AI-Crawler Blocking Index

A robots.txt census of the Tranco top 1,000,000 domains (June 2026): which AI crawlers does each site block? Every domain's /robots.txt is fetched and parsed for 20 AI-crawler user-agents (GPTBot, CCBot, ClaudeBot, Google-Extended, Bytespider, …) and whether each is Disallow: /'d. CC BY 4.0.

Headline

998,497 domains scanned; 629,565 (63.1%) serve a robots.txt.
9.33% fully block at least one major AI crawler (a User-agent: X group with Disallow: /) — 14.8% of robots-serving sites.
Most-blocked: GPTBot 7.4% ≈ CCBot 7.2% (the open Common Crawl corpus is blocked nearly as hard as OpenAI's own crawler), then Bytespider 6.8%, ClaudeBot 6.7%, Amazonbot 6.6%, Google-Extended 6.3%.
Concentrated at the head: ~13% of the top 10,000 block an AI crawler, fading to ~9% across the long tail — the inverse of managed anti-bot / WAF adoption.
By kind: content/publisher sites block hardest (News & media 80.6%, Entertainment 69%, Reference 44%); transactional/functional sites barely block (E-commerce 11%, Search 2.9%, Telecom 2.8%).
7.19% block every bot via a blanket User-agent: * / Disallow: / (the parked tail).

Files

data/results.jsonl.gz — one JSON record per domain (gzipped), 998,497 rows.
data/sample.jsonl — 200-row uncompressed preview.
data/summary.json — headline aggregates: per-crawler blocking, the rank gradient, totals.

Read it: gzip -dc data/results.jsonl.gz | head, or in Python for line in gzip.open("data/results.jsonl.gz","rt"): rec = json.loads(line).

Schema (one JSON record per line)

domain, rank (Tranco), scheme, robots_status, has_robots, names_ai (AI user-agents named in robots.txt), blocks_ai (AI user-agents with Disallow: /), blocks_any_ai, star_disallow_root.

Methodology

One GET /robots.txt per domain (https first, http fallback) from a datacenter IP, parsed into User-agent groups. 20 AI user-agents tracked across OpenAI, Anthropic, Google, Common Crawl, ByteDance, Meta, Amazon, Apple, Perplexity, Cohere and others. robots.txt is a published request, not an enforced wall — this measures stated policy, not traffic. Same domain universe as the Anti-Bot Adoption Index — the two datasets join on domain.
