Internal LinkingLab.
Crawl a domain as a link graph. Measure how pages connect, how deep they sit, which URLs receive no internal references, where anchors repeat across competing targets, and where broken links, redirects or nofollow conflicts contaminate the architecture.
Internal linking is architecture.Measure the graph, not just the link count.
The crawl records sitewide link counts, page-level click depth, inbound references, orphan signals, redirect contamination, broken links and relation conflicts. TAO then applies explicit graph diagnostics to those observations.
Which pages become hubs?Which pages disappear at the edge?
The graph surfaces pages with high inbound counts, deep pages, orphan evidence and URLs involved in redirect or relation issues. It is a TAO visualization built from the declared crawl — not a Google PageRank calculation.
Every URL has a position in the graph.Depth, inbound links and outgoing links make it visible.
Each page record preserves click depth, internal and external outlinks, inbound references, orphan status, relation conflicts and links pointing to redirects.
| # | URL | DEPTH | INBOUND | OUTBOUND INTERNAL | ORPHAN | LINK CONFLICT | LINKS TO REDIRECTS | STATUS |

Anchor text connects meaning to destinations.Repeated text can reveal structural collisions.
Each internal link edge retains its source page, target page, anchor text, follow state, broken state and relation-conflict flag. TAO Anchor Collision groups normalized anchors and flags cases where identical text points to multiple internal targets.

Observed signals become diagnostics.The formula stays explicit.
These labels are TAO analytical constructs. They organize internal-linking problems but are not Google metrics, ranking factors or hidden PageRank values.
Requires a sitemap-aware crawl so discovered URLs can be compared with internal link edges. A cluster of such pages can indicate a disconnected publishing path.
TAO DIAGNOSTIC / SOURCE: PAGESTAO flags the count and ratio of crawled HTML pages at click depth 4 or deeper. Threshold is analytical, not a search-engine rule.
TAO DIAGNOSTIC / SOURCE: CLICK DEPTHComputed from internal anchor links. It identifies ambiguous internal naming patterns without claiming keyword cannibalization by itself.
TAO DIAGNOSTIC / SOURCE: LINKSTAO compares internal_links_count with inbound_links_count to surface candidate structural hubs that are themselves poorly referenced.
TAO DIAGNOSTIC / SOURCE: PAGESUses pages that link to redirects plus explicit Redirect Chains results, preserving the difference between one-hop redirects and chains.
TAO DIAGNOSTIC / SOURCE: PAGES + REDIRECT CHAINSThe diagnostic compares relation states at link and page level, then surfaces the affected destinations and their architecture footprint.
OBSERVED CHECK / SOURCE: LINK EDGESOne bounded crawl.Six architecture evidence layers.
The crawl produces a time-bounded structural snapshot. Site state, page records, link edges, redirects and indexability remain separate layers until TAO assembles the internal-link graph.
DOMAIN → LIMITS → DISCOVERY RULESDeclare the target, crawl ceiling, sitemap treatment and discovery boundaries required for a comparable snapshot.
CRAWL → PROGRESS → SITEWIDE COUNTSRecord crawl completion and aggregate counts for pages, internal links, broken targets, orphan signals and redirect references.
URL → DEPTH + INBOUND + OUTBOUNDPreserve page-level depth, link counts, canonical state and structural checks for every crawled URL.
SOURCE URL → ANCHOR → TARGET URLModel each internal connection with direction, anchor, follow state, target state and relation consistency.
SOURCE → HOPS → FINAL TARGETSeparate direct redirects, multi-hop chains and loops so their effect on internal navigation remains explicit.
LINKED URL → INDEX SIGNALS → PAGE STATERecord whether structurally present URLs are excluded through robots directives, response headers or page-level metadata.
Internal-link architecture is observable. “Link equity” is not directly measured here.
Click depth, inbound counts, internal edges, orphan signals, anchor text, broken targets and redirect states are crawl observations. TAO diagnostics organize them into architecture failure modes, but they are not Google PageRank values, ranking factors or hidden search-engine scores.
