Internal link graph concentrates PageRank on low-value pages (Link analysis)

Google confirms PageRank and other link analysis systems remain part of its core ranking systems and that links signal relevance. Internal links are the part of that graph a site fully controls. This check models a proxy, internal link flow only, not Google's actual PageRank.

Reduce sitewide links to utility pages or move them out of primary navigation, add contextual links from well linked pages to priority pages, remove crawlable links to infinite filter and tag URLs, and link priority pages from the homepage or hub pages.

1. Crawl the site with a crawler that reports internal link scores (for example Screaming Frog Link Score or Sitebulb Page Rank), limited to indexable HTML URLs.
2. Export URLs sorted by internal link score and tag each as priority, supporting or utility.
3. Flag the issue when utility URLs occupy a large share of the top 20 scores or when priority URLs sit in the bottom half.
4. Inspect where the links to top scoring utility pages come from (header, footer, faceted navigation) to find the cause.

Written for the Link analysis systems and PageRank page (evidence: Confirmed). Google has not documented this system in a way a site can test directly, so this check measures a proxy for it, not the system itself.

Indirect. Better internal link flow can help priority pages get crawled and weighted more. Estimate only: size of any ranking change is not predictable from the model.

Google's ranking systems guide confirms link analysis systems and PageRank; Google's link best practices confirm links are a relevance and discovery signal; the Brin and Page paper describes how weight flows through links.
