What is Agent Engine Optimization (AEO)?
AEO is the practice of improving how AI systems, ChatGPT, Claude, Gemini, Perplexity, discover and recommend your brand. It's the SEO of the AI era. This guide explains what it is, why it matters, and how to measure it.
What is Agent Engine Optimization?
Agent Engine Optimization (AEO) is the practice of structuring your brand's online presence so that AI systems, including ChatGPT, Claude, Gemini, and Perplexity, can discover, understand, and recommend your brand when users ask relevant questions.
When someone asks an AI system “what's the best project management tool for remote teams?”, the AI doesn't run a Google search. It draws on its training data, real-time web retrieval, and structured entity knowledge to form an answer. Whether your brand appears in that answer, and how it's described, depends entirely on your AI visibility.
AEO is the discipline of measuring and improving that visibility. Your AI Visibility Score™, a composite 0–100 metric, tells you exactly where you stand across each platform and what to fix.
Why AI visibility matters
AI-powered discovery is reshaping how buyers find products and make decisions. Millions of daily queries, “which CRM should I use?”, “what's a good alternative to Salesforce?”, “best marketing tool for a B2B SaaS?”, are now answered directly by AI systems, not search engines.
The brands that appear in these answers capture attention at the highest-intent moment in the buyer journey, when someone is actively looking for a recommendation. The brands that don't appear are completely invisible to this growing channel.

AEO vs SEO: key differences
SEO and AEO are complementary, but they optimise for different systems. SEO optimises for Google's crawl and rank algorithm. AEO optimises for how AI models understand and surface your brand.
| ASPECT | SEO | AEO |
|---|---|---|
| Goal | Rank on Google search results | Be recommended by AI systems |
| Signal type | Backlinks, keywords, on-page | Entity presence, structured data, third-party mentions |
| Output | SERP ranking position | AI Visibility Score™ (0–100) |
| Tool | Ahrefs, SEMrush, GSC | BEACON AI |
| Measurement | Keyword rankings | Mention rate, rank position, sentiment across AI platforms |
The 5 AEO signals AI measures
BEACON AI scores your brand across 5 signals on each AI platform, aggregated into your AI Visibility Score™:
Does your brand appear at all when relevant category queries are run? This is the baseline, if you're not mentioned, everything else is moot.
When your brand is mentioned, where does it appear? First mention vs. mentioned third or fourth carries significant difference in click and recall.
How does the AI frame your brand, positively, neutrally, or negatively? Sentiment shapes whether a user acts on the recommendation.
Are you visible on all 4 platforms or just one? Brands often discover they score 78 on Perplexity and 12 on Google AI Overview, a gap competitors exploit.
AI answers are non-deterministic. BEACON runs multiple queries per platform to measure how consistently your brand appears, not just whether it appears once.
What is agent.json?
agent.json is a machine-readable brand identity file you deploy to your domain root (yoursite.com/agent.json). Think of it as robots.txt for AI systems, a structured, first-party signal that tells every AI platform who you are, what category you're in, your differentiators, pricing model, and ideal customer.
BEACON AI auto-generates an agent.json with every audit. Deploying it is one of the highest-leverage AEO actions a brand can take, it's a direct, authoritative signal that AI crawlers can read. Generate your agent.json →
