t distributed independent of which pages point to which; a new internal link from a high-authority hub page contributes meaningfully more authority to its destination than the same link placed on a low-authority, rarely-linked page would. Prioritizing the source pages for new links, not just the destination pages, is part of what makes this strategy higher-impact than simply adding more links anywhere convenient.
An honest caveat about internal PageRank tools
Third-party tools that offer an “internal PageRank” or similar internal link-authority score are approximations built on their own crawl and their own modeling assumptions; they are not Google’s actual internal computation, and no external tool has access to that. These tools are useful directional aids for identifying relative authority concentration within a site’s own link graph, but their absolute scores shouldn’t be treated as precisely matching how Google’s systems actually weigh the same internal links. Treat the output as a reasonable relative ranking (this page likely holds more internal authority than that one) rather than a precise, Google-validated score.
Practical implication
Run the internal link crawl and authority mapping (via a crawler with internal link scoring, or a simplified click-depth and inbound-internal-link-count proxy if a dedicated tool isn’t available) alongside a backlink-authority pull for the same URL set, identify the revenue pages with the largest gap between commercial importance and current internal authority, and add a targeted, limited set of new internal links from the site’s highest-authority pages specifically to those identified gap pages. Re-crawl and re-assess after implementation to confirm the intended pages show measurable internal authority improvement before assuming the change achieved its goal, since internal link audits of this kind benefit from iterative verification rather than a single one-time pass.
