Google's Reasonable Surfer Patent (US8117183B1, filed 2004, granted 2012) established that not all links on a page pass equal PageRank. Instead, link equity passed through a link is proportional to the probability that a \"reasonable surfer\" would click it.
\nHigh-probability click → high PageRank pass-through\nLow-probability click → minimal PageRank pass-through
\nThis means link placement, anchor text quality, and link context determine PageRank transmission — not just whether a link exists.
\nGoogle's patent describes factors that affect a \"reasonable surfer's\" click probability:
\n| Link Position | Click Probability | PageRank Value |\n|--------------|-------------------|----------------|\n| Contextual in-body (first 1/3 of content) | Very high | Maximum |\n| Contextual in-body (mid or lower content) | High | High |\n| Contextual sidebar (related content) | Medium | Medium |\n| Navigation (main menu) | Medium (varies by relevance) | Medium |\n| Footer navigation (relevant) | Low-Medium | Low-Medium |\n| Footer site-wide links (generic) | Very low | Minimal |\n| Paid/sponsored disclosure | Near zero | Near zero (likely nofollowed) |
\nImplication: A single body link from a relevant page is worth more than ten footer links.
\nAnchor text that matches the user's intent increases click probability. The Reasonable Surfer model factors anchor text into PageRank transmission:
\nHigh probability anchor text:
\nLow probability anchor text:
\nStep 1: Map the link graph.
\nUse LibreCrawl or Screaming Frog to export all internal links with:
\nStep 2: Score money pages by inbound link quality.
\nFor each priority page (service pages, location pages, booking/contact):
\nStep 3: Identify equity distribution problems.
\nCommon patterns detected:
\n| Problem | Symptom | Fix |\n|---------|---------|-----|\n| Homepage monopoly | 80%+ of links point only to homepage | Redistribute links from existing content to service/location pages |\n| Orphaned pages | Money pages have zero in-body links | Add contextual body links from related content |\n| Navigation-only equity | Key pages only get menu links, no body links | Add in-body mentions + links in related content |\n| Generic anchor flood | Majority of anchors are \"click here\" | Rewrite anchor text to descriptive phrases |\n| Deep link isolation | Priority pages buried 4+ clicks from homepage | Reduce click depth, add homepage or pillar page links |
\nStep 4: Identify link depth violations.
\nAll priority pages should be reachable within 3 clicks from the homepage. Pages at 4+ clicks depth receive significantly reduced crawl frequency and PageRank:
\nPages at 4+ clicks: add shortcut links from homepage or primary navigation.
\nPattern 1: Blog-to-money-page flow
\nBlog posts often rank well (high topical trust) but don't link to commercial pages. Add 1-2 contextual body links from each blog post to the most relevant service page.
\nPattern 2: Location page cross-linking
\nLocation pages should link to each other via a \"Service Areas\" section — but use relevant anchor text, not just city names. \"Tampa roof replacement\" links to Tampa page; \"St. Pete roofing contractor\" links to St. Pete page.
\nPattern 3: FAQ-to-service links
\nFAQ answers frequently answer questions that lead naturally to a service page. Every FAQ answer that mentions a service should include an in-context link to that service page.
\nOutbound links to non-authoritative sites: Every external link passes PageRank out of the site. Use rel=\"nofollow\" on external links to general sites. Do NOT nofollow links to government agencies, certifying bodies, or authoritative industry sources — those contextual links provide E-E-A-T signals that outweigh the PageRank cost.
nofollow overuse on internal links: Some WordPress themes add nofollow to category archive links, pagination links, or author archive links. Verify no internal links carry nofollow unless intentionally sculpting PageRank to noindex sections.
Redirect chains: Each redirect in a chain reduces PageRank transmission by approximately 10-15%. A 3-hop redirect chain loses 30-45% of the equity that would pass through a direct link. Audit and fix redirect chains to single hops.
\nAfter link equity redistribution, track:
\nTimeline: link equity changes typically reflect in ranking within 4-8 weeks (crawl cycle dependent).
