Can supporting entities strengthen a canonical organization?

Motivation

Entity SEO practice often asserts that surrounding entities reinforce a canonical node. Public, falsifiable tests of that claim in AI Search contexts are scarce.

Facts

• George Barbu is founder of InfoWebPlus (stated on barbu.es/about and barbu.es/llms.txt).
• barbu.es is the Person Knowledge Platform; InfoWebPlus is the Organization (infowebplus.com). The roles are kept separate on purpose. Relationship vocabulary: founder, sameAs.
• Client websites are independent properties; inclusion requires explicit, legitimate attribution.

Assumptions

• AI systems form organization “hubs” partly from co-occurrence and link/ entity adjacency - not solely from a single homepage.
• Supporting entities help when they are consistent and non-spammy.

Unknowns

• Whether client-site mentions help or dilute the hub.
• Whether person-first vs organization-first probing changes outcomes.

Hypothesis

H₀: Strengthening cross-links and consistent naming across the chain does not improve hub recognition metrics for InfoWebPlus relative to baseline.

H₁: After documented reinforcement of the George Barbu → barbu.es → InfoWebPlus → clients chain, AI systems more often (a) name InfoWebPlus as the organization hub and (b) correctly situate George Barbu and barbu.es relative to that hub.

---

Methodology

Design type

Graph reinforcement experiment: inventory current public edges → add only legitimate edges → re-probe hub questions.

No fabricated clients, fake bylines, or deceptive co-citations.

---

Environment

Dimension	Value
Primary domains	https://barbu.es/, https://infowebplus.com/, approved client attributions
Surfaces under test	https://barbu.es/about/, https://barbu.es/work/, partner/credit pages, schema @id links
AI systems probed	ChatGPT, Claude, Gemini, Perplexity
Measurement window	Baseline inventory + ≥ 45 days post reinforcement
Geographic / language scope	English (add locale variants only as amendments)
Tools used	Entity inventory sheet, link graph export, probe logs

Variables

Independent variables

• Density and clarity of truthful cross-links in the chain
• Presence of reciprocal, accurate attribution on client sites

Dependent variables

• Hub naming rate: probes that identify InfoWebPlus as the primary org
• Chain completeness score: fraction of chain nodes correctly related
• Misattribution rate: wrong parent company / wrong personal brand fusion

Controlled / held constant

• No paid placement networks
• No astroturfed directories beyond disclosed, legitimate listings

Confounds to monitor

• Concurrent schema deploy (Exp-002) and partner pages (Exp-004)
• Client sites changing design/removing credits
• Name collision on “Barbu” / brand strings

---

Procedure

1. Build an entity inventory: nodes, URLs, existing edges, evidence class (Fact / Assumption).
2. Baseline probes for hub and chain questions.
3. Implement only approved edge reinforcements (copy + schema + credits).
4. Log each change with URL, date, before/after screenshot or HTML hash.
5. Re-probe on cadence; score chain completeness.

Results

Status: Planned. No results claimed.

Metric	Baseline	Post-intervention	Notes
Hub naming rate	n/a	n/a	Not collected
Chain completeness score	n/a	n/a	Not collected
Misattribution rate	n/a	n/a	Not collected

Observations

• Pending inventory freeze.

---

Limitations

• Client cooperation limits graph completeness.
• Personal brand and company brand may remain entangled in training data.
• Causal attribution is weak if multiple lab experiments ship together.

---

Future Work

• Directed edge ablations (remove client tier vs remove barbu.es tier).
• Multilingual chain consistency.
• Wikidata / external KG reconciliation (separate ethics/review gate).

Replication Notes

Only use entities and clients that have consented to clear attribution. Publish the edge list alongside results so others can audit for spam patterns.
