What is AIMP?
AIMP (AI Manifest Protocol) is the open standard for AEO (AI Engine Optimization) — optimizing your content to be discovered and cited by AI systems like ChatGPT, Claude, and Perplexity.
As AI increasingly answers user queries directly, traditional SEO is losing effectiveness. AIMP helps you adapt to this new reality by:
- AI Identification: Require AI systems to identify themselves (operators must be transparent)
- Access Control: Allow/block specific AI operators, set usage policies
- Structured Content: Serve optimized manifests (20-30x faster than HTML scraping)
- Citation Guidance: Tell AIs how to properly cite your content
- AEO Analytics: Track which AIs visit your site, measure your AIRS score
Core Files
/ai.txt— Entry point (like robots.txt)/ai-manifest.json— Unified manifest (identity + policy + content)/ai-manifest.toon— Optimized format (40% fewer tokens)/ai-report.json— Analytics & AIRS score
Read the full specification in README.md.
AI Identification (Required)
AIMP requires AI systems to identify themselves via the AIMP-Identity header:
GET /ai-manifest.json
AIMP-Identity: {"operator":"OpenAI","model":"GPT-4"}
Without identification, requests are blocked (403 Forbidden). This ensures:
- ✅ Publishers know which AIs access their content
- ✅ Publishers can allow/block specific operators
- ✅ Transparent AI usage (aligned with EU AI Act)
- ✅ AEO analytics for optimizing citations
AEO Benefits (Think SEO for AI)
- Be Cited by AIs: Structured content = higher chance of citation
- Track AI Traffic: See which AIs visit, which pages they access
- Measure AIRS Score: 0-100 score for AI readability (like Domain Authority)
- Control Access: Block bad actors, allow trusted operators
- 40% Token Savings: TOON format = lower costs for AI systems
AIMP Certified Badge

- Enterprise ($299/mo, unlimited): Custom integrations, SLA, account manager
Getting Started
To implement AIMP, serve these files from your domain root:
/ai.txt— Points to your manifest files/ai-manifest.jsonor/ai-manifest.toon— Your site's manifest/ai-report.json(optional) — Analytics for AEO tracking
# /ai.txt
# AI Manifest Protocol (AIMP) — entry file
Manifest: /ai-manifest.json
ManifestOptimized: /ai-manifest.toon
Report: /ai-report.json
Version: 1.1
The ai-manifest file contains your site's identity, policy, and content layer (pages with titles, summaries, topics).
Format Comparison: JSON vs TOON
JSON Format (ai-manifest.json)
Use when: Universal compatibility is required
{
"version": "1.0",
"site": "https://example.com",
"identity": { "name": "Example Inc." },
"policy": { "allow": ["read", "summarize"] },
"content": {
"pages": [
{ "url": "/", "title": "Home", "summary": "..." }
]
}
}
✅ Universal support · ✅ Easy to debug · ❌ Verbose (~12,000 tokens for 100 pages)
TOON Format (ai-manifest.toon)
Use when: Optimizing for AI consumption (recommended)
version: 1.0
site: https://example.com
identity: (name: Example Inc.)
policy: (allow: [read, summarize])
content: (
pages[3]{url,title,summary}:
/,Home,Welcome to our site
/about,About,Learn about us
/contact,Contact,Get in touch
)
✅ 40% fewer tokens · ✅ Better AI parsing (73.9% vs 69.7%) · ✅ Structural validation
Best practice: Serve both formats, let AI choose based on support.
AIRS — AI Readability Score
AIRS (AI Readability Score) measures how well your content is optimized for AI systems (0-100).
Think of it as Domain Authority for the AI era. A higher AIRS score means:
- ✅ More likely to be cited by ChatGPT, Claude, Perplexity
- ✅ Better structured content for AI parsing
- ✅ Higher quality responses when users ask about your topics
- ✅ Competitive advantage in AEO
AIRS Components
- Structure (30%): Valid manifest, schema compliance, metadata completeness
- Coverage (30%): Number of pages, topics covered, linkability
- Clarity (20%): Summary quality, conciseness, keyword density
- Freshness (20%): Content recency, update frequency
