The shift to AI-powered search represents the most significant transformation in digital discovery since Google's inception. When users query AI engines about your industry, products, or services, these systems synthesize information from thousands of sources to generate comprehensive answers– often without users clicking through to any website. This zero-click journey means your brand must be optimized for AI discovery or risk complete invisibility.
Your brand now faces three critical challenges:
Zero-Click Synthesis: AI engines (ChatGPT, Perplexity, Gemini) process billions of daily queries, delivering complete answers without website visits. Even ranking #1 on Google no longer guarantees visibility.
Sentiment Prioritization: AI analyzes millions of data points (reviews, social media, forums) to determine recommendations. Negative signals can permanently exclude your brand from AI suggestions.
Competitive Positioning: Companies using Answer Engine Optimization (AEO) achieve more AI mentions than traditional SEO-only brands.

AI engines like ChatGPT, Perplexity, and Gemini now process billions of queries daily, fundamentally transforming how customers discover brands. HubSpot's free AEO Grader reveals exactly how these AI platforms perceive your offerings, providing strategic insights to enhance your Answer Engine Optimization (AEO) and capture valuable audiences before competitors do.

Brand sentiment determines whether AI systems recommend your products or suggest competitors instead. These platforms analyze millions of data points– including customer reviews, social media mentions, news articles, and forum discussions, to form opinions about your brand that directly impact your brand visibility. Use HubSpot’s AEO Grader to optimize for AI sentiment, achieving higher brand mentions and awareness compared to a traditional SEO-only approach.

AI visibility measures how prominently your brand appears when users query AI-powered search engines like ChatGPT, Perplexity, or Gemini about your industry, products, or services. Unlike traditional SEO where you optimize for Google rankings, AI visibility determines whether these AI systems mention, recommend, or cite your brand in their synthesized responses.
Why this matters: The majority of businesses are reporting that customers now use AI engines for product research, and these platforms often provide complete answers without users needing to click through to websites. This zero-click reality renders traditional traffic metrics obsolete, making AI visibility tools essential for understanding and capturing your true market reach in 2025.
HubSpot's AEO Grader uses advanced natural language processing to simulate customer queries across ChatGPT, Perplexity, and Gemini. The tool analyzes whether your brand appears in responses, evaluates the sentiment of those mentions (positive, neutral, or negative), measures your share of voice compared to competitors, and identifies which specific topics or queries trigger brand mentions. Results compile into a 0-100 visibility score with platform-specific breakdowns and actionable optimization recommendations tailored to your brand's current performance.
Yes, HubSpot's AEO Grader is 100% free with no hidden costs, usage limits, or required credit cards, unlike Otterly.AI which charges $189/month after a trial. You can run unlimited reports, track multiple brands, and access all features without any paid upgrade requirements.

Traditional SEO optimizes content to rank highly in search engine results pages (SERPs), focusing on keywords, backlinks, and technical factors. Answer Engine Optimization (AEO) optimizes content to be selected and cited by AI systems that synthesize information from multiple sources. AEO requires structuring content for passage-level retrieval, using semantic triples for clarity, creating modular content blocks that work standalone, and ensuring factual accuracy with verifiable data. While SEO drives clicks, AEO drives mentions and recommendations within AI-generated responses.
HubSpot's AEO Grader analyzes ChatGPT (GPT-4o), Perplexity, and Gemini because these three platforms control the vast majority of AI-powered queries globally. ChatGPT processes billions of daily queries and increasingly serves as a primary research tool. Perplexity specializes in real-time web synthesis and is preferred by researchers for its source transparency. Gemini integrates with Google's ecosystem and YouTube, influencing both search and video discovery. Analyzing all three provides comprehensive visibility across the AI landscape.
AEO Grader provides 15+ customized recommendations based on your analysis, including content structure improvements for passage-level retrieval, semantic triple implementation strategies, FAQ sections targeting AI query patterns, entity optimization for Knowledge Graph alignment, fact and statistic integration for citation worthiness, technical markup for AI comprehension, competitive differentiation opportunities, and platform-specific optimization tactics for each AI search engine.
No, answer engine optimization actually enhances traditional SEO when done correctly. The content improvements required for AI visibility– clear structure, comprehensive answers, factual accuracy, and semantic clarity– align with Google's E-E-A-T guidelines and helpful content standards. In fact, many pages optimized for AI engines see improved traditional rankings because both systems increasingly value authentic, well-structured, authoritative content.
