Link Building
Link Graph
A link graph is a versioned directed-graph representation in which declared web resources are nodes and observed hyperlinks from a source resource to a destination resource are edges.
What it means
A defensible graph states the crawl scope, observation time, canonicalisation rules, redirects, edge direction, duplicate handling, relationship attributes and failed fetches. It is a model of collected evidence, not a complete copy of the web or Google's private systems. Metrics derived from it inherit every omission and normalisation choice in the dataset.
Why it matters
The data contract makes graph comparisons reproducible and prevents analysts from treating missing links, redirected URLs or vendor-specific coverage as universal facts.
Example
A crawl snapshot models 18,400 canonical URLs as nodes and 126,000 crawlable links as directed edges, preserving source page, destination, anchor, `rel` values, discovery time and redirect resolution.
Common mistakes
Do not call one crawler's sample “the web graph,” merge redirects without a record, discard failed fetches silently, treat repeated template links as unique publisher votes, infer private intent from topology or promise rankings from one graph metric.
How AYSA handles this
Signals reviewed
crawl scope, source URL, destination URL, canonical, redirect, anchor, rel attribute, discovery time, fetch state
Problem AYSA can identify
AYSA can identify ambiguous scope, silent redirect merging, duplicate edge inflation, stale observations and AI summaries that present missing coverage as confirmed absence.
Recommendation prepared
The graph contract records inclusion rules, uncertainty and version provenance before any topology or risk analysis.
Approval preview
The user sees dataset scope, exclusions, canonicalisation, redirects, duplicate policy, failed fetches, derived fields and any AI-assisted interpretation.
Execution
AYSA can store and compare approved graph snapshots and prepare supported owned-site link corrections; it cannot reproduce a search engine's private graph.
Verification
A repeated crawl reports added, removed, redirected and unresolved edges against the prior version without rewriting historical observations.
Limits
Coverage is incomplete, graph metrics are dataset-dependent, and provenance or human review does not automatically certify AI Act compliance.

Quick answers
Frequently asked questions
Is an SEO tool's link graph the complete web graph?
No. It reflects that tool's crawl scope, timing, normalisation and storage choices.
Does a missing graph edge prove that no link exists?
No. The source may be uncrawled, blocked, changed, rendered differently or outside the declared dataset.
