An AEO score is a numerical rating from 0 to 100 that measures how well your website is optimized for AI answer engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews. It evaluates three weighted categories - Technical (40%), Content (35%), and Authority (25%) - across 29 individual checks to determine how likely AI platforms are to find, understand, and cite your content. As Gartner reports, 37% of consumers now start searches with AI, including surfaces like Google AI Overviews. Your AEO score tells you whether your site is ready for that shift.
- Score range: 0 to 100, with 90+ rated "Excellent" for AI search readiness
- Three categories: Technical (40%), Content (35%), and Authority (25%)
- 29 individual checks: from robots.txt and schema markup to FAQ structure and content freshness
- Pages with FAQPage schema are associated with higher Gemini citation rates (third-party research; not required per Google)
- Free to check: Run a Quick Audit on any URL in under 60 seconds, no signup required
What Is an AEO Score?
An AEO score measures how well your website is structured for AI-powered search engines to find, understand, and cite your content. Think of it as a health check for AI visibility. Just as an SEO audit evaluates your readiness for Google, an AEO audit evaluates your readiness for ChatGPT, Perplexity, Gemini, Google AI Overviews, and other AI answer engines.
The score breaks into three categories that reflect how AI platforms actually process your website. First, they need to be able to access it (Technical). Then, they need to extract useful answers from it (Content). Finally, they need to trust that your content is credible enough to cite (Authority). A weakness in any single category can limit your AI visibility regardless of how strong the other two are.
For a complete understanding of the discipline behind AEO scoring, see our guide on what AEO is and how it works.
How Is an AEO Score Calculated?
An AEO score is calculated by running your website through 29 automated checks across three weighted categories. Each check evaluates a specific aspect of your site's AI readiness and returns a pass, warning, or fail result. The weighted scores are combined into a single number from 0 to 100.
The category weights - Technical (40%), Content (35%), Authority (25%) - reflect research from Semrush, BrightEdge, and analysis of how ChatGPT, Perplexity, Gemini, and Claude select sources. Technical carries the highest weight because if AI crawlers cannot access your site, nothing else matters.
What Goes into the Technical Score?
The Technical score measures whether AI crawlers can physically access, read, and understand your website. It accounts for 40% of your total AEO score and includes 16 individual checks. If AI bots cannot reach your content, your Content and Authority scores become irrelevant. For a deeper look at which bots are visiting your site, see our guide on how to track AI bot activity.
The 16 technical checks
- Cloudflare AI-bot blocking. Since July 2025, Cloudflare blocks AI crawlers by default for new domains. Your site might pass every other check but be completely invisible because a firewall is intercepting requests before they reach your server. This is the most commonly missed issue.
- WAF / bot-overlay detection. A separate probe that fetches your homepage as several AI bot user agents to catch firewall or bot-management overlays beyond Cloudflare that silently challenge or block AI crawlers.
- Robots.txt - AI index crawlers allowed. Verifies the four index crawlers that power AI search are not blocked: OAI-SearchBot, Claude-SearchBot, PerplexityBot, and GoogleOther.
- Robots.txt - user-initiated fetches allowed. Verifies the three fetchers that fire when a user prompt triggers a live page read are not blocked: ChatGPT-User, Claude-User, and Perplexity-User.
- Robots.txt - training crawlers blocked. Checks whether the ten training crawlers (GPTBot, ClaudeBot, Google-Extended, CCBot, Meta-ExternalAgent, Bytespider, Applebot-Extended, Amazonbot, Cohere-ai, anthropic-ai) are blocked, so your content is not used for model training without driving traffic back.
- llms.txt validation. Checks that your llms.txt file exists AND has valid content - a heading, description, and structured links. An empty file that returns a 200 status code is not enough. According to ALLMO, only 10.13% of websites have one.
- Sitemap.xml. Confirms a sitemap exists so AI crawlers can discover all your pages.
- Schema markup (five checks). Separate checks for Organization, Person, FAQPage, and Article schema, plus an entity-graph check grading your Organization's sameAs depth to encyclopedic anchors like Wikidata and Wikipedia. Structured data helps AI platforms understand your content at a machine-readable level.
- Schema @id connectivity. Checks whether your JSON-LD entities are wired together with @id references into one connected graph, instead of floating as disconnected blocks.
- SSR completeness. Re-fetches your pages as an AI search bot to confirm your main content is present in the server-rendered HTML, not hidden behind client-side JavaScript that crawlers may not execute.
- Page speed. Flags slow load times that can cause timeouts during crawling.
- Meta description. Verifies the homepage has a descriptive meta tag that AI platforms use as a summary when deciding whether to crawl deeper.
If AI crawlers cannot access your site, your Content and Authority scores become irrelevant. Technical carries 40% of the total score because access is the prerequisite for everything else.
What Goes into the Content Score?
The Content score measures how well your pages are structured for AI extraction and citation. It accounts for 35% of your total AEO score. Even if AI crawlers can access your site perfectly, they need to find clear, extractable answers to include in their responses.
The 8 content checks
- FAQ sections with schema. Third-party research associates FAQPage schema with higher Gemini citation rates. FAQ content provides pre-formatted question-answer pairs that AI engines can extract directly (schema is not required for AI features, but it aids extraction).
- Direct-answer paragraphs. Concise 40-60 word paragraphs that directly answer the question implied by the heading. According to AirOps research, 44% of ChatGPT citations come from the first 30% of a page. Front-loading answers dramatically increases citation probability.
- Heading hierarchy. Exactly one H1 per page, H2 for sections, H3 for sub-sections. No skipping levels. AI platforms use heading structure to understand content organization.
- Content freshness. Pages not updated within 90 days lose AI citations at 3x the normal rate. LLMrefs found AI-surfaced URLs are 25.7% fresher than traditional search results.
- Question-format headings. Headings phrased as questions ("How does X work?") match the way users prompt AI platforms, increasing the chance your content gets retrieved and cited.
- Data attribution. According to Semrush, content with source attribution is cited at 4x the rate of unattributed claims. Statistics and claims that cite their sources signal credibility to AI engines.
- Content depth. Sufficient word count on the page (the homepage check uses a 300-word landing-page threshold) so AI platforms have enough extractable substance.
- Answer blocks. Concise answers (one to two sentences, under 50 words) immediately following each heading. AI models extract short, direct answers at much higher rates than long paragraphs.
What Goes into the Authority Score?
The Authority score measures how credible and trustworthy your website appears to AI platforms. It accounts for 25% of your total AEO score and includes 5 checks. Authority signals help AI platforms decide whether to cite your content over a competitor's when both provide similar answers.
- Brand description. A clear, concise explanation of who you are and what you do within the first 200 words of your homepage. AI engines need extractable facts, not vague taglines.
- About page. A dedicated page with founder credentials, company history, and expertise signals. This feeds directly into E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness).
- Social proof. Testimonials, case studies, client logos, and review ratings that validate your claims. Display them prominently on key pages.
- Blog section. An active blog with regular content demonstrates ongoing expertise in your domain.
- External links. Links to authoritative sources (industry reports, research papers, official documentation) signal well-researched content.
According to RevvGrowth, there is a 0.65 linear correlation between website authority and frequency of AI citations - the single strongest predictor of whether AI platforms will recommend you. But authority alone is not sufficient. The Semrush AI Visibility Study found that only 6-27% of the most-mentioned brands also rank as top cited sources. Being known is not the same as being trusted enough to cite. For the per-state diagnostic that maps where each brand is stuck and the matching fix path, see the mention-to-citation framework.
There is a 0.65 correlation between website authority and AI citation frequency. But only 6-27% of the most-mentioned brands become top cited sources. Authority matters, but structure and extractability matter too.
What Is a Good AEO Score?
An AEO score of 90 or above is rated "Excellent" and means your site is well-optimized for AI citation. Most websites score between 40 and 70 on their first audit. A score above 80 puts you ahead of the majority of competitors - according to Acquia, only 20% of businesses have even begun implementing AEO.
The difference between a 70 and a 90 often comes down to a handful of high-impact fixes: adding FAQPage schema, configuring robots.txt for AI crawlers, creating an llms.txt file, and ensuring content freshness. For the specific fixes prioritized by impact, see our guide on how to improve your AEO score step by step.

Why Does Your AEO Score Matter in 2026?
Your AEO score determines whether AI platforms cite your content or your competitor's. As AI search grows - Gartner reports 37% of consumers now start searches with AI - the businesses being cited by ChatGPT, Perplexity, and Gemini capture traffic that converts at 4.4x the rate of traditional organic, according to Semrush.
Unlike traditional SEO where established domain authority carries significant weight, AI citation is a newer playing field. According to Search Engine Land, 9 out of 10 ChatGPT-cited pages appear outside Google's top 20 organic results. This creates an opportunity for businesses that optimize specifically for AI search to compete with larger players who have not yet adapted. To understand how ChatGPT's citation algorithm specifically works, see our guide on how ChatGPT recommends businesses.
AI citations also change 40-60% monthly, making ongoing monitoring essential. Your AEO score is the diagnostic that tells you whether you are improving, declining, or being overtaken - and what specifically to fix. For tracking whether your AEO improvements are translating into real traffic, see our guide on tracking AI referral traffic.
AI-referred visitors convert at 4.4x the rate of traditional organic traffic. Only 20% of businesses have started AEO. Your score tells you whether you are capturing this opportunity or missing it.
AEO Score vs SEO Score: What's the Difference?
An SEO score measures how well your site ranks in Google. An AEO score measures how well AI platforms can cite your content as a direct answer. They are complementary but measure different discovery channels.
A site can have a high SEO score and a low AEO score if it relies heavily on backlinks but lacks FAQ schema, has no llms.txt file, or blocks AI crawlers in robots.txt. The good news is that many AEO improvements also help SEO - adding FAQ schema, improving heading structure, and increasing content depth benefit both channels.

Frequently Asked Questions
#What is an AEO score?
An AEO score is a numerical rating from 0 to 100 that measures how well your website is optimized for AI answer engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews. It evaluates three categories - Technical (can AI crawlers access your site?), Content (can AI extract clear answers?), and Authority (does AI trust your content?) - across 29 individual checks (16 Technical, 8 Content, 5 Authority).
#How is an AEO score different from an SEO score?
An SEO score measures how well your site ranks in Google search results. An AEO score measures how well AI platforms can extract and cite your content as a direct answer. According to Search Engine Land, 9 out of 10 ChatGPT-cited pages appear outside Google's top 20, confirming that the two use different signals. For a full comparison, see our guide on AEO vs SEO.
#What is a good AEO score?
A score of 90 or above is Excellent - your site is well-optimized for AI citation. Scores between 75-89 are Good with room for improvement. Between 50-74 means meaningful gaps are holding back your AI visibility. Below 50 indicates significant structural issues. Most websites score between 40-70 on their first audit.
#How often should I check my AEO score?
Run a quick audit after each round of optimization changes, then weekly once you move into ongoing monitoring. AI citations change 40-60% monthly, so weekly checks catch regressions early. Monthly deep audits provide page-level detail and track whether fixes are translating into improved visibility across platforms.
#Can I check my AEO score for free?
Yes. The AI-Advisors Quick Audit on the homepage scores any website across 29 checks in under 60 seconds with no signup required. It covers Technical, Content, and Authority categories and returns specific recommendations. Other free tools include HubSpot's AEO Grader and semai.ai's scoring engine. Free audits are sufficient for SMB and pilot use; mid-market and enterprise teams typically graduate to paid AEO platforms with multi-page audits, ongoing tracking, and recommendations workflows.
#What has the biggest impact on AEO score?
Three factors tend to have the most impact: FAQPage schema (third-party research associates it with higher Gemini citation rates, though Google notes schema is not required for AI features), AI crawler access (ensuring robots.txt allows search bots while blocking training bots), and content freshness (pages not updated in 90+ days lose citations at 3x the normal rate).
#Why can't I just use my SEO tools to measure AI readiness?
Traditional SEO tools like Ahrefs, Semrush, and Google Search Console measure rankings, backlinks, and organic traffic - they do not track AI citations, AI visibility scores, or whether AI platforms mention your brand. AEO requires specialized measurement because AI platforms use different signals than Google's ranking algorithm.
#How does an AEO score relate to actual AI visibility?
Your AEO score measures the inputs - how well your site is structured for AI. AI visibility measures the output - whether AI platforms actually cite you. A high AEO score increases your probability of being cited, but other factors like cross-source consensus, citation velocity, and competitor content also influence actual visibility.
