Will AI search engines
cite your content?
AI search engines cite content that directly answers questions, uses structured data, and demonstrates clear topical authority. AI Grade Tool scores your page 0–100 on exactly those signals — across ChatGPT, Perplexity, Google AI Overviews, and Gemini — and shows exactly what to fix.
Paste a URL or your text. Get a citation readiness score out of 100, your most quotable passage, and a rewritten opening — free.
Not an academic citation tool. AI Grade Tool helps publishers and content teams get cited by AI search engines — not students checking bibliography footnotes.

Get your score, passage, and fixes
Your results show your GEO score, the passage most likely to be cited by AI, your weakest signals, and — for pages scoring below 70 — a rewritten opening paragraph optimized for citation.
Built for the AI engines your audience uses
AI Grade Tool grades content against the signals Perplexity, ChatGPT Search, Gemini, and Claude actually use to decide what to cite.
Perplexity
Optimized for real-time search and citation signals like extractable claims and authority indicators.
ChatGPT Search
Structured for content hierarchy and clean semantic markup that ChatGPT can parse and extract passages from.
Google Gemini
Tailored for Google's multimodal model and the same E-E-A-T signals Google has always rewarded in search.
Claude
Built for clean reasoning chains and citation-friendly structure that Anthropic's models prefer when generating answers.
Grok
Optimized for X's real-time data integration and conversational citation style that Grok uses to generate answers.
Microsoft Copilot
Aligned with Bing's citation model and Microsoft's hybrid search-AI pipeline for enterprise and consumer queries.
Meta AI
Calibrated for Meta's AI assistant across WhatsApp, Instagram, and Facebook — where conversational authority drives citations.

Traditional SEO measures whether you rank. GEO measures whether you get quoted. When users ask AI a question, they don't see a list of links — they see one answer with a handful of cited sources. Being one of those sources is the new top of the funnel.
SEO gets you found. GEO gets you cited.
They work together but optimize for different things.
Traditional SEO
- Goal: rank on page one
- Optimizes for keywords and backlinks
- Measured by clicks and rankings
- Pages need to be crawlable
- Audience clicks to find the answer
Generative Engine Optimization
- Goal: be the cited source
- Optimizes for extractable claims and evidence
- Measured by citation frequency
- Passages need to be quotable
- Audience reads the answer directly
GEO doesn't replace SEO — it extends it. Good SEO ensures AI engines can find your content. Good GEO ensures they actually cite it.
How the score works
Six criteria, weighted by how much AI engines rely on them.
Extractable Claims
Does the first 100 words contain a self-contained factual claim an AI can lift directly? Specific assertions score high; throat-clearing intros score zero.
Evidence Density
Specific statistics, dates, named sources, and proper nouns. "According to [Source] in [Year]" patterns score highest. "Studies show" scores zero.
Entity Clarity
Are subjects named explicitly rather than referenced with pronouns? Repeated canonical entity names score higher than ambiguous "it" and "they."
Passage Independence
Can each paragraph stand alone without surrounding context? Critical for AI retrieval chunking. Paragraphs that rely on earlier setup lose points.
Information Structure
Headers, bullet points, comparison tables, and short paragraphs under 3 sentences. Scannable structure that AI can chunk efficiently.
Freshness Signals
Does the content include recent dates, current statistics, and timely references? AI engines prefer citing content that signals up-to-date information.

How to Get Your Content Cited by AI Search Engines
The foundational guide to making your content visible in ChatGPT, Perplexity, and Google AI Overviews. Covers clarity, trust signals, specificity, and structure.
Why Isn't My Content Showing Up in AI Search?
Your page ranks on Google but never appears in AI answers. Here's why AI search skips some content — and the fixes that actually work.
Do AI Search Engines Use Backlinks?
Authority still matters in AI search — but backlinks alone won't get your content cited. Here's the realistic middle ground and what actually drives AI citation visibility.
Frequently Asked Questions
How do I get my content cited by ChatGPT? +
ChatGPT cites content that directly answers questions in the first paragraph, uses specific facts with named sources, and is accessible to OpenAI's GPTBot crawler. AI Grade Tool scores your page against all of these citation signals and shows the exact fix for each one you fail.
What makes a page appear in Google AI Overviews? +
Google AI Overviews extract content that answers a clear question directly in the opening paragraph, uses structured data like FAQPage or HowTo JSON-LD, and is indexed without noindex restrictions. The AIO Checker on AI Grade Tool evaluates all four of these signals and returns a single pass/fail verdict per signal.
How does AI Grade Tool score my content? +
AI Grade Tool evaluates your content across six weighted signals — extractable claims (25 pts), evidence density (25 pts), entity clarity (20 pts), passage independence (15 pts), information structure (10 pts), and freshness signals (5 pts) — and returns a score from 0–100 in 5–15 seconds. You also get your most quotable passage, your weakest signal, and a suggested rewrite for pages scoring below 70.
What is a GEO score and how is it calculated? +
A GEO score is a 0–100 measure of how citation-ready your content is for AI search engines. AI Grade Tool calculates it by evaluating six weighted content signals — 75 or above is Citation-Ready, 50–74 is Developing, and below 50 means the content needs significant restructuring before AI engines will consistently cite it.
Does adding schema markup help with AI citation? +
Yes — FAQPage and HowTo JSON-LD schema are among the strongest signals for Google AI Overview eligibility. AI Grade Tool's FAQ Generator creates a complete FAQPage schema block from any URL or pasted content, ready to paste into your page's HTML in one step.
Why is my content not showing up in Perplexity answers? +
Perplexity typically skips content that does not answer a question directly in the first paragraph, lacks specific facts or named sources, or has PerplexityBot blocked in robots.txt. AI Grade Tool checks all three of these issues with the GEO Score Checker and Robots.txt Checker.
What's the difference between SEO and GEO optimization? +
SEO optimizes for ranking in traditional search result pages — measured by clicks and rankings. GEO (Generative Engine Optimization) optimizes for being cited as a source in AI-generated answers — measured by citation frequency across ChatGPT, Perplexity, Google AI Overviews, and Gemini. A page can rank on page one of Google and still score below 30 on AI Grade Tool.
How do I check if AI crawlers can access my site? +
Use AI Grade Tool's Robots.txt Checker, which tests your domain against 17 known AI crawlers including GPTBot (OpenAI), ClaudeBot (Anthropic), and PerplexityBot — and shows exactly which ones are allowed or blocked. Blocking any of the 10 AI search crawlers removes your content from that platform's real-time AI answers.
What content format do AI search engines prefer? +
AI search engines prefer content that opens with a direct answer to a specific question, uses short paragraphs under three sentences, names specific entities rather than using pronouns, and includes structured data markup. AI Grade Tool's GEO score identifies which of these formatting signals your content is missing.
How do I improve my GEO score? +
The three most impactful fixes are: rewrite your opening paragraph to answer a specific question in the first sentence, add specific facts and named sources, and add FAQPage JSON-LD schema. AI Grade Tool identifies exactly which signals you're missing and — for pages below 70 — rewrites your opening paragraph to show what a citation-ready version looks like.
What is the AIO Checker and how is it different from the GEO score? +
The AIO Checker evaluates four signals specific to Google AI Overview eligibility: crawlability, schema markup, freshness, and answer clarity — returning a binary pass/fail verdict per signal. The GEO score is a broader 0–100 rating across six weighted signals for all AI engines including ChatGPT, Perplexity, Gemini, and Claude.
Can I check a competitor page for AI citation readiness? +
Yes — use AI Grade Tool's Compare Pages tool for a side-by-side GEO signal comparison on any two public URLs. You'll see exactly which of the four AI citation signals your page wins or loses against a competitor, with specific fix tips for each signal you lose.
Is AI Grade Tool free to use? +
AI Grade Tool's six analysis tools are free with no account required — submit a URL or paste text, get your score in 5–15 seconds, and share your permanent results page. Paid plans add automated monitoring and bulk scoring: Pro ($9.99/mo) unlocks daily Dashboard tracking and the Domain Monitor, and Agency ($79.99/mo) adds Bulk Sweep for scoring up to 50 URLs at once.
Which tools are free and which require a paid plan? +
Six AI Grade Tool analysis tools are 100% free with no sign-up: GEO Score Checker, AIO Checker, Robots.txt Checker, Compare Pages, AI Keyword Finder, and FAQ Generator. Paid plans add automated tracking and team features: Pro ($9.99/mo) unlocks the Dashboard with daily auto-tracking, score history, and Page Intelligence, plus the Domain Monitor; Business ($29.99/mo) adds priority scanning and advanced analytics across 3 domains and 50 pages, with the Competitor Gap Tracker coming soon; and Agency ($79.99/mo) adds Bulk Sweep for up to 50 URLs across 10 domains and 250 pages, with a Citation Tracker and white-label PDF reports coming soon.
What is AI Grade Tool? +
AI Grade Tool is a free AI citation readiness grader that scores web content 0–100 on how likely it is to be cited by AI search engines like ChatGPT, Perplexity, Google AI Overviews, and Gemini. It identifies your weakest citation signals, surfaces your most quotable passage, and rewrites your opening paragraph for pages scoring below 70.
How accurate is the citation readiness score? +
The GEO score is a strong directional signal based on a structured rubric calibrated for citation patterns across Perplexity, ChatGPT Search, Google Gemini, and Claude — but it is not a guarantee of citation. AI citation also depends on query relevance, domain authority, and real-time model behavior. Use it as a practical diagnostic, not a placement promise.
