Verity Score vs HubSpot AEO Grader: Shopify GEO audit or free AI brand grade?

Verity Score fixes the source: 9 GEO factors, 22 anti-hallucination detectors, 8 AI Buyer Score dimensions, 15 benchmarked verticals, 100+ signals per audit. HubSpot AEO Grader is a free tool that grades a brand presence in AI answers across three engines. Both are free but measure different things: Verity audits your Shopify store source, HubSpot grades your brand perception.

perception then source

HubSpot gives a perception snapshot; Verity diagnoses the source to fix.

The short answer

HubSpot AEO Grader (formerly AI Search Grader) is a free, one-shot diagnostic: it queries three engines (ChatGPT, Perplexity, Gemini) with test queries and returns a score out of 100 across sentiment, presence, brand recognition, share of voice and market position. It takes a brand name, location and description as input; it grades brand perception, at the brand level, not the source of your site.

Verity Score is a free, no-email diagnostic of the Shopify source itself: schema.org, proof, reviews, prices, variants, policies, agent-card, sitemap and AI-referred handoff. It does not grade brand perception; it checks, at the product level, whether the store exposes the signals AI engines must read before they can recommend it.

How to decide between HubSpot AEO Grader and Verity Score

Both tools are free, but they do not measure the same thing. HubSpot grades brand perception in AI answers; Verity checks whether the Shopify source is readable and recommendable at the product level.

Brand-perception grade

HubSpot

HubSpot returns a score out of 100 (sentiment, presence, share of voice) at the brand level, which Verity does not.

Source diagnosis

Verity

Verity checks whether AI engines can read your schema, proof, policies and reviews at the product level, which HubSpot does not.

Product level

Verity

Verity audits the Shopify product source; HubSpot stays at the brand level.

Shopify action

Verity

Verity outputs concrete Shopify fixes; HubSpot outputs a grade and general brand recommendations.

Access

Verity

Both are free; Verity needs no email, HubSpot asks for an email for the full report.

Choose Verity Score when

  • You want a free, immediate read on whether AI agents can understand and recommend your Shopify store, at the product level.
  • You need a prioritized fix list for schema, proof, reviews, policies, variants and AI-referred handoff.
  • You want a source diagnostic without leaving an email.

Choose HubSpot AEO Grader when

  • You want a free snapshot of your brand perception in AI answers.
  • You want a score out of 100 (sentiment, presence, share of voice) across three engines.
  • You work at the brand level rather than at the Shopify product source level.

Use both when

Use HubSpot AEO Grader for a free brand-perception snapshot, then Verity Score to diagnose and fix the Shopify source that makes the store recommendable. HubSpot measures perception; Verity fixes the product source.

  2. 2 Run the free Verity Score audit on the Shopify store URL to diagnose the source at the product level.
  3. 3 Fix the source blockers: schema, proof, reviews, policies, variants and AI-referred handoff.
  4. 4 Re-audit the source with Verity after theme, app or catalog changes.

Limits of this comparison

  • Verity Score does not grade brand perception and does not track share of voice over time.
  • HubSpot AEO Grader is a one-shot diagnostic at the brand level; it does not audit the Shopify product source and does not track visibility continuously.
  • The free, no-account access and the three-engine coverage (ChatGPT, Perplexity, Gemini) come from the public HubSpot page in June 2026 and may change.

Frequently asked questions

Is the HubSpot AEO Grader a Shopify GEO tool?
No. The HubSpot AEO Grader is a free tool that grades a brand perception in AI answers across three engines, at the brand level. It is not a Shopify product source audit. Verity Score is built for the Shopify source: schema, proof, reviews, policies, variants and AI-referred handoff at the product level.
Are HubSpot AEO Grader and Verity Score both free?
Yes, both are free. The HubSpot AEO Grader asks for an email to show the full report; Verity Score asks for no email and no store connection. They measure different things: HubSpot grades brand perception, Verity audits the Shopify product source.
What does the HubSpot AEO Grader do that Verity Score does not?
The HubSpot AEO Grader returns a score out of 100 of brand perception (sentiment, presence, recognition, share of voice, position) at the brand level. Verity Score does not grade perception; it audits whether the Shopify source is readable, trustworthy and recommendable at the product level and produces a prioritized fix list.
Which AI engines does the HubSpot AEO Grader cover?
The HubSpot AEO Grader queries three engines: ChatGPT, Perplexity and Gemini. Verity Score audits whether the Shopify source exposes the signals AI engines need to read and recommend the store, rather than grading outputs engine by engine.
Should a Shopify brand use the HubSpot AEO Grader or Verity Score?
Both, in that order, since they are free and complementary. Use the HubSpot AEO Grader for a brand-perception snapshot, then Verity Score to diagnose and fix the Shopify product source that makes the store recommendable.
What is a GEO audit for Shopify?
A GEO audit checks whether a Shopify store can be read, understood, cited and recommended by AI engines such as ChatGPT, Perplexity, Claude and Google AI Mode. It reviews structured data, proof, policies, reviews, crawlability and AI discovery files.
How is a GEO audit different from a classic search audit?
A classic search audit focuses on pages, queries and rankings. A GEO audit focuses on whether the store can become a trusted source inside generated answers and agentic buying journeys.
Why do Shopify stores need a specific audit?
Shopify exposes useful signals, but themes, review apps, variants, Markets, scripts and JSON-LD often create gaps between what humans see and what AI agents can read. The audit needs Shopify-specific checks.
Which surfaces matter most for AI engines in 2026?
For citations, the priority is still canonical HTML, Product/Offer/AggregateRating schema, visible policies, readable reviews, the sitemap and internal links. For agent discovery, agent-card.json is currently consumed more than llms.txt/ai.txt in observed logs; it should expose identity, capabilities and canonical URLs without replacing source pages.
Is Product schema enough to be recommended by AI?
No. Product schema is a foundation, but AI systems also check visible proof, shipping and return policies, readable reviews, coherent prices, variants and clear product content.
Are JavaScript-loaded reviews visible to AI agents?
Often not. If stars and review counts only appear after JavaScript loads, some crawlers miss them. AggregateRating and review proof should be exposed in reliable HTML or JSON-LD.
What is the AI Buyer Score?
The AI Buyer Score simulates an AI buyer's decision across price, availability, trust, proof, shipping, returns, variants, specs and claim consistency. It also checks the AI-to-purchase handoff when it affects recommendation confidence: do the price, variant, promotion and policies cited by AI match what the AI-referred human visitor sees?
How long does it take to improve a GEO score?
Technical fixes can often be made in days. Recrawling varies by engine, but schema.org, agent-card.json, sitemap coverage, FAQ content and clear policies are usually the first signals to improve. llms.txt follows as a supporting index.
