HubSpot AEO Grader: What the Free Score Tells You — and What It Doesn't

HubSpot AEO Grader: What the Free Score Tells You — and What It Doesn't

HubSpot's AEO Grader is free, takes about five minutes, and gives you a score for how AI answer engines perceive your brand. That combination makes it the most-run AI visibility tool on the internet by a wide margin. It is also the most misread. This guide explains exactly what the grade measures, what it structurally cannot measure, and what to do next depending on the number you got.

Last reviewed: August 2026.

What the AEO Grader actually does

You enter a brand and a domain. The tool runs dozens of test queries across ChatGPT, Perplexity, and Google Gemini, analyses the responses, and produces a report covering brand perception: sentiment, recognition, share of voice, source quality, and market positioning. The run takes three to five minutes.

It is genuinely free — no card, no usage cap, no features behind a paywall. That is unusual enough to state plainly, and it is not a trap: HubSpot is buying awareness at the top of a funnel, which is a fair trade for a five-minute report.

One naming distinction to avoid confusion: the free AEO Grader is not the same product as HubSpot AEO, the paid continuous monitoring tool launched in April 2026 at around €49 per month.

What the score measures — and what it doesn't

The grade is a snapshot of brand perception: how three models talked about you, on one day, in response to one set of prompts you did not choose. That is a real measurement. It is also a narrow one, and the gap between what people think it means and what it means is where the mistakes happen.

The Grader measures	The Grader does not measure
Sentiment and recognition across three engines	Google AI Overviews, Copilot, Claude, Meta
Share of voice against the field	Share of voice against a named competitor you care about
Source quality feeding the answers	Whether AI crawlers can reach your site at all
Positioning on the day of the run	Stability — the same run tomorrow may differ
Results for HubSpot's prompt set	Results for the questions your buyers actually ask

Three of those omissions matter more than the rest:

1. Engine coverage. Google AI Overviews are absent, and they reach more people than any standalone assistant because they appear inside ordinary search results. A brand can score well on three chat interfaces and be invisible where most of its audience actually is.
2. Prompt authorship. You do not choose the queries. A good score on generic category prompts says little about the specific question that precedes a purchase in your market.
3. Single point in time. AI answers are non-deterministic. One run is one sample. Drawing a trend from it is not possible, and drawing a strategy from it is worse.

What to do with your score

If you scored well

Do not conclude you are done. A strong perception score with weak technical foundations is common and unstable — it usually means models are describing you from third-party sources rather than your own site. Check whether AI crawlers can reach your pages and whether your content contains passages worth quoting. If the answer to either is no, your score depends entirely on other people continuing to write about you accurately.

If you scored poorly

Resist the urge to buy monitoring. A low grade tells you there is a problem; it does not tell you which of four possible problems it is:

• Access — AI crawlers blocked by robots.txt, a firewall, or bot protection. The most common cause and the cheapest fix.
• Structure — no passage on your pages that a model can lift as an answer.
• Entity — contradictory company facts across your site, directories, and profiles, so no model can place you confidently.
• Sources — the answers in your category are built from portals and publications where you do not appear.

Diagnose which one applies before spending anything. Subscribing to a monitoring platform at this stage buys you a monthly confirmation of a problem you already know you have.

If the report contained something factually wrong

Treat that as the highest-priority finding in the whole report. A model confidently misstating your pricing, ownership, or product scope does more damage than an absent mention, and the fix is always the same: find the contradiction in the evidence and remove it. Outdated pricing pages, directory entries from a previous rebrand, a subsidiary described as the parent company — that is where hallucinations come from.

Free alternatives and what they add

• GEO Score — our own free tool, and it answers a different question deliberately. Where the AEO Grader measures how models talk about you, the GEO Score measures whether your site is technically capable of being cited: crawler access, answer-shaped passages, structured data, entity consistency. If the Grader gave you a number you did not like, this is the diagnostic that tells you which of the four causes above applies. Running both takes ten minutes and costs nothing.
• Manual spot check — ask your ten most important buyer questions in ChatGPT, Perplexity, and Google yourself, and note which sources get cited. Twenty minutes, no tool, and it produces the one thing the Grader cannot: results for your prompts.

Paid tools, if you get there

Only once the foundations are sound does continuous monitoring earn its cost:

• Otterly.ai — from $29, four engines including AI Overviews. The natural next step after a free grade. See the review.
• Peec AI — from about €85, EU vendor, strong source attribution. See the review.
• Scrunch AI — $250+, seven engines and crawler analytics. See the review.
• AthenaHQ — from about $270, hallucination detection and prescriptive fixes. See the review.
• Profound — $399+, Prompt Volumes and Agent Analytics. See the review.

Frequently asked questions

Is the HubSpot AEO Grader really free?

Yes — no credit card, no usage limits, nothing locked behind a paid plan. It is a lead-generation tool, which is a reasonable trade for a five-minute report.

Which engines does the AEO Grader check?

ChatGPT, Perplexity, and Google Gemini. Google AI Overviews and Microsoft Copilot are not included.

Is the AEO Grader the same as HubSpot AEO?

No. The Grader is a free one-time assessment. HubSpot AEO is a paid continuous monitoring product launched in April 2026 at around €49 per month.

How accurate is the score?

It accurately reflects one prompt set, run against three engines, on one day. It is a valid snapshot and an invalid trend line.

What should I run after the AEO Grader?

A technical citability check. The Grader tells you how models describe you; it does not tell you whether they can read your site. The GEO Score covers that side and is also free.

Verdict

The HubSpot AEO Grader is a good free tool being asked to do a job it was never built for. As a five-minute read on brand perception across three chat engines, it is genuinely useful. As a basis for strategy it fails on three counts: it omits the highest-reach surface, it uses prompts you did not choose, and it samples a single moment of a non-deterministic system. Run it, read it, and then find out whether your site can actually be cited — that is the number that determines everything the Grader measures.
