Measure How AI Search Engines Represent Your Brand
AI search engines like ChatGPT, Perplexity, and Gemini have fundamentally changed how buyers research brands. When a prospect asks an answer engine "what's the best CRM software" or "is [Your Brand] trustworthy," they receive a synthesized response – often without clicking through to a single website. This is the zero-click funnel: answer engines act as the first and sometimes only touchpoint between your brand and a potential customer.
Measuring brand visibility in AI is now a prerequisite for any effective marketing strategy. Traditional SEO metrics like traffic and click-through rates don't reflect how answer engines represent your brand in generated responses. HubSpot's AI Search Grader is a brand visibility measurement tool built specifically for this environment. The tool evaluates your brand across five scored dimensions – sentiment, presence quality, brand recognition, share of voice, and market position – and generates a free search engine optimization report.
Don't let AI search engines define your brand narrative without your input. Use HubSpot's free AI Search Grader to get a free one-time check of how leading engines represent your business today. When you're ready to track how that changes over time, HubSpot AEO monitors your brand continuously across ChatGPT, Perplexity, and Gemini.
AI Search Analytics: What You Get in Your Brand Report
HubSpot's AI Search Grader evaluates your brand across five dimensions, each contributing to your overall score out of 100.
1. Sentiment Results (up to 40 points)
This free review sentiment checker's highest-weighted dimension assesses the overall tone answer engines use when characterizing your brand. Scoring covers three layers:
- General sentiment: The overall positive, negative, or neutral tone of AI descriptions
- Contextual sentiment: How sentiment varies across different topics and use cases (e.g., customer support vs. product innovation)
- Source-based sentiment: The credibility and reliability of sources influencing how AI represents your brand
Positive sentiment indicators include phrases like "praised for intuitive interface" or "recognized for strong customer support." Negative brand sentiment in AI may be attributed to limitations or customer frustrations that appear in AI's training data.
2. Presence Quality (up to 20 points)
The presence quality metric of this free HubSpot audit service measures three components:
- Mention depth: How substantively answer engines discuss your brand, beyond surface mentions
- Source quality: The authority of sources that have shaped AI's understanding of your brand
- Data richness: The variety and completeness of information available about your brand in AI training data
3. Brand Recognition (up to 20 points)
HubSpot's free AI visibility tool also contains a Brand Recognition metric, measuring how widely recognized your brand is across AI training data. A high recognition score means answer engines can discuss your brand with depth and specificity, not just acknowledge that it exists.
4. Share of Voice (up to 10 points)
HubSpot AI Search Grader Share of Voice metrics show where your brand ranks relative to competitors in AI-generated responses at the time of your analysis. Scoring includes your brand's estimated percentage of category voice plus a rank bonus. For ongoing share of voice tracking across ChatGPT, Perplexity, and Gemini, see HubSpot AEO.
5. Market Competition (up to 10 points)
Wondering how to research your competitors online for free? AI Search Grader's Market Competition metric classifies how answer engines position your brand competitively. Your score reflects two components:
- Category role: Leader, Challenger, or Niche Player
- Innovation perception: Innovator, Disruptor, or Traditionalist
A low Market Competition score typically means answer engines have insufficient or inconsistent signals about where your brand stands competitively. HubSpot's free AI search tool surfaces this gap so you know which competitive signals to strengthen.
