What Is an AEO Checker?
An AEO checker is a specialized tool designed to evaluate how well your web pages are optimized for Answer Engine Optimization (AEO). Unlike traditional SEO tools that focus on keyword rankings and backlinks, an AEO checker analyzes technical and structural elements that determine whether AI-powered search engines like ChatGPT, Perplexity, and Google AI Overviews can effectively cite your content.
As AI search continues to reshape how users find information online, making your content "answer-engine ready" has become essential. Our free AEO checker provides a comprehensive 10-point analysis covering content structure, schema markup, technical accessibility, and AI citation readiness —giving you actionable insights to improve your answer engine visibility.
Simply enter any URL, and within seconds you'll receive a detailed report showing exactly where your page excels and where it needs improvement. No registration, no payment, no hassle.
How Does AEO Checker Work?
Our AEO checker uses a server-side analysis engine that fetches your page's HTML, parses its structure, and runs a comprehensive 10-point evaluation across four key categories. Here's exactly how the process works, with a real-world example at each step:
Enter a URL
Paste any webpage URL into the checker tool. Our server fetches the complete page HTML, including all metadata, schema markup, and content. For example, if you enter https://yourblog.com/best-running-shoes-2024, our system retrieves the full rendered HTML of that page for analysis.
Automatic Analysis
Our engine runs 10 checks across 4 categories: Content Structure (Q&A detection, headings, paragraph quality), Structured Data (schema presence, type, completeness), Technical Accessibility (viewport, page size), and AI Citation Readiness (dates, authorship). For our running-shoes example, it would detect whether the page has FAQ sections, Article schema, and author bylines.
Review Your Score
Get an AEO score out of 100 with a detailed breakdown. Each of the 10 factors shows a pass/fail status with specific explanations. For instance, the running-shoes page might score 70/100: passing on headings and page size but failing on missing FAQPage schema and lack of visible date indicators — with clear reasons for each result.
Fix & Improve
Follow the prioritized, actionable suggestions to improve your score. For the running-shoes page, the tool would recommend adding JSON-LD FAQPage schema to the existing Q&A section, inserting publication dates with time elements, and adding visible author attribution — each with concrete implementation guidance.
Why AEO Matters for Your Website
The rise of AI-powered search represents the biggest shift in how users find information since Google's founding. Today, over 50% of Google searches trigger AI Overviews, ChatGPT attracts over 800 million weekly active users, and Perplexity processes millions of AI-generated answers daily. If your content isn't optimized for AI answer engines, you're missing out on a massive and growing source of traffic.
Unlike traditional search results where users click through to websites, AI answer engines often cite and summarize content directly in the answer interface. This means your content needs to be structured in a way that makes it easy for AI to extract, understand, and cite correctly. Pages with clear Q&A structures, proper schema markup, and well-organized content are significantly more likely to be referenced by AI engines.
Answer engine optimizationisn't about gaming the system — it's about making your genuinely valuable content more accessible to both users and AI. By improving your AEO score, you're also making your content better for human readers. Clear headings, structured data, and well-written paragraphs benefit everyone.
10 AEO Check Factors Explained
Each factor below represents a critical dimension of answer engine readiness. Understanding what each check evaluates — and why it matters — helps you prioritize your optimization efforts effectively. The factors are organized into four categories: Content Structure (CS), Structured Data (SD), Technical Accessibility (TA), and AI Citation Readiness (AC).
CS-1: Q&A Structure Detection
Checks whether your page contains clear question-and-answer structures, such as FAQ sections, "How to" guides, or definition blocks. AI engines like ChatGPT and Perplexity heavily favor pages with explicit Q&A formatting because they can directly extract and cite these answer blocks in their responses. For example, a software company's documentation page with well-structured troubleshooting Q&A pairs is far more likely to be cited by AI than a dense wall of text. To optimize, use HTML5details/summary elements, dedicated FAQ headings, or schema-marked Q&A sections with at least 5-10 comprehensive pairs covering common user queries.
CS-2: H1 Heading Clarity
Evaluates whether your main heading (H1) clearly and concisely communicates the page's primary topic. A single, well-crafted H1 — ideally between 20 and 70 characters — helps AI engines instantly understand your content's focus and match it to relevant queries. For instance, a product review page with the H1 "Best Wireless Headphones 2024: In-Depth Comparison & Buyer's Guide" provides far more context than a generic H1 like "Products" or "Review." Avoid multiple H1 tags or vague headings; each page should have exactly one clear H1 that includes your primary keyword and signals the content type.
CS-3: Paragraph Extractability
Measures whether your content paragraphs are substantial enough to carry meaning when extracted and cited independently by AI engines. Paragraphs averaging 50+ characters tend to contain enough context to stand alone in an AI-generated answer. Short, fragmented paragraphs — like single-sentence marketing slogans or navigation text — are unlikely to be useful when extracted. For example, a health blog page about nutrition should structure its advice into well-formed, self-contained paragraphs rather than bullet-point fragments that lack context. This factor is especially important for informational content where AI engines may pull direct excerpts.
SD-1: Schema Markup Presence
Checks for the presence of JSON-LD structured data (schema.org markup) embedded in your page. Schema markup acts as a machine-readable layer that explicitly tells search engines and AI what your content represents — whether it's an article, FAQ, product, recipe, event, or organization. Pages with schema markup are significantly more likely to appear in AI-generated answers because the structured data eliminates ambiguity. For example, an e-commerce product page with Product schema (including price, availability, and reviews) gives AI engines everything they need to cite product details accurately. Without schema, AI must rely solely on natural language parsing, which is far less reliable.
SD-2: Schema Type Coverage
Verifies that the schema types declared on your page actually match the content type you're publishing. Mismatched schema types — such as using Article schema on a product page or FAQPage schema on a blog post without actual Q&A content — can confuse AI engines and reduce your content's credibility. Use FAQPage for FAQ sections, Article (or BlogPosting) for blog content, Product for e-commerce listings, Recipe for cooking content, and Organization or LocalBusiness for company information pages. A common scenario: a tech review blog should use Article schema with author and datePublished fields, not a generic WebPage schema that provides zero semantic context.
SD-3: Schema Field Completeness
Checks that the required and recommended fields within your schema markup are actually populated. A schema declaration with empty or missing fields is almost as useless as no schema at all. For Article schema, critical fields include headline, author (with name and url), datePublished, and dateModified. For FAQPage, each question must have both a name and acceptedAnswer text. Think of it this way: if you're a recipe website, having Recipe schema without cookTime, ingredients, or instructions is like giving AI a book with a title but no pages. Complete, well-populated schemas give AI engines the rich context they need to confidently cite your content.
TA-1: Viewport Meta Tag
Confirms your page includes a proper viewport meta tag (<meta name="viewport" content="width=device-width, initial-scale=1">), which is essential for mobile responsiveness. While this may seem purely technical, it's increasingly important for AEO because a large and growing share of AI search queries come from mobile devices. AI engines like Google's AI Overviews prioritize mobile-friendly pages in their citation sources. A page without a viewport tag — common on older websites — may render improperly on phones, leading to poor user experience and lower AI citation potential, regardless of content quality.
TA-2: Page Size Performance
Measures your HTML file size to ensure it falls within an acceptable range for fast loading and efficient crawling. Pages under 150KB load significantly faster on all devices and are more likely to be crawled completely by AI indexing bots. Oversized pages — often caused by inline styles, excessive embedded scripts, or bloated HTML — risk being truncated during crawl, meaning AI engines may miss critical content. For example, a news article page with 500KB of HTML (due to unoptimized inline SVGs and embedded tracking scripts) may have its actual article content cut off during AI processing. Aim for clean, lean HTML that prioritizes content over presentation markup.
AC-1: Date Visibility
Checks whether your content displays visible publication or last-updated dates, and whether those dates are machine-readable viatime elements with datetime attributes or through datePublished/dateModified in schema markup. Fresh, dated content is strongly preferred by AI engines for any time-sensitive query — from news and trends to product reviews and technical tutorials. A blog post from 2021 without a visible date might be treated as stale or unreliable by AI engines, even if the content is still accurate. Conversely, a regularly updated page with a clearly displayed "Last updated: June 2026" timestamp signals relevance and trustworthiness. This factor is one of the easiest to fix and one of the most impactful for AEO.
AC-2: Author Signals
Verifies that your content includes visible author attribution — such as author bylines, bio sections, or author pages — and ideally author information in your schema markup. Content with clear authorship signals is perceived as more credible and authoritative by AI engines because it aligns with Google's E-E-A-T framework (Experience, Expertise, Authoritativeness, Trustworthiness). For example, a medical advice article attributed to "Dr. Jane Smith, MD, Board-Certified Cardiologist" with linked credentials carries significantly more weight than an anonymous article on the same topic. Even for non-medical content, showing that a real person with relevant expertise authored the content increases the likelihood of AI citation. Include author name, a brief bio, and link to a detailed author page where possible.
How to Improve Your AEO Score
Improving your AEO scoredoesn't require a complete website overhaul. Start with the highest-priority fixes identified by our AEO checker and work your way down. Here are the most impactful improvements you can make:
- Add FAQ content: Create a dedicated FAQ section using clear question-and-answer formatting. Use HTML5 semantic elements like
details/summarytags. Aim for at least 5-10 comprehensive Q&A pairs targeting common user queries. - Implement JSON-LD Schema:Add structured data markup to your pages. Start with Organization schema, then add FAQPage for FAQs and Article schemas for blog content. Use Google's Rich Results Test to validate your markup.
- Optimize your H1:Ensure each page has exactly one clear, descriptive H1 heading between 20-70 characters that includes your primary keyword. Avoid generic headings like "Welcome" or "Home."
- Structure your paragraphs: Write substantive paragraphs (50+ characters) that are self-contained and understandable when extracted from the page context. Avoid single-sentence fragmented paragraphs.
- Add date indicators: Display publication dates using
timeelements with datetime attributes or includedatePublishedin your schema markup. - Show author attribution: Add visible author bylines and include author information in your schema markup. This builds E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) signals valued by both traditional search and AI answer engines.
AEO vs SEO — What's the Difference?
While SEO (Search Engine Optimization) has traditionally focused on optimizing for search engine ranking factors like keywords, backlinks, and page speed to appear in blue-link results, AEO (Answer Engine Optimization) takes a different approach. AEO optimizes content specifically for generative AI engines that provide direct answers rather than lists of links.
The key differences: SEO prioritizes ranking position and click-through rates, while AEO prioritizes content extractability and citation worthiness. SEO uses meta tags and keyword density; AEO uses structured data and clear Q&A formatting. SEO backlinks signal popularity; AEO author signals signal credibility.
The good news? AEO and SEO are complementary, not competing. Many AEO optimizations —like clear heading structure, quality content, and fast loading times—also improve your traditional SEO. Think of AEO as the next evolution of SEO, adapting your content strategy for the AI-first era of search while maintaining everything that already works.

How is AEO different from SEO?
Traditional SEO (Search Engine Optimization) focuses on ranking in search engine results pages — optimizing for keywords, backlinks, meta tags, and page speed to appear higher in blue-link results. AEO (Answer Engine Optimization), by contrast, optimizes content specifically for AI-powered answer engines like ChatGPT, Perplexity, and Google AI Overviews that provide direct, cited answers rather than lists of links. The key difference is the end goal: SEO aims for click-throughs to your website, while AEO aims to make your content the authoritative source that AI engines cite directly. The strategies are complementary — many AEO best practices like clear headings, structured data, and quality content also improve your traditional SEO rankings. Think of AEO as the natural evolution of SEO for the AI-first era of search.
What is a good AEO score?
Our AEO scoring uses a clear tiered system to help you gauge your page's answer engine readiness at a glance. A score of 80–100% is considered excellent — your page is well-optimized and highly likely to be cited by AI engines. 60–79% is good, meaning most fundamentals are in place but there are specific opportunities for improvement. 40–59% indicates your page needs work, with several critical factors requiring attention. Below 40% means significant optimization is necessary before AI engines will consider your content citation-worthy. We recommend aiming for 80% or above for optimal visibility across all major AI answer engines. Each percentage point represents one of the 10 factors, so a score of 70/100 means 7 checks passed and 3 need fixing.
How can I improve my AEO score?
Improving your AEO score starts with addressing the specific issues identified by our checker, working from highest to lowest priority. The most impactful improvements are: (1) Add structured FAQ content using semantic HTML and JSON-LD FAQPage schema — this directly enables AI engines to extract and cite your answers. (2) Implement proper schema markup for your content type (Article, Product, Recipe, etc.) with all required fields populated. (3) Optimize your H1 heading to be clear, descriptive, and keyword-rich within 20–70 characters. (4) Write substantive, self-contained paragraphs averaging 50+ characters that maintain meaning when extracted. (5) Display visible publication and update dates using machine-readable time elements. (6) Add author attribution with credentials and integrate author information into your schema markup. Our tool provides specific, prioritized recommendations for each failing check, so you can tackle fixes systematically rather than guessing where to start.
Which AI engines does AEO optimize for?
Our AEO checker is designed to optimize content for all major AI-powered answer engines currently shaping the search landscape. This includes ChatGPT (with its browsing and search capabilities), Perplexity AI, Google AI Overviews (formerly Search Generative Experience), Microsoft Copilot / Bing Chat, Claude, and emerging AI search platforms. While each engine has its own algorithms, they all share a common need: well-structured, clearly attributed, machine-readable content that can be reliably extracted and cited. By following the 10-factor framework our checker evaluates, you're optimizing for the structural and semantic patterns that all major AI engines rely on — making your content universally answer-engine ready rather than tailored to any single platform.
Does AEO replace traditional SEO?
No — AEO does not replace traditional SEO; it extends and enhances it. Traditional SEO fundamentals like quality content, fast page speed, mobile responsiveness, and proper heading structure remain essential. AEO adds an additional layer of optimization specifically for AI citation: structured data markup, Q&A formatting, date and author signals, and content extractability. The most effective strategy combines both approaches: use traditional SEO to rank well in search results, and use AEO to ensure your content is the one AI engines choose to cite when generating answers. Many AEO optimizations — like implementing schema markup and improving content structure — simultaneously boost your traditional SEO performance, making the combined approach more efficient than treating them as separate disciplines.
