Understanding AI Crawlers
Two Types of AI Crawling
Type 1: Training Data Collection
Purpose: Collect content to train foundation models
Frequency: Periodic (months/years between crawls)
Used by: GPTBot (OpenAI), Google-Extended, CCBot
Example:
GPTBot crawls your site → Content included in GPT-5 training
→ Model "learns" from your content
→ Can cite you in future answers (if content quality high)
Allow if: Want maximum AI visibility long-term
Block if: Proprietary content, competitive concerns
Type 2: RAG/Real-Time Indexing
Purpose: Index content for real-time answer generation
Frequency: Continuous (daily/weekly)
Used by: Perplexity, SearchGPT, Claude (web search)
Example:
User asks question → AI searches indexed content
→ Pulls fresh data from your site
→ Cites you in answer
Allow if: Want immediate citations, fresh content visibility
Block if: Prefer only trained model citations
The Crawler Dilemma
Allow All Crawlers:
Pros:
✓ Maximum AI visibility
✓ Training data + RAG citations
✓ Long-term model knowledge
✓ Real-time answer inclusion
Cons:
✗ Content used without compensation
✗ Competitive intelligence risk
✗ Server load from crawling
✗ Potential IP concerns
Block All Crawlers:
Pros:
✓ Content protection
✓ No unauthorized training
✓ Reduced server load
✓ Control over usage
Cons:
✗ Zero AI visibility
✗ No citations in AI answers
✗ Miss out on AI traffic
✗ Competitive disadvantage
Selective Approach (Recommended):
Allow: Platforms where you want visibility
Block: Platforms with concerns
Monitor: Track which crawlers provide value
Example:
✓ Allow GPTBot (ChatGPT is dominant)
✓ Allow ClaudeBot (quality audience)
✗ Block CCBot (Common Crawl - too broad)
? Monitor Google-Extended (evaluate impact)

Crawler Identification
Check your server logs:
# Find AI crawler visits
grep -E "GPTBot|ClaudeBot|Google-Extended|PerplexityBot|CCBot" \
/var/log/apache2/access.log
# Example log entry:
66.249.66.1 - - [18/Jan/2025:10:15:32] "GET /crm-guide" 200
"GPTBot/1.0 (+https://openai.com/gptbot)"
Strategic Crawler Management
Decision Framework
Question 1: Is your content proprietary/competitive?
Yes → Block all or most crawlers
No → Allow selective crawlers
Question 2: Do you monetize via ads/subscriptions?
Yes (ads) → Allow crawlers (citations drive awareness)
Yes (subscriptions) → Block crawlers (protect premium content)
No → Allow crawlers (maximize reach)
Question 3: Is content updated frequently?
Yes (daily/weekly) → Prefer RAG crawlers (Perplexity)
No (monthly/yearly) → Prefer training crawlers (GPTBot)
Question 4: What's your AI strategy?
Maximize visibility → Allow all
Selective presence → Allow top 3-5 platforms
Content protection → Block all
Common Strategies
Strategy 1: Open Access (Default)
Who: SaaS companies, service businesses, content marketers
Goal: Maximum AI visibility
Approach: Allow all AI crawlers
robots.txt:
# Allow all AI crawlers (default - no blocking)
User-agent: *
Allow: /
Strategy 2: Selective Blocking
Who: Publishers, paid content creators
Goal: Balance visibility and protection
Approach: Allow major platforms, block data aggregators
robots.txt:
# Allow ChatGPT, Claude
User-agent: GPTBot
Allow: /
User-agent: Claude-Web
Allow: /
# Block Common Crawl (too broad)
User-agent: CCBot
Disallow: /
# Block Perplexity (competes with our search traffic)
User-agent: PerplexityBot
Disallow: /
Strategy 3: Premium Content Protection
Who: News sites, premium publishers
Goal: Protect paid content, allow free content
Approach: Block crawlers from premium sections
robots.txt:
# Block AI from premium content
User-agent: GPTBot
Disallow: /premium/
Disallow: /subscriber/
Allow: /
User-agent: Claude-Web
Disallow: /premium/
Allow: /
Strategy 4: Complete Blocking
Who: Proprietary research, competitive intelligence firms
Goal: Total content protection
Approach: Block all AI crawlers
robots.txt:
# Block all AI crawlers
User-agent: GPTBot
Disallow: /
User-agent: Claude-Web
Disallow: /
User-agent: Google-Extended
Disallow: /
User-agent: PerplexityBot

Advanced Patterns
Pattern 1: Allow Public, Block Private
# Public marketing content - allow AI
User-agent: GPTBot
Allow: /blog/
Allow: /guides/
Allow: /resources/
Disallow: / # Block everything else by default
# Then allow specific public sections
Allow: /about/
Allow: /contact/
# Explicitly block private sections
Disallow: /dashboard/
Disallow: /admin/
Disallow: /api/
Disallow: /internal/
Pattern 2: Time-Based Protection
# Protect recent content (manually update)
User-agent: GPTBot
Disallow: /blog/2025/ # Current year protected
Allow: /blog/2024/ # Last year allowed
Allow: /blog/2023/
Allow: /blog/
# Use case: Give paid subscribers 6-12 month exclusive access
Pattern 3: Content Type Differentiation
# Allow guides (evergreen, want citations)
User-agent: GPTBot
Allow: /guides/
Allow: /tutorials/
# Block news (time-sensitive, traffic-dependent)
Disallow: /news/
Disallow: /breaking/
# Allow documentation (helpful citations)
Allow: /docs/
Meta Tag Alternative
For specific pages, use meta tag:
<!-- Block all AI crawlers from this page -->
<meta name="robots" content="noai, noimageai">
<!-- Or specific crawlers -->
<meta name="GPTBot" content="noindex, nofollow">
<meta name="Claude-Web" content="noindex">
Use when:
- Need page-specific control
- Dynamic content (CMS)
- A/B testing crawler impact
Monitoring Crawler Access
Server Log Analysis
Track crawler visits:
# Daily crawler report
grep -E "GPTBot|ClaudeBot|Google-Extended|PerplexityBot" \
/var/log/apache2/access.log | \
awk '{print $1, $7, $9}' | \
sort | uniq -c
# Output example:
45 GPTBot /blog/crm-guide 200
23 GPTBot /pricing 200
12 ClaudeBot /blog/crm-guide 200
8 PerplexityBot /guides/setup 403 (blocked)
Analytics Integration:
// Google Analytics custom dimension
if (navigator.userAgent.includes('GPTBot')) {
gtag('event', 'ai_crawler', {
'crawler': 'GPTBot',
'page': window.location.pathname
});
}
Impact Measurement
Before/After Blocking:
Month 1 (Allow all):
- GPTBot visits: 450/month
- Citation Rate: 28%
- AI-driven traffic: 320 visitors
Month 2 (Block Perplexity):
- PerplexityBot visits: 0 (blocked)
- Citation Rate: 25% (-3pp, Perplexity citations lost)
- AI-driven traffic: 280 visitors (-40)
Decision: Re-allow Perplexity (citations worth server load)
