What is the Claims & Proof pillar?
The third pillar of the Verity Score audit analyzes your store’s credibility in the eyes of AI systems. It detects your marketing claims (shipping promises, guarantees, quality labels) and verifies whether structured proofs support them.
Why it matters for AI
LLMs have a fundamental problem: hallucination. To counteract it, they’re trained to prefer sources that provide verifiable proofs. In practice, 96% of Google AI Overview citations come from sources with strong E-E-A-T signals (Wellows, 2026). The foundational research in the field confirms that adding authoritative citations boosts AI visibility by up to +115%, and that direct quotations bring an additional +28% visibility (Princeton GEO, KDD 2024).
When an LLM needs to recommend a product, it looks for:
- Structured data (schema.org) that confirms claims
- Accessible policy pages that detail conditions
- Coherence between what’s displayed and what’s read in the code
A store displaying “Free 24h shipping” without structured proof is treated as less reliable than a store with a detailed shipping policy and an Offer schema with shippingDetails. Brand mentions correlate at r=0.664 with AI citation probability (SurferSEO, 2025). Security is also part of this verification: Microsoft Security documented over 50 prompt injection attempts in February 2026 aimed at poisoning AI recommendations, which pushes engines to favor claims backed by structured data (Microsoft Security, 2026; OWASP LLM01:2025).
What AI actually checks
For each type of claim, AI agents look for a corresponding structured proof: policy pages for shipping/return promises, AggregateRating for review claims, Offer schema for pricing claims.
AI also verifies coherence between what’s displayed visually and what’s readable in the code. A “4.8/5” badge displayed as an image but absent from schema creates an inconsistency signal.
Verity Score automatically audits these aspects and tells you precisely where gaps exist between your claims and your proofs.
Finding Types
- Critical (red): Claim without any proof, numerical inconsistency, inaccessible proof
- High (orange): Partial proof, JS-only proof, ambiguous claim
- Positive (green): Proven claim, complete policy, confirmed coherence
How to Fix on Shopify
- Write clear, accessible policy pages (Settings → Policies)
- Add
shippingDetailsandhasMerchantReturnPolicyto your Product schema - Audit manually: for each displayed badge, verify the same value exists in JSON-LD
